Yema Superman Steel CMM.10 Review: Features, Design, and Performance

The Yema Superman Steel CMM.10 represents one of the latest interpretations of Yema's legendary dive watch heritage. Since the Superman collection was introduced, it has become one of the brand's most iconic watch families, recognized for combining reliable diving performance with timeless French watchmaking design. 

Its reputation was further strengthened in 1967 when Yema patented its innovative bezel-lock mechanism, helping prevent accidental bezel movement during dives.

Today, the Superman collection has expanded into several distinct lines, including the Superman Tourbillon, Superman Skin Diver Full Lume, Superman Titanium, Superman Bronze, Superman Skin Diver, Superman Dato, Superman Gilt, Superman Slim, and Superman Classic. 

Each line offers its own interpretation of Superman's diving heritage while catering to different preferences in design, materials, and mechanical features.

Among these, the Superman Classic stands out for faithfully preserving the character of the original Superman while incorporating modern engineering. 

One of its signature models is the Yema Superman Steel CMM.10, a timepiece that combines the collection's iconic design with Yema's Manufacture CMM.10 movement and contemporary watchmaking innovations.

The Yema Superman Steel CMM.10: A Signature Model of the Superman Classic Line

The Yema Superman Steel CMM.10 is the signature model of the Superman Classic line, bringing together the collection's rich diving heritage and Yema's latest watchmaking innovations. 

This Yema Superman review takes a closer look at the Superman Steel CMM.10, exploring its timeless design, Manufacture CMM.10 caliber, premium construction, and the features that make it a compelling choice for collectors and enthusiasts seeking a modern mechanical dive watch with vintage-inspired character.

1. Timeless Design Inspired by the Original Superman

The Yema Superman Steel CMM.10 retains many of the design elements that have defined the Superman collection for decades. 

Its slim "skin diver" profile, signature crown-lock mechanism, pointed lugs, crown guards, and raised sapphire crystal preserve the vintage appearance of the original model while maintaining its identity as a professional dive watch. 

While honoring its heritage, the watch also introduces more contemporary proportions. The 39 mm stainless steel case, 47 mm lug-to-lug distance, 10.5 mm thickness, and 19 mm lug width create a balanced profile that offers excellent wrist comfort without sacrificing the bold appearance expected from a professional dive watch.

2. Durable Construction for Everyday Wear and Diving

Built with a vertically brushed 316L stainless steel case complemented by polished chamfers, the watch offers an elegant yet rugged appearance. 

The watch is protected by a 2.20 mm double-domed sapphire crystal that offers excellent scratch resistance while reinforcing its vintage-inspired appearance.

Its unidirectional rotating diving bezel features a polished ceramic insert with 0-to-60-minute graduations for precise dive timing. Yema also retains its patented bezel-lock mechanism, which helps keep the bezel securely in place during underwater use. 

Complementing these features are the screw-down crown with the embossed Yema logo and an impressive water resistance rating of 300 meters, making the watch suitable for serious diving activities.

3. Excellent Readability in Various Conditions

The black lacquered dial creates a clean and symmetrical appearance that improves legibility. White printed hour markers and polished hands stand out clearly against the dark background, while Super-LumiNova BGW9 Grade A applied to the hands, markers, and bezel ensures excellent visibility in low-light environments. 

The luminous bezel marker and arrow-shaped minute hand also help divers monitor elapsed dive time more easily.

4. Manufacture CMM.10 Caliber with Modern Performance

One of the most significant upgrades in this model is the introduction of Yema's Manufacture CMM.10 caliber. Developed entirely in-house, this movement reflects the brand's continued investment in advanced French watchmaking while delivering improved precision and overall performance.

The CMM.10 belongs to Yema's Manufacture movement family, which was introduced as part of the brand's effort to strengthen its in-house production capabilities. 

The name Calibre Manufacture Morteau (CMM) highlights its local origins, as the movement's mainplates and bridges are manufactured by Yema, while all components are produced within a 72-kilometer radius of Morteau before being assembled at the brand's workshops in the same region. 

To further enhance reliability and accuracy, the movement also incorporates Swiss regulating organs alongside Yema's in-house manufacturing expertise.

Announced in 2024, the CMM.10 was designed entirely from the ground up as a three-hand automatic caliber. Operating at 28,800 vibrations per hour (4 Hz), it delivers chronometric precision together with an impressive power reserve of approximately 70 hours. 

The movement can also be admired through the transparent sapphire caseback, allowing wearers to appreciate both its mechanical architecture and Yema's commitment to combining traditional craftsmanship with modern engineering.

5. Comfortable Bracelet with Functional Details

This Yema Superman watch is paired with the reissued Scales Slim bracelet, inspired by Yema's iconic bracelet design from the 1960s. Made from brushed 316L stainless steel, it complements the case while providing a cohesive vintage-inspired look. 

The folding clasp features an embossed Yema logo and includes a diver's extension, allowing the bracelet to be quickly adjusted when worn over a diving suit without sacrificing comfort during everyday use.

6. A Balance Between Heritage and Contemporary Watchmaking

The Yema Superman Steel CMM.10 successfully combines the design heritage of the original Superman with modern manufacturing and improved mechanical performance.

From its classic case profile and patented bezel-lock mechanism to its in-house Manufacture movement, this model demonstrates how Yema continues to preserve the character of one of its most iconic dive watches while incorporating contemporary watchmaking innovations.

Final Thoughts

The Yema Superman Steel CMM.10 demonstrates how a classic dive watch can evolve without losing the identity that made it iconic. By preserving the signature design elements of the original Superman while introducing the Manufacture CMM.10 caliber and refined modern engineering, Yema has successfully created a timepiece that respects its heritage while meeting the expectations of today's watch enthusiasts.

Beyond its vintage-inspired appearance, the watch offers a well-balanced combination of durability, precision, and everyday practicality. Features such as the patented bezel-lock mechanism, 300-meter water resistance, high-quality stainless steel construction, and comfortable Scales Slim bracelet make it suitable for both professional diving and daily wear.

Whether you appreciate heritage-inspired dive watches, value the craftsmanship of an in-house movement, or simply want a versatile mechanical timepiece, the Yema Superman Steel CMM.10 is a compelling choice within the Superman Classic line. It represents Yema's continued dedication to French watchmaking while proving that timeless design and modern performance can exist in a single watch.
