Yema Skin Diver Review: Design, Movement, and Heritage

A strong connection to sports and tool watches has shaped Yema’s identity for decades, particularly through its timepieces made for demanding environments. Founded in 1948 by French watchmaker Henry-Louis Belmont, the brand has developed watches for divers, pilots, and racing drivers, building a reputation around functional mechanical designs with distinctive character.

Among its most recognizable creations, the Superman has earned a lasting reputation as a legendary French dive watch. Its history dates back to the 1960s, when Yema introduced dive watches designed around durability, underwater legibility, and practical features. This heritage continues today through collections that reinterpret the brand’s historic diving designs with contemporary materials and mechanical technology.

In this article, we will explore Yema’s Skin Diver heritage and take a closer look at two models selected by Gnomon Watches, including their designs, movements, and key specifications. Let's dive into the details and discover what makes these Yema Skin Diver watches worth a closer look.

Yema Skin Diver: Reviving the 1960s Skin Diver Heritage

Yema’s Skin Diver collection brings the character of the brand’s early diving watches into a contemporary setting. Its design takes cues from the skin divers produced during the 1960s, when Yema was building a reputation for practical tool watches designed for demanding environments. Rather than simply reproducing the look of those historical references, the collection combines familiar vintage details with modern materials and mechanical technology.

The story behind the Skin Diver is closely connected to Yema’s broader dive-watch heritage, particularly the Superman. Introduced in 1967, the Superman established a distinctive identity with its innovative bezel-lock system, screw-in crown, and strong water resistance. The model eventually became France’s first production dive watch rated to 300 meters, helping cement its reputation as a serious underwater instrument. These characteristics continue to influence YEMA’s approach to modern dive watches, including the Skin Diver line.

The collection also reflects Yema’s longstanding focus on watches built for real-world use. The brand was founded in 1948 by Henry-Louis Belmont, a French watchmaker known for developing watches aimed at activities such as diving, motorsports, and military expeditions. During the following decades, Yema expanded its presence internationally while developing watches for increasingly demanding environments. This history helps explain why the Skin Diver combines a relatively refined vintage appearance with specifications intended for practical use.

Modern manufacturing has given the Skin Diver another defining element through Yema’s Manufacture movements. The collection uses the CMM.20, a micro-rotor caliber developed as part of Yema’s renewed focus on French watchmaking. Its compact architecture allows the movement to fit within a slimmer case, while a transparent sapphire case back lets the wearer see the mechanism. The CMM.20 also represents a broader shift in Yema’s manufacturing strategy, with the brand increasing the production of movement components within and around its Morteau workshops.

Morteau itself plays an important role in the modern identity of Yema. Located in the French Jura region, the town has a long-established watchmaking tradition and serves as the home of Yema’s workshops. Since 2022, the brand has invested further in bringing more manufacturing processes in-house and working with specialized French and Swiss suppliers located within a 72km radius of Morteau. This approach culminated in the CMM series, whose name refers directly to the Calibre Manufacture Morteau and its local production philosophy.

With the Skin Diver, Yema therefore looks back to an important chapter of its diving history while moving the concept forward through contemporary watchmaking. The vintage-inspired case architecture, dive-oriented features, and modern CMM.20 movement create a connection between the brand’s 1960s skin divers and its current Manufacture ambitions. It is this combination of historical design language and modern French mechanical development that gives the Skin Diver collection its distinctive place within Yema’s current lineup.

Top 2 Yema Skin Diver Watches Selected by Gnomon Watches

With their vintage-inspired designs and modern mechanical features, Yema Skin Diver watches offer an appealing balance of heritage and contemporary watchmaking. Each model brings its own combination of materials, colors, and technical details to the collection, giving enthusiasts different ways to experience the brand’s take on the classic skin diver.

Below, we highlight two Yema Skin Diver watches selected by Gnomon Watches. Read on to explore their designs, specifications, and standout features.

1. Yema Skin Diver CMM.20 Beige

The vintage character of the 1960s comes through clearly in the case design, while its proportions give the Yema Skin Diver CMM.20 Beige watch a more contemporary presence. Measuring 39.5mm in diameter, 47mm from lug to lug, and 11.5mm thick, the case maintains a relatively slim profile for a mechanical dive watch. Its 316L stainless steel construction features vertical brushing across the main surfaces, complemented by polished bevels that add subtle contrast and definition.

A bidirectional diving bezel sits above the case and features a sapphire insert with a 0-to-60 graduation. Its push-to-unlock mechanism keeps the bezel securely in place when not in use, while pressing it down releases the lock and allows it to rotate. This modernized system removes the need for an external locking clamp, resulting in a cleaner silhouette while preserving the practical character expected from a dive watch. The screw-down crown also carries an embossed Yema logo and helps support the watch's 300m water resistance.

Under the 2.20mm double-domed sapphire crystal, the slightly brushed beige dial brings a warm, retro character to the design. Triangular hour markers are paired with Arabic numerals at 3, 6, 9, and 12 o'clock, creating a layout that remains easy to read at a glance. Polished steel surrounds the applied markers and hands, adding definition against the beige background, while the oversized markers and distinctive hand shapes reinforce its vintage-inspired appearance.

