Yema Gives the Superman Bronze CMM.10 a Permanent Three-Dial Lineup

Yema’s Superman Bronze CMM.10 is no longer a limited-run curiosity.

The French watchmaker has added three permanent versions to the collection, giving the bronze-cased diver a broader identity beyond its first appearance in 2023. The update keeps the serious underwater credentials intact, but the smaller case and cleaner dials make it feel easier to wear day to day.

At a glance

A bronze diver in a more wearable size

The biggest shift is the move to a single 39mm case size.

Earlier Superman Bronze CMM.10 models were offered in both 39mm and 41mm formats, but the new permanent range settles on the smaller diameter. It’s a smart choice for a watch that already has plenty of presence thanks to its bronze case and dive-watch architecture.

The case measures 10.95mm thick, with a sapphire crystal adding a further 2.2mm.

Bronze remains a natural fit for the Superman brief, not only because of its nautical associations but because it develops a patina that changes with wear. That ageing process is part of the appeal, turning each case into something more personal over time.

Yema has also used a sapphire exhibition caseback, which helps reduce direct bronze contact against the wrist.

The watch keeps a proper tool-watch rating with 300 metres of water resistance, supported by a screw-down crown.

Lacquer dials soften the tool-watch character

The new dial options are brown, green and white, each finished in high-gloss lacquer.

Rather than leaning into bright sunray effects, the lacquer treatment gives the colours a smoother and slightly more restrained appearance. The green is the most immediately characterful of the three, with a forest tone that pairs especially well with the warmth of the bronze case.

Yema has also revised the marker layout.

The earlier mix of triangles, circles and rectangles has been replaced by lume-filled bar indexes, giving the dial a more uniform rhythm. The broader metallic surfaces let the gilt detailing stand out more clearly, echoed by the central arrow hands and logo.

The result is still recognisably a Superman, but it’s less overtly vintage-diver in execution.

The CMM.10 remains the heart of the watch

The movement is Yema’s Morteau Manufacture CMM.10, an automatic calibre that marked an important step for the brand when it appeared in the Superman Bronze line in 2023.

It runs at 28,800 vibrations per hour and delivers a 70-hour power reserve, wound by an openworked automatic rotor visible through the caseback.

Yema states an accuracy rate of -3/+5 seconds per day, placing the movement in chronometer-level territory without turning the watch into a purely technical exercise.

That combination is what makes this release interesting.

The Superman Bronze CMM.10 still reads as a capable diver, but the 39mm case, cleaner dial furniture and warmer material push it closer to an everyday sports watch. It’s the sort of piece that makes sense for someone who wants a dive watch with genuine utility, but doesn’t want it to look like equipment every time it leaves the water.

Details & Specifications

For Yema, this feels like a confident tightening of the Superman Bronze CMM.10 rather than a reinvention.

The watch now has a clearer place in the catalogue, balancing patina-friendly character, modern manufacture movement credentials and a size that should suit more wrists.
