The must-have Macro Loupe for all watch lovers

The ZRC Grands Fonds is a watch that immediately inspires confidence. Robust, reliable, and perfectly suited for diving, it remains surprisingly versatile for everyday wear. Its unique character, highly durable construction with its crown at 6 o'clock, and comfortable fit on the wrist make it a watch I wear with great pleasure. A true tool watch with a strong personality!

A robust and incredibly versatile diver

All-terrain watch equipped with a Seiko NH35 movement. 
Purchased during the Kickstarter campaign which took inspiration from the Bianchi workshops based in Marseille. 

Despite the crown being on the left, the watch remains very comfortable on my right wrist. A perfect watch for any diving watch enthusiast. 


JB200

A perfect watch for every day. Robust, versatile, I can wear it with jeans and a t-shirt as well as with a suit. It remains quite discreet (36mm). The jubilee bracelet is very comfortable but it is also very beautiful mounted on a leather strap. I highly recommend this watch.

Rolex Datejust 1601

ZRC is a watch brand founded in 1904 in Geneva, Switzerland, by Edmond Zuccolo and Joseph Rochet. Born in the field of pocket-watch chains and later expandable metal bracelets, the brand now caters to enthusiasts of iconic tool divers, made famous by its Grands Fonds developed for the French Navy from the 1960s onward.
<h3>6 o&rsquo;clock crown, monobloc case and French Navy spirit</h3>
Engineered to meet the operational demands of French Navy mine-clearance divers, the Grands Fonds features a 6 o&rsquo;clock crown, a monobloc case and in-house solutions such as ECS (Easy Clean System) and CPS (Crown Protection System). In practice, the 6 o&rsquo;clock crown and CPS prevent the watch from being worn unless the crown is fully screwed down, reducing user error prior to immersion; ECS helps flush out salt to prevent crystallization under the bezel.
<h3>Grands Fonds and contemporary variants</h3>
The current collection translates the historical DNA (legibility, field ergonomics, tool-watch silhouette) into multiple sizes and performance levels. Whichever the model, the 6 o&rsquo;clock signature ensures instant readability and an immediately recognisable identity.
<ul>
<li>ZRC Grands Fonds MN64 &mdash; Core diver inspired by 1964, 300 m, bold legibility for versatile daily wear.</li>
<li>ZRC Grands Fonds Hertiage &mdash; Smaller 38 mm option retaining the 6 o&rsquo;clock crown signature for slimmer wrists.</li>
<li>ZRC Securicode &mdash; Reinterpretation of a late-1950s/1960s theme with historical design elements.</li>
</ul>
<h3>Positioning: pro tool, pricing and distribution</h3>
The brand&rsquo;s stance is that of an independent Swiss &ldquo;diving instrument,&rdquo; with production volumes not disclosed and selective distribution (specialist retailers and direct sales). As a guide, many steel references sit around &euro;2,500&ndash;3,000, while technical titanium pieces exceed &euro;4,000; special editions or precious-metal variants are significantly higher. Presence is established in Europe such as <a href="https://www.soprana.com/zrc-1904/?lang=en">Soprana</a> in Italy or <a href="https://junod-lausanne.ch/fr/collections/zrc">Junod</a> in Switzerland, and selected Asian/Middle-Eastern markets through a tight retail network.
<h3>Conclusion</h3>
ZRC speaks to those who value immediately recognisable tool-watch design with functional clarity and a strong signature. Your choice will likely fall between versatile daily wear (Grands Fonds 300/38), an emphatic historical link (MN64, Securicode), or a more technical, extreme approach (Grands Fonds 3000 Titanium). Ergonomics benefit from the 6 o&rsquo;clock crown and CPS safety; purists will appreciate the overall coherence. To refine your decision beyond the spec sheet, rely on Dialicious customer reviews to understand comfort, real-world legibility and on-wrist feel.

