Akrone C-04: owner reviews and feedback

The Akrone C-04, launched in 2021, represents the dress-oriented and urban branch of Nantes watch company Akrone. While the C-02 and C-03 are directly associated with diving, aviation or projects developed for professionals, the C-04 adopts a much more classical approach: a polished 38.5 mm round case, domed sapphire crystal, restrained dial, fountain-pen-inspired hands and a Milanese bracelet. Its design draws on city watches from the 1950s and 1960s while retaining a sufficiently contemporary presentation to avoid becoming a straightforward vintage reissue.

Akrone makes extensive use of dial colours and textures, with executions ranging from deep blue to salmon, green, amber, black and cream. The automatic Miyota 9039 powers most of the production and provides approximately 42 hours of power reserve. Several collaborations and limited editions subsequently enrich this base, including the customisable Blasonantes and, in 2024, a C-04 Date developed with Le Petit Poussoir.

Design & legibility: retro restraint and “feather” hands

The C-04 differs from Akrone’s technical models through a much more discreet search for elegance. The round case has short and simple lugs recalling certain Bauhaus designs and some post-war dress watches. The dial is generally constructed in several areas: a centre that may receive sunray brushing, lacquer or another finish, followed by a more grained or textured periphery carrying the minute track. Four applied metal markers occupy 12, 3, 6 and 9 o’clock on many variations, while the other positions are indicated more discreetly. The so-called “feather” hands are the most immediately recognisable distinguishing feature of the C-04. Their openworked design at the base recalls the nib of a fountain pen and reinforces the connection with French elegance claimed by the collection. The original C-04 has neither a date nor substantial luminous material, a choice consistent with its role as a city watch. Changes in reflected light therefore become more important than night-time reading: domed crystal, faceted markers and grained, sunburst or smoked dials substantially alter its appearance depending on wrist angle.

Case, bracelet and comfort: 38.5 mm for a versatile city watch

The original C-04 case measures 38.5 mm in diameter, approximately 43.8 mm in length and around 11 mm thick including the domed crystal. Its 20 mm lug width remains sufficiently standard for a wide range of straps. The 316L stainless steel mainly receives a polished finish on early versions, reinforcing their dress-oriented direction, although certain later series make greater use of brushing. The domed sapphire crystal is an important element of the design: it reproduces the appearance of vintage acrylic while offering significantly better scratch resistance. The approximately 43.8 mm length allows the C-04 to remain especially compact despite its large dial opening. Classical versions are frequently paired with a steel Milanese bracelet equipped with a quick-change system and double-security clasp. The fine mesh follows the wrist easily and strengthens the retro character. Collaborations also use French leather or bull calf. Weight can remain around sixty grams on lighter configurations. Water resistance of 5 ATM, or 50 metres, nevertheless corresponds more to an everyday watch than to one intended for regular swimming.

Movement: the Miyota 9039 as the principal mechanical base

Most C-04 watches use the Miyota 9039, a Japanese automatic mechanical calibre belonging to Citizen Miyota’s 9000 series. It operates at 28,800 vibrations per hour, or 4 Hz, allows manual winding and hacking seconds and provides approximately 42 hours of power reserve. The choice of the 9039 is particularly coherent with the C-04 because it is a no-date movement, allowing Akrone to retain a perfectly symmetrical dial without adding an unnecessary crown position associated with a phantom date. The transparent caseback allows the movement and especially an Akrone-modified oscillating weight to be viewed. The Miyota 9039 gives the C-04 slim, robust automatic mechanics that remain comparatively straightforward to service. Its restrained thickness also contributes to the reasonable profile of the case. Akrone inspects and regulates the watches in its Nantes workshop, although the final tolerance is not accompanied by independent chronometer certification. The 2024 C-04 Date forms an interesting exception: the commercial sheets for this collaboration specify a Miyota 9019 fitted with the calendar required to power the new date aperture on the dial.

