What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Christopher Ward Twelve X Black Shadow

Owners and reviewers widely praise the Christopher Ward Twelve X Black Shadow for its exceptional titanium finishing, dynamic case design, and skeletonized COSC-certified SH21 movement with a 120-hour power reserve. Some owners note sharp edges on bracelet links and unfinished interior clasp surfaces, while reviewers mention legibility issues common to skeletonized watches and a thickness of 12.3mm making it feel chunkier than other models. On balance, owners and reviewers rate the Christopher Ward Twelve X Black Shadow highly for its impressive in-house movement and titanium finishing at its price point.

Yema Superman Steel CMM.10

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.

From video reviewers

The Yema Steel features an in-house movement with a micro-rotor, one of the most beautiful at this price point. The watch's clasp feels a bit thin, which is a notable drawback. Reviewers disagree on the movement's power reserve, with one reviewer noting a 42-hour reserve and the other not mentioning power reserve at all.