La ZRC Grands Fonds MN64 &Eacute;dition Limit&eacute;e Phenix incarne une vision particuli&egrave;rement symbolique et engag&eacute;e de la montre de plong&eacute;e utilitaire. D&eacute;velopp&eacute;e &agrave; l&rsquo;occasion des 120 ans de ZRC, cette &eacute;dition limit&eacute;e ne se contente pas de proposer une variation esth&eacute;tique de la Grands Fonds MN64 1000M : elle s&rsquo;inscrit dans une v&eacute;ritable d&eacute;marche m&eacute;morielle autour du sous-marin Q157 PHENIX, disparu en baie de Cam Ranh au Vietnam le 15 juin 1939. Par cette montre, ZRC rend hommage aux 76 marins disparus lors du naufrage, tout en associant cette &eacute;vocation historique &agrave; l&rsquo;une de ses plongeuses les plus techniques.
Cette &eacute;dition est limit&eacute;e &agrave;&nbsp;200 pi&egrave;ces et propos&eacute;e au tarif de 3 990 &euro;.
Ce qui rend cette r&eacute;f&eacute;rence particuli&egrave;rement int&eacute;ressante, c&rsquo;est sa capacit&eacute; &agrave; conjuguer charge comm&eacute;morative, coh&eacute;rence technique et identit&eacute; de plongeuse professionnelle. La marque pr&eacute;cise que la montre est mise en valeur dans un coffret sp&eacute;cifique comprenant la tape de bouche du PHENIX ainsi qu&rsquo;une reproduction du sous-marin &agrave; l&rsquo;&eacute;chelle 1/750e. Mais au-del&agrave; de cette dimension d&rsquo;hommage, la montre reste pleinement fid&egrave;le &agrave; la logique ZRC : une construction monobloc, une lunette ECS&reg;, une couronne &agrave; 6 h avec Crown Protection System&trade; et une &eacute;tanch&eacute;it&eacute; extr&ecirc;me, au service d&rsquo;une vraie montre-outil.
<h3>Quelles sont les caract&eacute;ristiques de la ZRC Grands Fonds MN64 &Eacute;dition Limit&eacute;e Phenix ?</h3>
Bo&icirc;tier de la ZRC Grands Fonds MN64 &Eacute;dition Limit&eacute;e Phenix
Le bo&icirc;tier de la ZRC Grands Fonds MN64 &Eacute;dition Limit&eacute;e Phenix est r&eacute;alis&eacute; en acier inoxydable 316L amagn&eacute;tique et adopte une construction monobloc avec fond et couronne viss&eacute;s. Son diam&egrave;tre de 41,5 mm lui donne une pr&eacute;sence affirm&eacute;e au poignet, en phase avec sa vocation de montre de plong&eacute;e professionnelle. ZRC pr&eacute;cise &eacute;galement une conformit&eacute; &agrave; la norme ISO764 : 4800 A/m, renfor&ccedil;ant encore son profil technique. Le fond &agrave; d&eacute;formation programm&eacute;e, exclusivit&eacute; de la marque, participe &agrave; cette logique fonctionnelle. Le bo&icirc;tier est surmont&eacute; d&rsquo;un verre saphir bomb&eacute; de 3 mm avec traitement antireflet.
Cadran bleu soleill&eacute; et identit&eacute; visuelle
Le cadran de la MN64 &Eacute;dition Limit&eacute;e Phenix se distingue par son bleu soleill&eacute;, d&eacute;velopp&eacute; par ZRC pour imiter les reflets de l&rsquo;eau en mer ainsi que les rayons du soleil p&eacute;n&eacute;trant les profondeurs abyssales. Cette intention donne &agrave; la montre une profondeur visuelle plus expressive qu&rsquo;un simple cadran bleu uni. Le r&eacute;sultat reste coh&eacute;rent avec l&rsquo;esprit technique du mod&egrave;le tout en lui apportant une dimension plus &eacute;motionnelle, particuli&egrave;rement pertinente dans le cadre de cette &eacute;dition hommage. Ce cadran joue donc &agrave; la fois sur la lisibilit&eacute;, sur l&rsquo;&eacute;vocation du monde sous-marin et sur une forme de pr&eacute;sence plus sensible que strictement instrumentale.
Lunette, couronne et architecture fonctionnelle
L&rsquo;un des &eacute;l&eacute;ments les plus distinctifs de cette ZRC r&eacute;side dans son architecture de plong&eacute;e. La lunette tournante unidirectionnelle &agrave; 60 divisions re&ccedil;oit un insert en c&eacute;ramique et s&rsquo;appuie sur le syst&egrave;me ECS&reg;, brevet&eacute; par ZRC, con&ccedil;u pour favoriser un rin&ccedil;age optimal apr&egrave;s plong&eacute;e et &eacute;viter l&rsquo;accumulation d&rsquo;impuret&eacute;s ou de cristaux de sel entre la lunette et la bo&icirc;te. La couronne viss&eacute;e &agrave; 6 heures, &agrave; pas invers&eacute;, constitue une autre signature forte. Elle fait partie du Crown Protection System&trade; et participe pleinement &agrave; l&rsquo;identit&eacute; fonctionnelle de la Grands Fonds. Cette approche montre bien que, chez ZRC, le dessin reste toujours subordonn&eacute; &agrave; une logique d&rsquo;usage r&eacute;el.&nbsp;
Calibre et performances
La ZRC Grands Fonds MN64 &Eacute;dition Limit&eacute;e Phenix est anim&eacute;e par le calibre Sellita SW300-1 &ldquo;Elabor&eacute;&rdquo;. Ce mouvement suisse &agrave; remontage automatique bat &agrave; 28 800 alternances par heure (4 Hz) et offre une r&eacute;serve de marche de 56 heures. ZRC annonce une pr&eacute;cision de +5 secondes par jour, avec une amplitude donn&eacute;e comme comprise entre 0 et +10 secondes par jour maximum. La montre affiche les heures, minutes et secondes, dans une logique de lisibilit&eacute; et de fiabilit&eacute;. Le choix du SW300-1 Elabor&eacute; renforce la cr&eacute;dibilit&eacute; de la pi&egrave;ce dans un registre de montre-outil hautement technique.
Bracelet et confort
La fiche officielle indique que cette &eacute;dition Phenix est mont&eacute;e sur un bracelet en caoutchouc FKM, compatible avec une boucle ardillon en acier. ZRC le d&eacute;crit comme un bracelet inspir&eacute; du design du bracelet m&eacute;tal, tr&egrave;s confortable et disponible dans de nombreux coloris sur la gamme. Sur cette version, ce choix du FKM est coh&eacute;rent avec la vocation de plong&eacute;e de la montre : il apporte souplesse, r&eacute;sistance et confort dans un usage sportif ou aquatique, sans nuire &agrave; la force visuelle du bo&icirc;tier.&nbsp;
&Eacute;tanch&eacute;it&eacute; et usage au quotidien
La ZRC Grands Fonds MN64 &Eacute;dition Limit&eacute;e Phenix se distingue par un niveau d&rsquo;&eacute;tanch&eacute;it&eacute; particuli&egrave;rement impressionnant. La marque annonce une &eacute;tanch&eacute;it&eacute; garantie pour 1000 m&egrave;tres et test&eacute;e &agrave; 1500 m&egrave;tres, ce qui la place clairement dans la cat&eacute;gorie des plongeuses &agrave; vocation s&eacute;rieuse. Cette capacit&eacute; technique, combin&eacute;e &agrave; la construction monobloc, &agrave; la couronne s&eacute;curis&eacute;e et &agrave; la lunette ECS&reg;, donne au mod&egrave;le une cr&eacute;dibilit&eacute; forte dans l&rsquo;univers des montres-outils. Pourtant, malgr&eacute; cette radicalit&eacute;, son cadran bleu soleill&eacute; et sa dimension comm&eacute;morative lui conf&egrave;rent aussi une pr&eacute;sence plus singuli&egrave;re et narrative qu&rsquo;une simple plongeuse instrumentale.&nbsp;
<h3>ZRC Grands Fonds MN64 &Eacute;dition Limit&eacute;e Phenix : une plongeuse comm&eacute;morative, robuste et sans concession</h3>
Avec la MN64 &Eacute;dition Limit&eacute;e Phenix, ZRC propose bien plus qu&rsquo;une simple variation de sa Grands Fonds. La limitation &agrave; 200 pi&egrave;ces, l&rsquo;hommage au sous-marin Q157 PHENIX, le cadran bleu soleill&eacute;, le bo&icirc;tier monobloc, la lunette ECS&reg;, la couronne &agrave; 6 h et le Sellita SW300-1 Elabor&eacute; composent un ensemble d&rsquo;une grande coh&eacute;rence. Cette montre s&eacute;duira les amateurs qui recherchent une vraie plongeuse de caract&egrave;re, techniquement cr&eacute;dible, visuellement forte et porteuse d&rsquo;une dimension historique forte.
<h3>Conclusion</h3>
La ZRC Grands Fonds MN64 &Eacute;dition Limit&eacute;e Phenix s&rsquo;adresse aux amateurs qui recherchent une montre de plong&eacute;e robuste, originale et charg&eacute;e de sens. Gr&acirc;ce &agrave; son architecture fonctionnelle unique, &agrave; son &eacute;tanch&eacute;it&eacute; impressionnante, &agrave; son mouvement suisse &eacute;prouv&eacute; et &agrave; son cadran bleu soleill&eacute; inspir&eacute; du monde sous-marin, elle propose une lecture particuli&egrave;rement coh&eacute;rente de la plongeuse professionnelle comm&eacute;morative contemporaine.