Chronological milestones and main models (2021–2025)

(2021) Akrone C-04 Amber Textured Dial:

The Amber variation belongs to the first C-04 watches offered around the launch of the collection and immediately illustrates the importance Akrone places on dial treatment. The Akrone C-04 Amber reference not communicated uses a polished 38.5 mm 316L stainless-steel case, approximately 43.8 mm long and around 11 mm thick. Its amber dial combines several textures, notably grained areas and brushing or sunray effects that substantially alter the colour depending on lighting. The crystal is domed sapphire and the transparent caseback reveals the automatic Miyota 9039 together with its customised oscillating weight. This movement operates at 28,800 vibrations per hour and provides approximately 42 hours of power reserve. Water resistance is 50 metres. A steel Milanese bracelet completes the original presentation and contributes to the retro character. Above all, this version demonstrates that the C-04 was conceived as a platform where colour and texture become almost as important as the mechanics themselves.

(2021) Akrone C-04 Blasonantes Hand-Engraved Gold Applique:

The Blasonantes collaboration with engraver Thomas Brac de La Perrière transforms the C-04 into a customisable object and moves the collection closer to a métiers d’art approach. The Akrone C-04 Blasonantes reference not communicated retains the 38.5 mm 316L stainless-steel case and approximately 11 mm thickness, domed sapphire crystal, feather hands and automatic Miyota 9039 movement. Its central feature, however, is an 18-carat gold applique, white or yellow according to choice, cut and then engraved by hand. It may represent a family coat of arms, initials, a professional symbol, animal, personal sign or another motif requested by the owner. The series is limited to 100 watches, although every piece can be considered different because of this personalisation. The movement retains approximately 42 hours of power reserve and the case remains water-resistant to 50 metres. This series demonstrates that the visual simplicity of the C-04 dial also provides an interesting base for special or bespoke projects.

(2022) Akrone C-04 Kobalt Anniversary Blue:

The Kobalt uses a deep blue tone and is one of the C-04 series most readily identifiable on the pre-owned market. The Akrone C-04 Kobalt reference not communicated is documented as a limited edition of 100 pieces and retains the collection’s 38.5 mm architecture. The case remains stainless steel and the crystal domed sapphire. The blue Kobalt dial plays with reflections and retains the highly restrained marker arrangement together with the characteristic feather hands. The automatic Miyota 9039 operates at 28,800 vibrations per hour and provides approximately 42 hours of power reserve. No date aperture interrupts the symmetry of the dial. Water resistance remains 5 ATM and the Milanese bracelet is especially coherent with the retro design of the watch. This edition mainly offers greater collector interest than permanent colours because of its limited production and its connection with the early history of the C-04 collection.

(2023) Akrone C-04 Gold Eye Black and Gold:

Gold Eye demonstrates how substantially the personality of the C-04 can change without altering its overall architecture. The Akrone C-04 Gold Eye reference not communicated combines a black lacquered central medallion with a brushed outer area using gold or salmon tones. This two-part construction emphasises differences in dial texture and strengthens the reflections beneath the domed sapphire crystal. The polished stainless-steel case retains a diameter of 38.5 mm and approximately 11 mm thickness with 50 metres of water resistance. Feather hands and applied metal markers preserve the identity of the collection. The automatic movement remains the Miyota 9039, visible through the caseback and providing approximately 42 hours of power reserve. A Milanese bracelet gives the complete watch a typically retro appearance and can be replaced quickly thanks to the fitted release system. Gold Eye is highly representative of the period in which Akrone multiplies dial colours and treatments without modifying the proven technical base of the C-04.

(2023) Akrone C-04 Iris Kaktus Green Textured:

The Iris family develops the surface treatment further and later serves as an aesthetic starting point for several collaborations. The Akrone C-04 Iris Kaktus reference not communicated retains the 38.5 mm steel case, domed sapphire crystal and three-hand no-date construction but receives a strongly textured green dial. The surface relief changes the perception of colour under light and creates greater depth than a simple sunray dial. The principal markers remain applied at the cardinal positions and the feather hands retain their slim openworked form. The automatic Miyota 9039 operates at 4 Hz and provides approximately 42 hours of power reserve. The transparent back reveals the customised oscillating weight. Water resistance remains limited to 50 metres. This version can be worn on Milanese mesh or leather depending on configuration and illustrates the gradual transformation of the C-04 especially well: the watch remains technically simple, but every new dial treatment becomes a way of renewing its identity.

