Yema Superman Dato CMM.10 Review: A Fresh Take on the Superman Collection

Since its founding in 1948, Yema has built a strong reputation for creating watches that combine practical functionality with distinctive design. The brand’s identity was shaped by Henry-Louis Belmont, a trained watchmaker from the National Watchmaking School of Besançon who later became known for his innovative approach to watch manufacturing.  

From diving and motorsport to military applications, Yema has consistently explored watch designs that prioritize functionality and durability. This heritage eventually shaped the Superman collection, which became closely associated with the brand’s approach to professional tool watches and its distinctive bezel-lock mechanism.

The latest generation continues this legacy through the Yema Superman Dato CMM.10, combining the familiar character of the Superman collection with a redesigned case, modern materials, and Yema’s Manufacture movement. Its combination of French watch craftsmanship, chronometric performance, and practical dive-watch features gives the model a distinctive position within the brand’s current lineup.

So, what makes the Yema Superman Dato CMM.10 stand out from its predecessors? Read on to explore its heritage, design, movement, specifications, and the details that define this modern interpretation of Yema’s iconic dive watch.

A Bold Reinvention in the Superman Collection: Yema Superman Dato

The Yema Superman Dato represents a new chapter for one of Yema’s most recognizable dive-watch families. While the collection has long been associated with its distinctive bezel-lock system, screw-down crown, and strong underwater capabilities, the latest generation introduces a more contemporary interpretation without abandoning the characteristics that define the Superman name.

One of the most noticeable changes comes through the redesigned case. Yema replaces the traditional straight-lug profile with curved lugs and removes the crown guards, resulting in a cleaner silhouette with more fluid lines. The bezel-lock mechanism also receives a substantial update, moving beneath the bezel to create a more streamlined appearance while retaining its practical function.

The Superman Dato also brings a ceramic bezel into the collection, adding a more modern finish and greater resistance to everyday wear. Beneath the surface, the watch is equipped with Yema’s CMM.10 Manufacture caliber with a date complication. The movement combines a 70-hour power reserve with chronometric performance, giving the Superman Dato a technical foundation that goes beyond its visual appeal.

This latest evolution builds on a heritage that stretches back to 1967, when Yema introduced the original Superman with its patented bezel-lock mechanism. The design was developed to prevent unintended bezel movement during diving, helping establish the Superman as a serious French tool watch. Its reputation grew further through its association with demanding professional environments, including the French Air Force’s Search and Rescue swimmers in the 1970s.

Today, Yema continues to develop the Superman from its workshops in Morteau, France, where the brand has increasingly brought its manufacturing and watchmaking processes in-house. The Superman Dato reflects this broader direction: it retains the functional DNA that made the collection recognizable while introducing updated proportions, modern materials, and Yema’s latest-generation Manufacture movement. The result is a Superman that feels firmly connected to its past while moving confidently into the present.

Blending Yema’s dive-watch heritage with modern watchmaking, the Superman Dato CMM.10 Blue/White 39 mm presents a refined take on the brand’s legendary Superman collection. Its compact proportions, glossy blue-and-white dial, ceramic bezel, and Manufacture CMM.10 caliber give the watch a distinctive character rooted in both heritage and technical performance.

Through this Yema Superman Dato review, we will examine the watch from the inside out, covering its movement, dial, case, and bracelet. Read on to discover the complete specifications of the Yema Superman Dato CMM.10 Blue/White 39 mm.

1. The Mechanical Heart of the Superman Dato: CMM.10 Manufacture Caliber

At the heart of the Yema Superman Dato CMM.10 sits the CMM.10 Manufacture caliber, a mechanical self-winding movement developed by Yema. The name CMM comes from Calibre Manufacture Morteau, referring to the brand’s Morteau workshops in France, where the movement is designed, manufactured, assembled, and calibrated by Yema’s watchmakers.

The movement combines French manufacturing with selected Franco-Swiss components. While Yema produces the mainplate and bridges in Morteau, the regulating organs are manufactured in Switzerland. This approach allows the CMM.10 to combine locally produced components with specialized watchmaking expertise.

Technically, the caliber operates at a frequency of 28,800 vibrations per hour, or 4 Hz, and contains 27 jewels across its 208 components. Its architecture has also been designed with durability in mind. A central bridge brings several components together, helping reinforce the movement structure and improve its resistance to everyday shocks.

The balance wheel receives additional protection from a transversal bridge secured at two points. This construction helps keep the regulating organ firmly positioned while contributing to its resistance against impacts. The movement also uses Incabloc® double-cone shock absorbers to help protect the regulating mechanism from shocks coming from different directions.

For precision, the CMM.10 uses a Glucydur balance wheel paired with a Nivarox® hairspring. These components are designed to maintain stable performance against temperature variations and magnetic influences. The result is a movement rated for chronometric performance of -3/+5 seconds per day.