The ZRC Grands Fonds MN64 Limited Edition Phenix embodies a particularly symbolic and purposeful vision of the utilitarian dive watch. Developed for ZRC&rsquo;s 120th anniversary, this limited edition is not merely an aesthetic variation of the Grands Fonds MN64 1000M. It is part of a true memorial approach centred on the submarine Q157 PHENIX, lost in Cam Ranh Bay in Vietnam on 15 June 1939. Through this watch, ZRC pays tribute to the 76 sailors who disappeared in the sinking, while pairing this historical evocation with one of its most technical divers.
This edition is limited to&nbsp;200 pieces and priced at&nbsp;3,990 EUR.&nbsp;
What makes this reference especially interesting is its ability to combine commemorative meaning, technical coherence and the identity of a professional dive watch. The brand explains that the watch is presented in a specific box set including the PHENIX muzzle cap as well as a 1/750 scale reproduction of the submarine. Yet beyond this tribute dimension, the watch remains entirely faithful to the ZRC logic: a monobloc construction, ECS&reg; bezel, crown at 6 o&rsquo;clock with Crown Protection System&trade; and extreme water resistance, all in the service of a true tool watch.&nbsp;
<h3>What are the characteristics of the ZRC Grands Fonds MN64 Limited Edition Phenix?</h3>
Case of the ZRC Grands Fonds MN64 Limited Edition Phenix
The case of the ZRC Grands Fonds MN64 Limited Edition Phenix is made of amagnetic 316L stainless steel and uses a monobloc construction with screw-down caseback and crown. Its 41.5 mm diameter gives it strong wrist presence, in keeping with its purpose as a professional dive watch. ZRC also specifies compliance with ISO764: 4800 A/m, which further reinforces its technical profile. The programmed-deformation caseback, exclusive to the brand, belongs to the same functional logic. The case is topped by a 3 mm domed sapphire crystal with anti-reflective treatment.&nbsp;
Sunburst blue dial and visual identity
The dial of the MN64 Limited Edition Phenix stands out through its sunburst blue finish, developed by ZRC to imitate reflections on the sea and the rays of sunlight penetrating abyssal depths. This intention gives the watch greater visual depth than a simple flat blue dial. The result remains coherent with the model&rsquo;s technical spirit while also adding a more emotional dimension, especially relevant in the context of this tribute edition. The dial therefore works both on legibility and on evoking the underwater world, while giving the watch a more narrative presence than a purely instrumental diver.
Bezel, crown and functional architecture
One of the most distinctive elements of this ZRC lies in its diving-oriented architecture. The unidirectional rotating bezel with 60 divisions receives a ceramic insert and relies on the brand&rsquo;s patented ECS&reg; system, designed to ensure optimal rinsing after a dive and prevent impurities or salt crystals from accumulating between bezel and case. The screw-down crown at 6 o&rsquo;clock, with reverse thread, is another strong signature. It forms part of the Crown Protection System&trade; and fully contributes to the functional identity of the Grands Fonds. This approach shows clearly that, at ZRC, design always remains subordinate to a logic of real-world use.&nbsp;
Movement and performance
The ZRC Grands Fonds MN64 Limited Edition Phenix is powered by the Sellita SW300-1 &ldquo;Elabor&eacute;&rdquo; calibre. This Swiss automatic movement beats at 28,800 vibrations per hour (4 Hz) and offers a 56-hour power reserve. ZRC states an accuracy of +5 seconds per day, with an amplitude given as between 0 and +10 seconds per day maximum. The watch displays hours, minutes and seconds in a logic of readability and reliability. The choice of the SW300-1 Elabor&eacute; reinforces the credibility of the piece within a highly technical tool-watch register.
Strap and comfort
The official page indicates that this Phenix edition is fitted with an FKM rubber strap, compatible with a steel pin buckle. ZRC describes it as a strap inspired by the design of the metal bracelet, highly comfortable and available in several colours across the range. On this version, the use of FKM is coherent with the diving vocation of the watch: it brings flexibility, resistance and comfort in sporty or aquatic use without compromising the strong visual character of the case.&nbsp;
Water resistance and everyday use
The ZRC Grands Fonds MN64 Limited Edition Phenix stands out through a particularly impressive level of water resistance. The brand states water resistance guaranteed to 1000 metres and tested to 1500 metres, clearly placing it in the category of serious dive watches. This technical capability, combined with the monobloc construction, secured crown and ECS&reg; bezel, gives the model strong credibility within the world of tool watches. Yet despite this radical nature, its sunburst blue dial and commemorative dimension also lend it a more singular and narrative presence than a simple instrument diver.&nbsp;
<h3>ZRC Grands Fonds MN64 Limited Edition Phenix: a commemorative diver, robust and uncompromising</h3>
With the MN64 Limited Edition Phenix, ZRC offers far more than a simple variation of its Grands Fonds. The 200-piece limitation, the tribute to the Q157 PHENIX submarine, the sunburst blue dial, the monobloc case, ECS&reg; bezel, crown at 6 o&rsquo;clock and Sellita SW300-1 Elabor&eacute; all come together in a highly coherent whole. This watch will appeal to enthusiasts looking for a true characterful diver that is technically credible, visually strong and backed by a powerful historical dimension.&nbsp;
<h3>Conclusion</h3>
The ZRC Grands Fonds MN64 Limited Edition Phenix is aimed at enthusiasts looking for a dive watch that is robust, original and full of meaning. Thanks to its unique functional architecture, impressive water resistance, proven Swiss movement and sunburst blue dial inspired by the underwater world, it offers a particularly coherent reading of the contemporary commemorative professional diver.&nbsp;
Dialicious customer reviews are a relevant way to choose the watch that truly suits you.

La lisibilit&eacute; reste au c&oelig;ur du projet, dans une montre pens&eacute;e avant tout pour la plong&eacute;e et l&rsquo;usage professionnel.

(Mise &agrave; jour Mai 2026)

The ZRC Grands Fonds MN64 Heterium Rubber embodies a particularly assertive vision of the utilitarian dive watch. A contemporary heir to the original Grands Fonds 300&reg;, this rubber-strap version retains all the technical radicality that defines ZRC while offering a more modern and immediate interpretation of the professional dive watch. With its navy-to-black gradient dial, satin-finished case and FKM rubber strap, this version fully embraces its place in the world of uncompromising tool watches.
The model is listed at 3,390 &euro;.
What makes this reference especially interesting is its ability to combine the aesthetics of a traditional dive watch with deeply distinctive technical solutions. ZRC is not simply offering a robust dive watch: the brand builds an object in which every element responds to a functional logic, whether it is the crown at 6 o&rsquo;clock, the Crown Protection System&trade;, the ECS&reg; bezel system or the programmed-deformation caseback. The MN64 Heterium Rubber therefore belongs to an approach where technical coherence matters just as much as style.
<h3>What are the characteristics of the ZRC Grands Fonds MN64 Heterium Rubber?</h3>
Case of the ZRC Grands Fonds MN64 Heterium Rubber
The case of the ZRC Grands Fonds MN64 Heterium Rubber is made of amagnetic 316L stainless steel and uses a monobloc construction with screw-down caseback and crown. Its 41.5 mm diameter gives it strong wrist presence, in keeping with its purpose as a professional dive watch. ZRC also specifies compliance with ISO764: 4800 A/m, which further reinforces its technical profile. The programmed-deformation caseback, exclusive to the brand, is part of the same functional logic. The case is topped by a 3 mm domed sapphire crystal with anti-reflective treatment.&nbsp;
Dial and readability
The dial of the MN64 Heterium Rubber stands out through its navy-to-black gradient, a combination that gives it visual depth and real personality. This chromatic transition reinforces the model&rsquo;s contemporary dimension without taking it away from its purely utilitarian register. Readability remains central to the project, in a watch designed first and foremost for diving and professional use. The whole therefore retains a very coherent face, where colour and function are intelligently balanced.&nbsp;
Bezel, crown and functional architecture
One of the most distinctive elements of this ZRC lies in its diving-oriented architecture. The unidirectional rotating bezel with 60 divisions receives a ceramic insert and relies on the brand&rsquo;s patented ECS&reg; system, designed to ensure optimal rinsing after a dive and to prevent impurities or salt crystals from accumulating between bezel and case. The screw-down crown at 6 o&rsquo;clock, with reverse thread, is another strong signature. It forms part of the Crown Protection System&trade;, and the strap cannot even be closed unless the crown is fully screwed down. This unusual solution perfectly expresses the ZRC philosophy: every design detail must also reinforce safety and functionality.&nbsp;
Movement and performance
The ZRC Grands Fonds MN64 Heterium Rubber is powered by the Sellita SW300-1 &ldquo;Elabor&eacute;&rdquo; calibre. This Swiss automatic movement beats at 28,800 vibrations per hour (4 Hz) and offers a 56-hour power reserve. The watch displays hours, minutes and seconds in a logic of readability and reliability. ZRC clearly emphasises the seriousness of the movement, chosen to support the robust and professional spirit of the piece.&nbsp;
Strap and comfort
In this configuration, the MN64 Heterium is fitted with an FKM rubber strap. ZRC describes it as a strap inspired by the design of the metal bracelet, compatible with a steel pin buckle, highly comfortable and available in several colours. This use of FKM is coherent with the diving vocation of the watch: it brings flexibility, resistance and comfort in sporty or aquatic use while also reinforcing the more contemporary character of this Rubber version.
Water resistance and everyday use
The ZRC Grands Fonds MN64 Heterium Rubber stands out through a particularly impressive level of water resistance. The brand states water resistance guaranteed to 1000 metres and tested to 1500 metres, clearly placing it in the category of serious dive watches. This technical capability, combined with the monobloc construction, secured crown and ECS&reg; bezel, gives the model strong credibility within the world of tool watches. Yet despite this radical nature, its gradient dial and FKM strap also allow it to remain wearable in broader everyday use.
<h3>ZRC Grands Fonds MN64 Heterium Rubber: a dive watch French in spirit, robust and uncompromising</h3>
With the MN64 Heterium Rubber, ZRC offers a dive watch that fully embraces its functional logic. The monobloc case, the crown at 6 o&rsquo;clock, the ECS&reg; system, the extreme water resistance, the Sellita SW300-1 Elabor&eacute; and the FKM strap all come together in a highly coherent whole. This watch will appeal to enthusiasts looking for a true characterful diver that is technically credible, visually strong and faithful to a tradition of engineering-led watchmaking built around real use.
<h3>Conclusion</h3>