(2024) Akrone C-04 Date Smoked Blue Collaboration:

The collaboration with Le Petit Poussoir marks an important development because the date appears on the C-04 for the first time. The Akrone C-04 Date Smoked Blue reference not communicated retains a steel case approximately 38.5 mm wide, 43.8 mm long and 11 mm thick but adopts a more extensively satin-finished execution and a black bull-calf strap. The blue dial has a smoked and grained finish accompanied by a retro-inspired minute track. The date aperture is deliberately highlighted by a satin-finished eyelet rather than hidden within the dial. The commercial product sheet for this execution specifies an automatic Miyota 9019 operating at 28,800 vibrations per hour and providing approximately 42 hours of power reserve. The crystal remains domed sapphire and water resistance reaches 50 metres. This edition is limited to 33 pieces, like the two other colours in the triptych, and represents one of the last interpretations of this generation of C-04 before its withdrawal from the catalogue.

(2024) Akrone C-04 Date Smoked Brown Collaboration:

The smoked-brown variation uses exactly the same technical architecture but further emphasises the atmosphere of the 1960s and 1970s. The Akrone C-04 Date Smoked Brown reference not communicated has a 38.5 mm stainless-steel case, 43.8 mm length, approximately 11 mm thickness and 5 ATM water resistance. Its light-brown dial gradually darkens towards the edge, while the grained texture and lacquer cause the tones to change with the angle of incoming light. The date aperture receives the same satin-finished metal eyelet as the blue and red versions. Feather hands remain present and the strap is made from black bull calf with a curved pin buckle. The automatic Miyota 9019 provides approximately 42 hours of power reserve and operates at 4 Hz. Only 33 pieces are produced. This series is especially interesting for someone who appreciates the C-04 but wants a date function and a more exclusive presentation than the numerous dial variations of the regular collection.

Choosing the right version: dial, bracelet, date and everyday use

The first selection criterion is clearly the dial. Black, blue or cream variations remain easy to combine, whereas Amber, Gold Eye, Kaktus or salmon executions make the watch a more visible part of an outfit. The C-04 becomes most interesting when the dial texture genuinely corresponds to the owner’s personal taste. Mechanical differences between classical versions are minimal, so prioritising colour and cosmetic condition makes more sense than searching for a theoretical technical hierarchy between variations.

The 38.5 mm format is one of the principal advantages of the watch. At only around 43.8 mm long, the C-04 remains easy to wear on a small wrist and does not give the impression of being a large watch despite the substantial dial opening. These proportions are particularly suitable for someone who considers 40 or 41 mm dress watches too physically present. The domed crystal does, however, bring total thickness to around 11 mm, a reasonable figure but greater than certain ultra-thin city watches.

Milanese mesh forms a strong part of the identity of the classical C-04. It creates a retro appearance, remains flexible and is easy to adjust, although it can appear shinier and dressier than leather. Bull-calf collaboration models or separately available French leather straps reduce this metallic effect. A brown or black leather strap can easily transform the C-04 into a considerably more classical and discreet watch. The 20 mm lug width simplifies changes and provides a broad choice of compatible straps without relying on proprietary construction.

The choice between a no-date C-04 and the rare C-04 Date mainly depends on everyday habits. The original display without a calendar is more symmetrical and gives greater prominence to dial textures, while the 2024 collaboration adds useful information without attempting to hide the aperture. The no-date version remains the most faithful to the minimalism that has characterised the C-04 since launch. Date models will appeal more to someone intending to wear the watch daily at the office and regularly consulting the calendar.

Finally, 50 metres of water resistance requires use consistent with a city watch. It is suitable for splashes and normal daily life when correctly maintained, but the C-04 has neither a screw-down crown nor dive-watch construction comparable with the C-02. The C-04 is most at home in the office, at meetings, during evenings out and on dressier occasions rather than during aquatic activities. On the pre-owned market, the condition of polished surfaces, domed sapphire, bracelet and regular operation of the movement should be checked. Other customers’ opinions are essential.

Conclusion

The Akrone C-04 is aimed at enthusiasts wanting to discover the most classical and urban side of the Nantes watch company. Its compact 38.5 mm case, domed crystal, feather hands and numerous textured dials allow it to retain a distinct identity despite a deliberately simple architecture. The Miyota 9039 prioritises robustness, slimness and ease of servicing, while the transparent caseback and customised oscillating weight add mechanical interest. Amber, Kobalt, Gold Eye, Iris and Fantôme variations allow very different personalities to be chosen without altering the fundamental qualities of the watch. Blasonantes editions introduce an artisanal and personalised dimension, while the 2024 Date triptych represents a rare functional development within the collection.
