Since its re-introduction in 2018, the Yema Superman dive watch has served as a flagship within the brand’s catalog. If you’ve handled one in person, you’ll know that it’s the kind of watch that really nails the vintage diver vibes. But there was always room for improvement, which Yema never shied away from in the past. Now, Yema has announced a completely re-imagined version of the Superman with aesthetic design changes and a big update under the hood that slims things down. Introducing the new Yema Superman Slim with the in-house CMM.20 micro-rotor movement.
I’ll admit that the Yema Superman was always kind of a watch that slipped my mind. The designs seemed cool enough and we have a diverse range of options within the collection … even a GMT. But it never really stuck for me. Yema’s integration of the CMM.20 micro-rotor movement might be something that sways potential buyers like me. It shows a commitment to refining the model long term, rather than simply banging out tons of different colorways or limited editions year after year. I’m even noticing that the bezel design has been simplified (markings for only the first 15 minutes). It’s almost like a dressier version of the watch, with new polished bevels on the case sides, curved lugs that flow better with the bracelet, and a 2mm domed crystal. All told, the watch is 11.8mm thick with the latest movement upgrade.
It still looks like a Yema Superman, though. You still get the characteristic bezel lock system that works directly with the screw-down crown. But then there’s the movement, the CMM.20 that was first debuted with Yema’s Wristmaster models. Yema’s got their hands in everything, with components made right in Morteau or sourced from Swiss and French suppliers within a 72km radius. Now, what sets this movement apart is its winding system. It’s got a micro-rotor made of tungsten, riding on ball bearings. This setup shaves off about 1mm in thickness compared to your standard SW200 or 2824, keeping things sleek and slim. Running at a smooth 4Hz frequency, it packs a solid 70-hour power reserve. It’s presented in a sleek blackened galvanic finish, giving it a bold and modern look. Plus, you get a reported accuracy ranging from -3 to +7 seconds per day.

The new Yema Superman Slim CMM.20 makes for one heck of an upgrade. To me, it’s a little more universally appealing and a part of that just stems from the watch now looking a little more upscale in its design. Hopefully we can get one of these in for review. The watch will be available for pre-order starting February 20th with the first 100 pieces set to be delivered in May. Check out more on Yema’s official site.