La ZRC Grands Fonds MN64 Titane Rubber propose une interpr&eacute;tation encore plus technique, l&eacute;g&egrave;re et radicale de la plongeuse professionnelle selon ZRC. Avec cette version en titane grade 5 mont&eacute;e sur bracelet caoutchouc FKM, la manufacture genevoise pousse la collection Grands Fonds MN64 vers un registre plus contemporain, plus performant et plus confortable au poignet. Cette r&eacute;f&eacute;rence GF4226521118 conserve l&rsquo;architecture embl&eacute;matique de la Grands Fonds, mais l&rsquo;adapte &agrave; une mati&egrave;re plus l&eacute;g&egrave;re que l&rsquo;acier, plus moderne dans son ressenti et particuli&egrave;rement coh&eacute;rente avec une montre de plong&eacute;e extr&ecirc;me.
Elle est propos&eacute;e au tarif de&nbsp;4290 &euro;.
Ce qui rend cette ZRC Grands Fonds MN64 Titane Rubber particuli&egrave;rement impressionnante, c&rsquo;est son &eacute;quilibre entre h&eacute;ritage militaire, innovations techniques et usage quotidien. La montre reprend les grands marqueurs de la maison : bo&icirc;tier monobloc, couronne &agrave; 6 heures, Crown Protection System&trade;, lunette ECS&reg; et &eacute;tanch&eacute;it&eacute; hors norme. Mais le titane grade 5 change profond&eacute;ment l&rsquo;exp&eacute;rience au poignet. Plus l&eacute;g&egrave;re, plus technique et plus actuelle, cette version donne &agrave; la Grands Fonds une dimension tout-terrain tr&egrave;s s&eacute;duisante, capable de parler autant aux plongeurs exigeants qu&rsquo;aux amateurs de montres-outils haut de gamme.
<h3>Quelles sont les caract&eacute;ristiques de la ZRC Grands Fonds MN64 Titane Rubber ?</h3>
Bo&icirc;tier de la ZRC Grands Fonds MN64 Titane Rubber
Le bo&icirc;tier de la ZRC Grands Fonds MN64 Titane Rubber est r&eacute;alis&eacute; en titane grade 5. Cette mati&egrave;re apporte une combinaison tr&egrave;s pertinente pour une montre de plong&eacute;e : l&eacute;g&egrave;ret&eacute;, r&eacute;sistance m&eacute;canique, r&eacute;sistance &agrave; la corrosion et confort sup&eacute;rieur au port&eacute;. Le bo&icirc;tier adopte un diam&egrave;tre de 41,5 mm, une dimension coh&eacute;rente avec l&rsquo;ADN Grands Fonds et suffisamment affirm&eacute;e pour conserver une vraie pr&eacute;sence instrumentale. Sa construction monobloc, avec fond et couronne viss&eacute;s, renforce la robustesse de l&rsquo;ensemble et s&rsquo;inscrit dans la tradition technique de ZRC. Cette architecture donne &agrave; la montre une allure imm&eacute;diatement reconnaissable, avec ce dessin hexagonal puissant qui distingue les Grands Fonds des plongeuses plus conventionnelles.
Cadran d&eacute;grad&eacute; et appliques Lumicast 3D
Le cadran d&eacute;grad&eacute; de cette MN64 Titane Rubber apporte une profondeur visuelle tr&egrave;s contemporaine. Il est associ&eacute; &agrave; des appliques Lumicast 3D, qui renforcent la lisibilit&eacute; tout en donnant davantage de volume au cadran. Cette approche permet de conserver l&rsquo;esprit fonctionnel d&rsquo;une vraie plongeuse, sans renoncer &agrave; une pr&eacute;sence esth&eacute;tique forte. Le d&eacute;grad&eacute; cr&eacute;e un effet plus dynamique qu&rsquo;un cadran noir uniforme, tandis que les index en relief accentuent l&rsquo;impression de robustesse et de technicit&eacute;. La montre reste pens&eacute;e pour &ecirc;tre lue rapidement, mais elle gagne une personnalit&eacute; plus moderne, plus premium et plus expressive.
Lunette ECS&reg; et esprit plongeuse professionnelle
La lunette de la ZRC Grands Fonds MN64 Titane Rubber int&egrave;gre le syst&egrave;me ECS&reg;, l&rsquo;une des signatures techniques de la marque. Cette lunette tournante unidirectionnelle crant&eacute;e &agrave; 60 divisions re&ccedil;oit un insert en c&eacute;ramique et participe &agrave; la vocation professionnelle du mod&egrave;le. Le syst&egrave;me ECS&reg; a &eacute;t&eacute; pens&eacute; pour faciliter le rin&ccedil;age de la montre apr&egrave;s une immersion en eau sal&eacute;e, en aidant &agrave; &eacute;vacuer les impuret&eacute;s et les cristaux de sel log&eacute;s entre la lunette et le bo&icirc;tier. Ce type de d&eacute;tail illustre parfaitement l&rsquo;approche ZRC : une esth&eacute;tique singuli&egrave;re, mais toujours justifi&eacute;e par l&rsquo;usage. La lunette ne sert donc pas seulement &agrave; donner une apparence technique &agrave; la montre ; elle participe r&eacute;ellement &agrave; sa logique de plongeuse con&ccedil;ue pour durer.
Couronne &agrave; 6 heures et Crown Protection System&trade;
La couronne positionn&eacute;e &agrave; 6 heures demeure l&rsquo;un des &eacute;l&eacute;ments les plus embl&eacute;matiques de la Grands Fonds. Sur cette MN64 Titane Rubber, elle s&rsquo;inscrit dans le Crown Protection System&trade;, avec une couronne viss&eacute;e &agrave; double &eacute;tanch&eacute;it&eacute; et pas invers&eacute;. Ce positionnement atypique permet de prot&eacute;ger la couronne et d&rsquo;am&eacute;liorer le confort au poignet, notamment en &eacute;vitant les points de pression sur le dos de la main. Il donne aussi &agrave; la montre une identit&eacute; visuelle imm&eacute;diatement reconnaissable. L&agrave; o&ugrave; beaucoup de plongeuses reprennent des codes assez proches, ZRC conserve une architecture vraiment diff&eacute;rente, h&eacute;rit&eacute;e d&rsquo;une r&eacute;flexion fonctionnelle et non d&rsquo;un simple effet de style.
&Eacute;tanch&eacute;it&eacute; extr&ecirc;me et construction technique
L&rsquo;un des arguments les plus forts de cette ZRC Grands Fonds MN64 Titane Rubber est son niveau d&rsquo;&eacute;tanch&eacute;it&eacute;. La fiche officielle annonce une &eacute;tanch&eacute;it&eacute; garantie &agrave; 3 000 m&egrave;tres et test&eacute;e &agrave; 5 100 m&egrave;tres. Ce niveau de performance d&eacute;passe tr&egrave;s largement les besoins du quotidien et place cette r&eacute;f&eacute;rence dans un registre de montre de plong&eacute;e extr&ecirc;me. Le fond &agrave; d&eacute;formation programm&eacute;e, exclusivit&eacute; ZRC&reg;, participe &agrave; cette recherche de robustesse et de ma&icirc;trise des contraintes. M&ecirc;me si la majorit&eacute; des propri&eacute;taires ne pousseront jamais la montre dans de telles conditions, cette capacit&eacute; technique donne &agrave; l&rsquo;objet une cr&eacute;dibilit&eacute; rare et renforce son statut de v&eacute;ritable montre-outil.
Calibre et performances
La ZRC Grands Fonds MN64 Titane Rubber est anim&eacute;e par le calibre Sellita SW300-1 &Eacute;labor&eacute;. Ce mouvement automatique suisse est un choix coh&eacute;rent pour une plongeuse hautement fonctionnelle : fiable, fin, &eacute;prouv&eacute; et facile &agrave; entretenir dans la dur&eacute;e. Il bat &agrave; 28 800 alternances par heure, soit 4 Hz, affiche une amplitude maximale annonc&eacute;e &agrave; 315 degr&eacute;s et offre une r&eacute;serve de marche de 56 heures. Les fonctions restent volontairement essentielles : heures, minutes et secondes. Cette simplicit&eacute; sert la vocation instrumentale de la montre. La MN64 Titane Rubber ne cherche pas &agrave; multiplier les complications ; elle privil&eacute;gie la robustesse, la lisibilit&eacute; et la fiabilit&eacute;.
Bracelet FKM et confort
La version Titane Rubber est mont&eacute;e sur un bracelet en caoutchouc FKM, compatible avec une boucle ardillon en titane. Ce choix est particuli&egrave;rement coh&eacute;rent avec le bo&icirc;tier en titane grade 5. Le caoutchouc FKM est appr&eacute;ci&eacute; pour sa r&eacute;sistance, sa souplesse et son confort, notamment dans un contexte nautique ou sportif. Inspir&eacute; par le design du bracelet m&eacute;tal, il permet de conserver une continuit&eacute; esth&eacute;tique avec l&rsquo;univers Grands Fonds, tout en offrant une sensation plus l&eacute;g&egrave;re et plus d&eacute;contract&eacute;e. Cette configuration rend la montre plus facile &agrave; porter au quotidien qu&rsquo;une version int&eacute;gralement mont&eacute;e sur m&eacute;tal, tout en conservant une vraie l&eacute;gitimit&eacute; de plongeuse.
Usage au quotidien et personnalit&eacute;
Malgr&eacute; ses performances extr&ecirc;mes, la ZRC Grands Fonds MN64 Titane Rubber reste une montre &eacute;tonnamment pertinente au quotidien. Son bo&icirc;tier en titane r&eacute;duit la sensation de poids, son bracelet FKM apporte du confort et son diam&egrave;tre de 41,5 mm reste coh&eacute;rent pour une plongeuse moderne. Visuellement, elle conserve une pr&eacute;sence forte, avec une architecture tr&egrave;s ZRC, un cadran d&eacute;grad&eacute; et une couronne &agrave; 6 heures qui la rendent imm&eacute;diatement identifiable. Elle s&eacute;duira les amateurs qui recherchent une montre technique, diff&eacute;rente, suisse, robuste et dot&eacute;e d&rsquo;une vraie histoire. C&rsquo;est une montre qui ne se contente pas de sugg&eacute;rer l&rsquo;aventure : elle est construite pour l&rsquo;encaisser.