Another notable feature is its large barrel, which provides a 70-hour power reserve while maintaining the movement’s 4 Hz operating frequency. The barrel spring uses Nivaflex® alloy, selected for its mechanical strength, corrosion resistance, non-magnetic properties, and low thermal expansion.

The CMM.10 also features a bidirectional automatic winding system, allowing the oscillating weight to wind the mainspring as it moves with the wearer’s wrist. Combined with its robust construction and contemporary movement architecture, the caliber gives the Superman Dato CMM.10 a technical foundation that matches its tool-watch heritage.

2. A Glossy Blue-and-White Dial with Balanced Legibility

The Yema Superman Dato CMM.10 Blue/White 39 mm introduces a glossy lacquer dial that gives the watch a more polished and refined appearance. Its white surface creates a sharp contrast with the black IP-treated hands and hour markers, giving the dial a clean and contemporary visual identity.

Despite its refined appearance, the dial remains focused on legibility. The hour markers and hands are treated with Grade A Super-LumiNova, allowing the time to remain visible in low-light conditions. The luminous treatment extends to the bezel pip, reinforcing its functionality as a diving watch.

The date display is positioned at 6 o’clock, helping maintain visual symmetry across the dial. Rather than interrupting the upper portion of the display, the date window sits neatly within the lower section, preserving the balanced arrangement of the markers and hands.

Protecting the dial is a 2.20mm double-domed sapphire crystal with anti-reflective coating. Sapphire offers strong resistance to scratches, while the double-domed profile adds a subtle vintage-inspired character to the watch.

The combination of the lacquered dial, contrasting black elements, luminous treatment, and domed sapphire crystal gives the Superman Dato CMM.10 a neo-vintage personality without making the design feel dated.

3. A Streamlined Superman Case Built for the Water

Yema gives the Superman Dato CMM.10 a redesigned 316L stainless steel case measuring 39.5mm in diameter, 47mm from lug to lug, and 11.85mm thick. This relatively compact profile allows the watch to retain the presence of a traditional dive watch while offering a more streamlined feel on the wrist.

The case uses a vertical brushed finish across its main surfaces, complemented by polished chamfers. This contrast between brushed and polished sections adds definition to the case without taking away from its utilitarian character.

One of the most noticeable changes is the absence of conventional crown guards. Instead, the case presents a cleaner and more symmetrical silhouette, while the gently curved lugs follow the shape of the wrist more naturally. The non-drilled lugs further contribute to its contemporary appearance.

The bidirectional diving bezel features a blue zirconia ceramic insert with a 0-to-60 graduation. Ceramic provides a glossy finish while offering strong resistance to scratches, fading, corrosion, and UV exposure. Yema also integrates its signature bezel-lock system beneath the bezel rather than placing a visible clamp above it.

The concealed bezel-lock mechanism operates through a push-to-unlock system. The bezel remains locked during normal use and can be rotated in either direction when pressed down. Once released, it locks back into position. Together with the screw-down crown bearing an embossed Yema logo and 200-meter water resistance, these features reinforce the Superman Dato CMM.10’s credentials as a capable dive watch.

4. The Scales Slim Bracelet Brings a Modern Take on a Yema Classic

The Superman Dato CMM.10 is paired with a stainless steel Scales Slim bracelet, drawing inspiration from Yema’s original Scales bracelet from the 1960s. The design retains that historical connection while receiving a more streamlined treatment for contemporary wear.

With a 20mm lug width, the bracelet fits naturally with the compact case dimensions. Its links gradually taper toward the buckle, creating a slimmer profile as the bracelet moves down the wrist.

The bracelet is finished entirely with brushing, providing visual continuity with the brushed sections of the stainless steel case. This restrained finishing keeps the overall appearance cohesive while allowing the polished case chamfers to stand out.

Its slimmer construction also complements the 39.5mm case rather than making the watch feel unnecessarily bulky. The gently narrowing profile contributes to a more refined appearance and helps the bracelet follow the wrist comfortably.

Overall, the Scales Slim bracelet gives the Yema Superman Dato CMM.10 a balance between heritage and modern wearability. Combined with the compact case, contemporary bezel-lock system, and French-made CMM.10 caliber, it completes a dive watch that brings Yema’s historic Superman identity into a more refined modern format.

Conclusion

The Superman Dato CMM.10 shows how Yema can evolve a historic dive-watch design without losing the identity that made the Superman collection distinctive. The redesigned 39.5mm case, concealed bezel-lock mechanism, ceramic bezel, and 200-meter water resistance give it a contemporary profile, while the blue-and-white dial and Scales Slim bracelet add a more refined touch to its tool-watch character.

The CMM.10 Manufacture caliber further strengthens the watch with -3/+5 seconds per day chronometric performance and a 70-hour power reserve. With its modern movement architecture and continued French manufacturing in Morteau, the Superman Dato CMM.10 stands as a thoughtful update to Yema’s dive-watch legacy, offering a fresh direction while remaining recognizably Superman.
