Yema Superman Steel CMM.10vsYema YEMA x Silberstein Marine 2 CMM.20 Limited Edition

Owners widely praise the Yema Superman Steel CMM.10 for its refined casework, including polished lug bevels and an elegant crown guard, and its comfortable 39mm x 10.5mm dimensions. The glossy black lacquer dial and bezel insert are noted for adding depth, and the in-house CMM.10 movement is reported to be accurate, with one owner observing a loss of only 2 seconds over 2 days. The scales bracelet is described as gorgeous and nearly invisible on the wrist, though some find its polished center links too flashy. One reviewer flagged the signature bezel lock mechanism as flimsy and inconvenient. The CMM.10 automatic movement offers a 70-hour power reserve and is regulated to within +5/-3 seconds per day. On balance, owners and reviewers rate the Yema Superman Steel CMM.10 highly for its refined finishing and comfortable wearability at its price point.

The YEMA x Silberstein Marine 2 CMM.20 Limited Edition is noted for its slim 39mm case and in-house CMM.20 micro-rotor movement, offering 300 meters of water resistance and a 70-hour power reserve. Reviewers highlight the watch's thin profile and flowing case design, as well as its black lacquered enamel dial. However, the bezel's lack of numbers is considered a practical drawback, and one reviewer noted the audible spin of the micro-rotor, which was unexpected given the €1,990 price for the 200-piece limited edition. The included leather strap is also seen as less suited for the watch's dive capabilities. Overall, reviewers appreciate the YEMA x Silberstein Marine 2 CMM.20 Limited Edition for its slim design and in-house movement, though practical considerations regarding the bezel and strap are noted.