<hr>
The ZRC Grands Fonds MN64 Titanium Rubber offers an even more technical, lighter and more radical interpretation of the professional dive watch according to ZRC. With this grade 5 titanium version fitted with an FKM rubber strap, the Geneva-based manufacture pushes the Grands Fonds MN64 collection toward a more contemporary, more performance-driven and more comfortable register. This reference GF4226521118 retains the emblematic Grands Fonds architecture, but adapts it to a material that is lighter than steel, more modern in feel and particularly coherent for an extreme dive watch.
It is priced at&nbsp;CHF 4,090.
What makes the ZRC Grands Fonds MN64 Titanium Rubber especially impressive is its balance between military heritage, technical innovation and everyday usability. The watch retains the Maison&rsquo;s key markers: monobloc case, crown at 6 o&rsquo;clock, Crown Protection System&trade;, ECS&reg; bezel and outstanding water resistance. But grade 5 titanium deeply changes the wrist experience. Lighter, more technical and more current, this version gives the Grands Fonds a highly appealing all-terrain dimension, speaking both to demanding divers and to enthusiasts of high-end tool watches.
<h3>What are the characteristics of the ZRC Grands Fonds MN64 Titanium Rubber?</h3>
Case of the ZRC Grands Fonds MN64 Titanium Rubber
The case of the ZRC Grands Fonds MN64 Titanium Rubber is made of grade 5 titanium. This material offers a very relevant combination for a dive watch: lightness, mechanical strength, corrosion resistance and superior wearing comfort. The case measures 41.5 mm in diameter, a dimension coherent with the Grands Fonds identity and assertive enough to preserve a genuinely instrumental presence. Its monobloc construction, with screwed caseback and crown, reinforces the robustness of the whole and fits directly into ZRC&rsquo;s technical tradition. This architecture gives the watch an immediately recognisable appearance, with the powerful hexagonal design that distinguishes the Grands Fonds from more conventional dive watches.
Gradient dial and 3D Lumicast appliques
The gradient dial of this MN64 Titanium Rubber gives the watch a highly contemporary visual depth. It is paired with 3D Lumicast appliques, which reinforce legibility while adding more volume to the dial. This approach preserves the functional spirit of a true diver while giving the watch strong aesthetic presence. The gradient effect feels more dynamic than a uniform black dial, while the raised indexes accentuate the impression of robustness and technicality. The watch remains designed for fast reading, but gains a more modern, more premium and more expressive personality.
ECS&reg; bezel and professional diver spirit
The bezel of the ZRC Grands Fonds MN64 Titanium Rubber integrates the ECS&reg; system, one of the brand&rsquo;s technical signatures. This 60-division unidirectional rotating notched bezel is fitted with a ceramic insert and contributes to the professional vocation of the model. The ECS&reg; system was designed to help rinse the watch after immersion in salt water, assisting in the removal of impurities and salt crystals lodged between the bezel and the case. This type of detail perfectly illustrates ZRC&rsquo;s approach: a distinctive aesthetic, but always justified by use. The bezel therefore does not merely give the watch a technical appearance; it genuinely contributes to its logic as a dive watch built to last.
6 o&rsquo;clock crown and Crown Protection System&trade;
The crown positioned at 6 o&rsquo;clock remains one of the most emblematic elements of the Grands Fonds. On this MN64 Titanium Rubber, it forms part of the Crown Protection System&trade;, with a screw-down crown featuring dual sealing and an inverted thread. This unusual position helps protect the crown and improves comfort on the wrist, notably by avoiding pressure points on the back of the hand. It also gives the watch an immediately recognisable visual identity. Where many dive watches follow fairly similar codes, ZRC retains a truly different architecture, born from functional thinking rather than simple styling.
Extreme water resistance and technical construction
One of the strongest arguments of this ZRC Grands Fonds MN64 Titanium Rubber is its level of water resistance. The official page states water resistance guaranteed to 3,000 metres and tested to 5,100 metres. This level of performance far exceeds daily needs and places the reference firmly in the realm of extreme dive watches. The programmed-deformation caseback, exclusive to ZRC&reg;, contributes to this search for robustness and controlled resistance to pressure. Even though most owners will never push the watch into such conditions, this technical capability gives the object rare credibility and reinforces its status as a true tool watch.
Movement and performance
The ZRC Grands Fonds MN64 Titanium Rubber is powered by the Sellita SW300-1 &Eacute;labor&eacute; calibre. This Swiss automatic movement is a coherent choice for a highly functional diver: reliable, slim, proven and easy to service over time. It beats at 28,800 vibrations per hour, or 4 Hz, has a stated maximum amplitude of 315 degrees and offers a 56-hour power reserve. The functions remain deliberately essential: hours, minutes and seconds. This simplicity serves the instrumental vocation of the watch. The MN64 Titanium Rubber does not try to multiply complications; it prioritises robustness, legibility and reliability.
FKM rubber strap and comfort
The Titanium Rubber version is fitted with an FKM rubber strap, compatible with a titanium pin buckle. This choice is particularly coherent with the grade 5 titanium case. FKM rubber is appreciated for its resistance, flexibility and comfort, especially in nautical or sporty contexts. Inspired by the design of the metal bracelet, it maintains visual continuity with the Grands Fonds universe while offering a lighter and more relaxed feel. This configuration makes the watch easier to wear every day than a full-metal version, while preserving genuine dive-watch legitimacy.
Everyday use and personality
Despite its extreme performance, the ZRC Grands Fonds MN64 Titanium Rubber remains surprisingly relevant for daily wear. Its titanium case reduces the feeling of weight, its FKM strap brings comfort and its 41.5 mm diameter remains coherent for a modern diver. Visually, it retains a strong presence, with a very ZRC architecture, a gradient dial and a 6 o&rsquo;clock crown that make it immediately identifiable. It will appeal to enthusiasts looking for a technical, different, Swiss-made and robust watch with genuine history. This is a watch that does not merely suggest adventure: it is built to withstand it.
<h3>ZRC Grands Fonds MN64 Titanium Rubber: an extreme diver made lighter and more contemporary</h3>
With the Grands Fonds MN64 Titanium Rubber, ZRC offers a dive watch that combines heritage, innovation and modern comfort. The grade 5 titanium monobloc case, 3,000-metre water resistance, ECS&reg; system, 6 o&rsquo;clock crown, Sellita SW300-1 &Eacute;labor&eacute; calibre and FKM strap create an extremely coherent whole. This watch is aimed at enthusiasts of genuine tool watches, but also at those who want a characterful diver that is lighter than steel, more technical in construction and immediately recognisable on the wrist.
<h3>Conclusion</h3>
The ZRC Grands Fonds MN64 Titanium Rubber is aimed at enthusiasts looking for an extreme Swiss diver that is light, technical and endowed with a strong identity. Thanks to its grade 5 titanium case, exceptional water resistance, ECS&reg; system, Crown Protection System&trade; and FKM rubber strap, it offers a highly accomplished interpretation of the contemporary dive watch.
Dialicious customer reviews are a relevant way to choose the watch that truly suits you.
(Updated August 2026)

