The YEMA Superman Slim CMM.20 combines the brand’s signature dive-watch details with a 39 mm steel case measuring 9.95 mm thick and YEMA’s self-winding micro-rotor calibre. Its headline specifications include a stated 70-hour power reserve and 300 m water resistance. Those are manufacturer figures, not independently verified performance results.
What is the Superman Slim CMM.20?
It is a slimmer, redesigned take on YEMA’s Superman dive watch. The watch retains the Superman’s dive-oriented bezel and mechanical bezel-lock feature while using a 39 mm case and a micro-rotor movement. YEMA presents it as a sport watch that can also suit more formal styling; that is the brand’s positioning, not an independent assessment of how it wears.

Case, dial and dive-watch features
YEMA lists a 316L stainless-steel case with brushed surfaces and polished bevels. The case measures 39 mm across and 9.95 mm thick, with curved lugs and a 20 mm lug width. A 2.00 mm double-domed sapphire crystal covers the lacquered enamel dial.
The unidirectional dive bezel has a sapphire insert, 0–60 graduation and a luminous marker at 12 o’clock. YEMA says its mechanical bezel-lock design has been patented since 1967. The screw-down crown and listed 30 BAR / 300 m water resistance round out the core dive-watch specifications. These are product specifications; no independent dive test is established here.

CMM.20 micro-rotor movement
The watch uses YEMA’s Manufacture Morteau 20 (CMM.20), a self-winding micro-rotor calibre with a ball-bearing rotor. YEMA states a 70-hour power reserve and a maximum rate of −3/+7 seconds per day. Treat both figures as manufacturer specifications rather than independently measured results.

The listed bracelet is 316L stainless steel with a brushed finish. Its double-security folding clasp includes a diving extension. YEMA specifies 20 mm lugs, but that measurement alone does not confirm that a particular replacement bracelet or third-party strap will fit: check the case-end geometry and compatibility with the exact watch reference before buying.
What “Manufacture Française” means
YEMA says the dial text “MANUFACTURE FRANÇAISE” reflects the internalization of manufacturing for CMM calibre components and local production of cases. The company also describes working with local partners in France and Switzerland. These are YEMA’s statements about its manufacturing arrangements, not independent verification that every component originates in France.
Price and availability
YEMA’s collection listing showed a price of $2,790 and marked the watch “SOLD OUT.” That is a U.S.-dollar listing snapshot, not a guarantee of current price or stock. Check YEMA’s Superman collection for the live listing and confirm the applicable currency, taxes and availability for your region.

The clearest change is the combination of a 9.95 mm profile and the CMM.20 micro-rotor calibre in a 39 mm Superman case. The watch keeps recognizable dive-watch functions, including the bezel lock, while presenting a thinner format. Whether it is a better choice than another diver depends on a matched comparison of dimensions, movement, bracelet fit, price and other specifications; the available information does not establish that it outperforms a particular competitor.
