Iconic watch art prints. Made in Switzerland, lifetime guarantee

The must-have Macro Loupe for all watch lovers

<p><strong>ZRC</strong> is a watch brand founded in <strong>1904</strong> 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.</p>
<h3>6 o&rsquo;clock crown, monobloc case and French Navy spirit</h3>
<p>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). <strong>In practice, the 6 o&rsquo;clock crown and CPS prevent the watch from being worn unless the crown is fully screwed down</strong>, reducing user error prior to immersion; ECS helps flush out salt to prevent crystallization under the bezel.</p>
<h3>Grands Fonds and contemporary variants</h3>
<p>The current collection translates the historical DNA (legibility, field ergonomics, tool-watch silhouette) into multiple sizes and performance levels. <strong>Whichever the model, the 6 o&rsquo;clock signature ensures instant readability and an immediately recognisable identity</strong>.</p>
<ul>
<li><strong>ZRC Grands Fonds 300</strong> &mdash; Core diver inspired by 1964, 300 m, bold legibility for versatile daily wear.</li>
<li><strong>ZRC MN64 R&eacute;&eacute;dition</strong> &mdash; Tribute to French Navy specifications with period-correct dial and bezel cues.</li>
<li><strong>ZRC Grands Fonds 38</strong> &mdash; Smaller 38 mm option retaining the 6 o&rsquo;clock crown signature for slimmer wrists.</li>
<li><strong>ZRC Grands Fonds 3000 Titanium</strong> &mdash; Extreme titanium variant with heightened depth rating and lighter weight.</li>
<li><strong>ZRC Securicode</strong> &mdash; Reinterpretation of a late-1950s/1960s theme with historical design elements.</li>
</ul>
<h3>Positioning: pro tool, pricing and distribution</h3>
<p>The brand&rsquo;s stance is that of an independent Swiss &ldquo;diving instrument,&rdquo; with production volumes <em>not disclosed</em> and selective distribution (specialist retailers and direct sales). <strong>As a guide, many steel references sit around &euro;2,500&ndash;3,000, while technical titanium pieces exceed &euro;4,000</strong>; 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.</p>
<h3>Conclusion</h3>
<p>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 <strong>Dialicious customer reviews</strong> to understand comfort, real-world legibility and on-wrist feel.</p>

C'est son design et sa simplicité chic qui m'ont séduit. Et puis je l'ai essayé et c'est son confort et sa robustesse qui m'ont convaincu. Une montre que l'on peut porter tous les jours et pour toutes ses activités, une montre polyvalente dédiée à la plongée mais avec un esthétisme qui s'allie aussi bien à des activités professionnelles !
Un coup coeur qui est dans le top de ma collection

It was its design and chic simplicity that captivated me. Then I tried it on, and its comfort and robustness won me over. A watch you can wear every day and for all your activities, a versatile watch designed for diving but with an aesthetic that also works well for professional settings! A real favorite that's now at the top of my collection.