I had already had a certain hype for the By Stef "1" then I had missed it with other projects and especially another Grand Fond in my collection. (A Spirit whose review I have already posted on Dialicious). I must admit for the anecdote that it was the second ZRC and always a more demanding expectation on a dial that I considered too wise. When the By Stef 2 project started I again came close to correction with another compulsive purchase 😊… and finally… Knowing Stéphane Clouzeau for a few years, I contacted him recently just after the opening night and I benefited from a cancellation. 24h delivery (Pithiviers is not very far from Paris where I live)
From there, ZRC, for me - diver (or ex future diver) is also a story of passions, stories, strict specifications: passing through prestigious ambassadors: the Jacques Cousteau, divers / mine clearers of the Mediterranean ... A story that started 120 years ago and then a more hollow period like many brands and the resurrection. Of the 2000s which is not ephemeral seen from the window and this thanks to a committed CEO whose name is linked to the brand.

I invite you if it is not already done to watch the Podcast of Georges Brunet (CEO of ZRC): For those who have not already listened to it and who would be interested in a Podcast that I found captivating on ZRC.

https://smartlink.ausha.co/des-montres-et-vous/83-georges-brunet-ceo-de-zrc-raconte-en-exclu-le-retour-de-la-grands-fonds

The characteristics of the beauty after these lucubrations:
- the latest Sellita SW300 developed quite precise -5/+5 and 56h of autonomy, it's correct - a minimum now!
- a magnificent blue dial with the look of Deepsea and underlined and raised indexes
- no complications (between us I find that quite superfluous for a diver)
- classic ceramic bezel
- patents that are the pride of the brand like the "rinsing" and evacuation system of salt crystals: ECS… etc.
- an improvement IMHO of the fluidity of the movement / winding thanks to this new movement surely…
A generous package for this By Stef! Soft and comfortable FKM bracelet, a numbered bronze plate (?), tools for changing the bracelet, the “special force” box 😅

A colorful favorite!