Visibility in low-light conditions comes from Super-LumiNova C3 Grade A applied generously to the hands and hour markers. The combination of luminous triangular indices and contrasting hands helps maintain clear time reading when the surrounding light is limited. Meanwhile, the anti-reflective coating on the sapphire crystal works alongside its double-domed profile to improve readability while contributing to the watch's classic appearance.

Powering the watch is the Micro-Rotor Caliber Manufacture Morteau 20, or CMM.20, which takes a different approach to achieving a thinner mechanical construction. Its tungsten micro-rotor winds the movement while occupying less vertical space than a conventional full-size rotor. This architecture helps keep the case at 11.5mm thick without sacrificing the 300m water resistance expected from a capable dive watch, while the exhibition case back provides a view of the movement in operation.

Completing the vintage-inspired design is a 20mm Scales Slim bracelet made from brushed 316L stainless steel. The bracelet follows the proportions of the case and tapers toward the clasp, while its slim construction is designed to sit comfortably on the wrist. A dive extension adds practicality, and the on-the-fly adjustment system allows the fit to be changed without tools. Together, these details give the watch a balance of 1960s-inspired aesthetics, modern mechanics, and everyday dive-watch functionality.

2. Yema Skin Diver Slim Bronze Green

Its slim profile gives the watch a balanced presence on the wrist without sacrificing the robust character expected from a dive watch. The bronze case has a compact 39mm diameter, a 47mm lug-to-lug length, and a 10mm thickness excluding the crystal, creating a relatively slender silhouette with a sturdy feel. Vintage-inspired details, including the unguarded crown and refined case finishing, further enhance its retro character, while polished bevels provide subtle contrast against the brushed surfaces.

The slim construction is made possible in part by the Micro-Rotor Caliber Manufacture Morteau 20, also known as the CMM.20. Instead of using a conventional full-size rotor, the movement relies on a tungsten micro-rotor mounted on ball bearings, allowing the winding mechanism to occupy less vertical space. This architecture helps Yema maintain a thinner case while retaining the mechanical functionality and 300m water resistance expected from a professional dive watch. An exhibition case back also offers a view of the movement and its micro-rotor mechanism.

Vintage cues continue across the front of the watch through its dark green sandblasted enamel dial, which features a matte finish. Golden applied markers and hands stand out against the subdued surface, while triangular indices and Arabic numerals at 3, 6, 9, and 12 o'clock provide a clear reading of the time. The 2.20mm double-domed sapphire crystal adds another period-inspired touch while providing modern durability. Super-LumiNova C1 Grade A enhances visibility when lighting conditions become less favorable.

The bronze case adds warmth to the design and will naturally develop a patina over time, giving each watch a progressively more individual appearance. A unidirectional diving bezel surrounds the dial, using a sapphire insert with 0-to-60 markers for dive timing. Its color is coordinated with the green dial, creating a cohesive look across the front of the watch. Featuring a screw-down design and embossed Yema branding, the crown helps reinforce the case’s ability to withstand water pressure down to 300 meters.

A 20mm FKM VITON® Scales rubber strap brings a more practical character to the wrist. Its flexible construction is designed to withstand demanding conditions, while the distinctive Scales relief pattern adds texture without overwhelming the vintage-inspired design. The strap is finished in a tone that complements the green dial and bezel, creating a unified appearance. A bronze buckle further ties the strap to the case and can develop its own patina as the material ages.

The combination of a slim case, micro-rotor movement, bronze construction, and vintage-inspired dive-watch details creates a distinctive interpretation of Yema's 1960s design heritage. Its proportions keep the watch relatively restrained on the wrist, while the 300m water resistance and functional bezel give it the capabilities expected from a serious dive watch. With its blend of French mechanical engineering, retro styling, and modern materials, the Yema Skin Diver Slim Bronze Green offers a distinctive option for enthusiasts seeking a watch with both character and technical depth.

Conclusion

Yema Skin Diver watches offer a thoughtful blend of historical character and contemporary watchmaking. Drawing inspiration from Yema’s 1960s skin divers and the legacy of the Superman, the collection retains the visual language of vintage dive watches while incorporating modern materials, reliable water resistance, and updated mechanical technology. The result is a range that feels rooted in the brand’s history without simply replicating its past designs.

The two models featured above showcase different interpretations of this approach. The Yema Skin Diver CMM.20 Beige combines a stainless steel case and warm beige dial with a slim Scales Slim bracelet, while the Yema Skin Diver Slim Bronze Green takes a more distinctive route with its bronze case, dark green dial, and FKM VITON® rubber strap. Both models share the CMM.20 micro-rotor caliber, 300m water resistance, and vintage-inspired proportions, yet their different materials and color combinations give each watch its own character.

Whether you appreciate the understated appeal of stainless steel or prefer the evolving character of bronze, these Yema Skin Diver models offer a modern way to experience Yema’s French dive-watch heritage. Their combination of vintage aesthetics, capable specifications, and Manufacture movement technology makes them noteworthy choices for enthusiasts looking beyond conventional contemporary dive watches.