Ollech &amp; Wajs est une maison horlog&egrave;re suisse fond&eacute;e en 1956 &agrave; Zurich par Joseph Ollech et Albert Wajs ; d&rsquo;abord d&eacute;taillant puis acteur de la vente par correspondance, le duo a b&acirc;ti sa r&eacute;putation sur des montres &laquo; tool &raquo; robustes &mdash; plongeuses, militaires, d&rsquo;aviation &mdash; vendues aux particuliers comme aux forces arm&eacute;es, avant d&rsquo;orchestrer un retour au premier plan au cours des ann&eacute;es 2010 avec une gamme contemporaine qui r&eacute;active les signatures historiques.
<h3>Zurich, Stockerstrasse et la vente par correspondance&thinsp;: les d&eacute;buts d&rsquo;un label outil</h3>
D&egrave;s l&rsquo;ouverture de leur petite boutique zurichoise, les fondateurs s&rsquo;attachent &agrave; proposer des montres fiables &agrave; prix tenu, puis &eacute;tendent rapidement l&rsquo;activit&eacute; vers le courrier et les annonces sp&eacute;cialis&eacute;es, et cette distribution directe fa&ccedil;on &laquo; mail-order &raquo; deviendra l&rsquo;un des marqueurs durables de la marque.&nbsp;Le basculement d&rsquo;un r&ocirc;le de d&eacute;taillant vers la cr&eacute;ation de montres sous leur propre nom s&rsquo;op&egrave;re en quelques ann&eacute;es, avec des lignes d&eacute;di&eacute;es aux usages concrets (terrain, mer, cockpit) et une construction volontairement simple et r&eacute;parable, et l&rsquo;obsession est moins la &laquo; complication &raquo; que l&rsquo;endurance et la lisibilit&eacute;.
Dans les ann&eacute;es 1960, la diffusion s&rsquo;&eacute;tend aux bases am&eacute;ricaines et aux PX, o&ugrave; des montres militaires et de plong&eacute;e sign&eacute;es O&amp;W trouvent un public pr&ecirc;t &agrave; les &eacute;prouver en conditions r&eacute;elles, et cette validation par l&rsquo;usage contribue &agrave; installer l&rsquo;image d&rsquo;un outil professionnel abordable.
<h3>Caribbean 1000 et Ocean Graph&thinsp;: la profondeur, la d&eacute;compression et l&rsquo;imaginaire des grandes eaux</h3>
Au milieu des sixties, la maison se distingue par des plongeuses d&rsquo;avant-garde dont la Ollech &amp; Wajs Caribbean 1000, pi&egrave;ce record annonc&eacute;e pour 1000 m qui cristallise l&rsquo;ambition technique de l&rsquo;&eacute;poque et installe le nom O&amp;W dans le paysage de la plong&eacute;e sportive comme professionnelle, et l&rsquo;association avec des partenaires sp&eacute;cialis&eacute;s nourrit une esth&eacute;tique rationnelle et sans fioritures.
Dans la m&ecirc;me veine, l&rsquo;Ollech &amp; Wajs Ocean Graph introduit une lunette et une logique de lecture con&ccedil;ues pour accompagner la mont&eacute;e du plongeur et les paliers de d&eacute;compression, ancrant la montre dans un usage pr&eacute;cis plut&ocirc;t que dans l&rsquo;&eacute;vocation d&eacute;corative de la mer, et le cadran reste clair pour pr&eacute;server l&rsquo;instantan&eacute;it&eacute; de la lecture sous l&rsquo;eau.
Ces r&eacute;f&eacute;rences historiques, souvent cit&eacute;es et collectionn&eacute;es aujourd&rsquo;hui, ont fa&ccedil;onn&eacute; un langage fait de bo&icirc;tiers costauds, d&rsquo;&eacute;tanch&eacute;it&eacute;s s&eacute;rieuses, de bracelets adapt&eacute;s et de typographies contrast&eacute;es qui affleurent encore dans les mod&egrave;les actuels, et c&rsquo;est cette continuit&eacute; de &laquo; montre-outil &raquo; qui permet de relier le pass&eacute; et le pr&eacute;sent.
<h3>Relance contemporaine, ancrage helv&eacute;tique et cha&icirc;ne courte&thinsp;: le retour d&rsquo;O&amp;W</h3>
Apr&egrave;s avoir travers&eacute; la p&eacute;riode quartz et ralenti la cadence, la marque est reprise par Charles Le Menestrel et relanc&eacute;e &agrave; la fin des ann&eacute;es 2010 avec la volont&eacute; explicite de prolonger l&rsquo;esprit des origines plut&ocirc;t que de s&rsquo;&eacute;parpiller en s&eacute;ries cosm&eacute;tiques, et&nbsp;le bureau de cr&eacute;ation reste &agrave; Zurich tandis que l&rsquo;assemblage et les r&eacute;glages s&rsquo;effectuent dans le Jura suisse.
La d&eacute;marche privil&eacute;gie des mouvements automatiques suisses &eacute;prouv&eacute;s, une architecture de bo&icirc;te simple &agrave; entretenir, des &eacute;tanch&eacute;it&eacute;s cr&eacute;dibles et des bracelets &agrave; la fois robustes et faciles &agrave; vivre au quotidien, et le cahier des charges reprend la triade historique : fiabilit&eacute;, lisibilit&eacute;, r&eacute;parabilit&eacute;.
La relance ne se contente pas de &laquo; r&eacute;&eacute;ditions &raquo; au millim&egrave;tre : elle propose des montres nouvelles inspir&eacute;es des usages historiques, rehausse le soin apport&eacute; aux finitions et met en avant un contr&ocirc;le qualit&eacute; par &eacute;tapes, et le r&eacute;sultat vise une modernit&eacute; pragmatique qui &eacute;vite le pastiche.
<h3>P-101, P-104, Navichron, C-1000 et Ocean Graph&thinsp;: familles actuelles et usages concrets</h3>
Les premi&egrave;res r&eacute;f&eacute;rences de l&rsquo;&egrave;re r&eacute;cente prennent la forme de montres d&rsquo;aviation &agrave; taille contenue, Ollech &amp; Wajs P-101 et Ollech &amp; Wajs P-104, qui relecturent les codes cockpit dans une bo&icirc;te polyvalente autour de 39&ndash;40 mm avec saphir et couronne viss&eacute;e, et elles ciblent une lecture instrumentale et une r&eacute;sistance suffisante pour le quotidien.
C&ocirc;t&eacute; plong&eacute;e, la maison propose aujourd&rsquo;hui la Ollech &amp; Wajs C-1000 (ainsi que des &eacute;ditions anniversaires) comme incarnation contemporaine de l&rsquo;esprit Caribbean : valves, joints, fonds viss&eacute;s et traitements soign&eacute;s s&rsquo;additionnent pour offrir un instrument de mer moderne, et le cadran conserve l&rsquo;intelligibilit&eacute; qui a fait la r&eacute;putation de la lign&eacute;e.
En parall&egrave;le, l&rsquo;Ollech &amp; Wajs Ocean Graph revient sous une forme actualis&eacute;e, avec sa logique de lecture li&eacute;e &agrave; la d&eacute;compression qui en fait une plongeuse de caract&egrave;re imm&eacute;diatement reconnaissable au poignet, et cette signature d&rsquo;usage distingue le mod&egrave;le dans un segment satur&eacute;.
La famille Ollech &amp; Wajs Navichron s&rsquo;adresse &agrave; celles et ceux qui veulent un chronographe &laquo; outil &raquo; lisible, fid&egrave;le &agrave; l&rsquo;esprit O&amp;W sans exc&egrave;s de complexit&eacute;, avec une ergonomie de poussoirs travaill&eacute;e et une &eacute;chelle claire pour structurer le temps court, et le dessin reste volontairement pratique plut&ocirc;t que d&eacute;monstratif.
<ul>
<li>Ollech &amp; Wajs P-101 &mdash; pilote contemporain, diam&egrave;tre contenu, saphir, r&eacute;sistance &agrave; l&rsquo;eau &eacute;lev&eacute;e, cadran tr&egrave;s lisible, usage &laquo; bureau-terrain &raquo;.</li>
<li>Ollech &amp; Wajs P-104 &mdash; variante d&rsquo;aviation avec autre signature de lunette et de marquages, m&ecirc;me esprit robuste.</li>
<li>Ollech &amp; Wajs C-1000 &mdash; plongeuse moderne inspir&eacute;e de la Caribbean, &eacute;tanch&eacute;it&eacute; pouss&eacute;e et lecture directe.</li>
<li>Ollech &amp; Wajs Ocean Graph &mdash; plongeuse instrumentale &agrave; logique de d&eacute;compression, identit&eacute; forte au poignet.</li>
<li>Ollech &amp; Wajs Navichron &mdash; chronographe &laquo; tool &raquo;, cadran a&eacute;r&eacute; et poussoirs francs, lisibilit&eacute; du temps court.</li>
</ul>
Au-del&agrave; des noms, l&rsquo;important est l&rsquo;usage : pilote pour la lisibilit&eacute; &agrave; plat et la r&eacute;sistance aux chocs de la vie active, plongeuse pour l&rsquo;eau et la robustesse, chronographe pour rythmer les t&acirc;ches et les entra&icirc;nements, et ce d&eacute;coupage aide &agrave; choisir une O&amp;W en fonction d&rsquo;un sc&eacute;nario r&eacute;el plut&ocirc;t que d&rsquo;un simple style.
<h3>Signature &laquo; tool watch &raquo;&thinsp;: mat&eacute;riaux, mouvements, dimensions et bracelets</h3>
Les bo&icirc;tiers actuels privil&eacute;gient l&rsquo;acier, des traitements de surface sobres, des lunettes fonctionnelles et des glaces saphir, avec des diam&egrave;tres g&eacute;n&eacute;ralement compris entre 39 et 42 mm pour pr&eacute;server la polyvalence au quotidien, et le port&eacute; se veut stable gr&acirc;ce &agrave; des cornes ma&icirc;tris&eacute;es et des bracelets ajust&eacute;s.
C&ocirc;t&eacute; motorisation, la marque recourt &agrave; des automatiques suisses contemporains adapt&eacute;s &agrave; l&rsquo;usage intensif, certains r&eacute;gl&eacute;s ou certifi&eacute;s selon versions, et l&rsquo;accent est mis sur la facilit&eacute; d&rsquo;entretien par un horloger comp&eacute;tent partout dans le monde, et cette pragmatique m&eacute;canique refl&egrave;te la vocation utilitaire des montres.

<h3>Guide de choix&thinsp;: sc&eacute;nario d&rsquo;usage, lisibilit&eacute; et ergonomie</h3>
Commencez par d&eacute;finir l&rsquo;environnement principal : eau, cockpit, bureau-terrain ou sport chronom&eacute;tr&eacute; ; si l&rsquo;eau domine, une Ollech &amp; Wajs C-1000 ou une Ollech &amp; Wajs Ocean Graph seront naturelles, tandis que P-101/P-104 conviendront aux lectures rapides et aux cadrans &eacute;pur&eacute;s, et le chronographe Navichron servira aux temps courts et aux routines fractionn&eacute;es.
Validez ensuite la lisibilit&eacute; : contraste aiguilles/fond, taille des index, absence de surcharge, visibilit&eacute; de la minuterie et coh&eacute;rence de la lunette avec l&rsquo;usage r&eacute;el, et faites le test &laquo; un m&egrave;tre/un coup d&rsquo;&oelig;il &raquo; en lumi&egrave;re naturelle avant d&rsquo;arr&ecirc;ter votre choix.
Enfin, essayez la montre pour jauger l&rsquo;assise (corne-&agrave;-corne), la couronne dans la paume, la souplesse du bracelet et le tomb&eacute; g&eacute;n&eacute;ral avec vos manches et vos activit&eacute;s, et gardez la version que vous oubliez le plus vite une fois port&eacute;e.
<h3>Conclusion</h3>
Ollech &amp; Wajs demeure identifiable par sa vocation d&rsquo;outil : des montres pens&eacute;es pour l&rsquo;usage, lisibles, robustes et suivies par une cha&icirc;ne suisse claire. Entre plongeuses h&eacute;riti&egrave;res de la Caribbean, pilotes modernes et chronographes de travail, la gamme s&rsquo;articule simplement autour de sc&eacute;narios r&eacute;els.

(Mise &agrave; jour Ao&ucirc;t 2025)

Ollech &amp; Wajs is a Swiss watch company founded in 1956 in Zurich by Joseph Ollech and Albert Wajs; initially a retailer and then a mail-order operator, the duo built a reputation on robust tool watches&mdash;divers, military pieces and pilot instruments&mdash;sold to civilians and service members alike, before orchestrating a modern comeback in the late 2010s with a contemporary range that revives the brand&rsquo;s historic signatures.
<h3>Zurich, Stockerstrasse and mail order: the beginnings of a tool-driven label</h3>
From their small Zurich storefront, the founders soon moved from selling other brands to shipping their own watches by post, and this direct &ldquo;mail-order&rdquo; route became a lasting hallmark of the company.&nbsp;The shift from retailing to making watches under their own name took only a few years, with dedicated lines for concrete use cases (field, sea, cockpit) and constructions that favoured simple, repairable mechanics, and the focus was less on &ldquo;complication&rdquo; than on endurance and clarity.
In the 1960s, distribution extended to US military PX stores, where O&amp;W military and dive watches were tried in real-world conditions by service members, and this usage-led validation helped cement the image of an affordable professional instrument.
<h3>Caribbean 1000 and Ocean Graph: depth, decompression and the great-waters playbook</h3>
By the mid-sixties the brand stood out with cutting-edge divers, notably the Ollech &amp; Wajs Caribbean 1000, a thousand-metre-rated watch that crystallised the era&rsquo;s technical ambition and lodged the O&amp;W name in both recreational and professional diving, and partnerships with specialist makers fed a rational, no-nonsense aesthetic.
In the same spirit, the Ollech &amp; Wajs Ocean Graph brought a bezel and reading logic tailored to ascent and decompression stops, rooting the watch in a specific task rather than mere maritime d&eacute;cor, and the dial stayed clean to preserve underwater glance legibility.
These historic references&mdash;often cited and collected today&mdash;shaped a language of stout cases, serious water-resistance, practical bracelets and high-contrast typography that still surfaces in current models, and this through-line of &ldquo;tool first&rdquo; connects past to present.
<h3>Contemporary relaunch, Swiss anchoring and a short chain: O&amp;W&rsquo;s return</h3>
After weathering the quartz era and slowing down, the brand was revived in the late 2010s by Charles Le Menestrel with the explicit aim of extending the founding spirit rather than scattering into cosmetic runs, and&nbsp;design remains in Zurich while assembly and adjustment take place in the Swiss Jura.
The approach favours proven Swiss automatic movements, serviceable case architecture, credible water-resistance and bracelets built for comfort and durability, and the specification re-embraces the classic triad: reliability, legibility, serviceability.&nbsp;The comeback is not a millimetre-for-millimetre facsimile exercise; instead, it offers new watches inspired by historic use, upgrades finishing and emphasises stepwise quality control, and the outcome is a pragmatic modernity that avoids pastiche.
<h3>P-101, P-104, Navichron, C-1000 and Ocean Graph: today&rsquo;s families and real use</h3>
The first modern releases took the form of compact pilot watches, the Ollech &amp; Wajs P-101 and Ollech &amp; Wajs P-104, which reinterpret cockpit codes in versatile 39&ndash;40 mm cases with sapphire and screw-down crowns, and they target instrumental reading and all-day resilience.
On the dive side, the brand offers the Ollech &amp; Wajs C-1000 (along with anniversary editions) as a contemporary take on the Caribbean ethos: seals, casebacks, and careful treatment combine into a modern sea instrument, and the dial retains the intelligibility that made the line&rsquo;s reputation.
In parallel, the Ollech &amp; Wajs Ocean Graph returned in an updated form, with its decompression-centred readout making for an instantly recognisable diver on the wrist, and this task-specific signature sets it apart in a crowded segment.
The Ollech &amp; Wajs Navichron family serves those who want a readable, work-ready chronograph true to the O&amp;W spirit, with well-judged pushers and crisp scales for short-time duties, and the design stays deliberately practical rather than showy.
<ul>
<li>Ollech &amp; Wajs P-101 &mdash; contemporary pilot, compact diameter, sapphire, strong water-resistance, very legible dial for desk-to-field wear.</li>
<li>Ollech &amp; Wajs P-104 &mdash; aviation variant with a different bezel and markings signature, same robust intent.</li>
<li>Ollech &amp; Wajs C-1000 &mdash; modern diver inspired by the Caribbean, serious water-proofing and direct readout.</li>
<li>Ollech &amp; Wajs Ocean Graph &mdash; instrumental diver with decompression logic, strong identity on the wrist.</li>
<li>Ollech &amp; Wajs Navichron &mdash; &ldquo;tool&rdquo; chronograph, open dial and assertive pushers, clarity in short-time work.</li>
</ul>
Beyond names, what matters is use: a pilot for flat-plane readability and shock tolerance in active life; a diver for water and sturdiness; a chronograph to pace tasks and training, and this split helps pick an O&amp;W by real scenario rather than by style alone.
<h3>Tool-watch signature: materials, movements, dimensions and straps</h3>
Current cases prioritise steel, sober surface treatments, functional bezels and sapphire crystals, with diameters largely between 39 and 42 mm to sustain daily versatility, and on-wrist stability comes from disciplined lug spans and well-matched bracelets.
Mechanically, the brand uses modern, Swiss automatic calibres suited to intensive use&mdash;some adjusted or certified depending on versions&mdash;while ensuring that any competent watchmaker can service them, and this pragmatic mechanics reflects the utilitarian brief.
Bracelets&mdash;steel, RAF/NATO-type textile or rubber&mdash;are chosen for security, water-readiness and comfort, with buckles and end-links designed to minimise hot-spots, and modularity lets a single watch adapt to very different contexts.
<h3>Positioning, prices, channels and buyer profiles</h3>
O&amp;W sits in a &ldquo;quality tool&rdquo; segment: tidy finishing without ostentation, coherent spec sheets, tight quality control and messaging anchored in use rather than prestige, and the value proposition seeks instrument credibility rather than luxury posturing.
Distribution blends direct online sales with a small partner network and a didactic narrative about heritage and use, and this short channel supports coherent pricing and a clear link to the workshop.&nbsp;The core audience mixes owners who prefer watches to &ldquo;do&rdquo; rather than to &ldquo;show,&rdquo; recreational divers, travellers who prize sturdiness and professionals who need reliable, serviceable objects, and the brand resonates with those who trust proof of wear over glossy claims.
<h3>Selection guide: use case, legibility and ergonomics</h3>
Start by mapping your main environment&mdash;water, cockpit, desk-to-field or timed sport; if water rules, a Ollech &amp; Wajs C-1000 or Ollech &amp; Wajs Ocean Graph is natural, whereas P-101/P-104 suit quick, uncluttered reads, and the Navichron chronograph serves intervals and structured routines.
Next validate legibility: hand-to-dial contrast, index size, minimal clutter, minute track visibility and bezel logic that matches how you actually use it, and run the &ldquo;one-metre/one-glance&rdquo; test in natural light before deciding.
Finally, try the watch to judge stance (lug-to-lug), crown feel in the palm, bracelet suppleness and how it sits with sleeves and tasks, and keep the version you forget the fastest once strapped on.
<h3>Conclusion</h3>
Ollech &amp; Wajs remains identifiable by its purpose-built vocation: watches made for use&mdash;readable, robust and supported by a clear Swiss chain. Between divers that channel the Caribbean legacy, modern pilot pieces and work-ready chronographs, the range is organised simply around real-world scenarios. To choose well, start with where you&rsquo;ll wear it, test clarity and comfort, then tune material and strap; you&rsquo;ll land on a capable instrument that ages well. To square these cues with long-term ownership feedback, a helpful compass remains Dialicious customer reviews.
