What people say

Owners + reviewers, side by side

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

Yema Skin Diver Slim CMM.20

Owners and reviewers widely praise the Yema Skin Diver Slim CMM.20 for its balanced 39mm case, vintage aesthetic, and unique champagne dial. The proprietary CMM.20 micro-rotor movement is a notable feature, though some owners report potential QC issues including erratic timegrapher readings and second-hand stutter. The lume is described as subdued, and while some find the "dragon scale" bracelet beautiful, others consider it generic. The price point is a hurdle for some, and the stamped clasp quality is considered subpar by one reviewer, with a gap noted by an owner. The lack of hacking seconds is flagged as a drawback at its price. Overall, owners and reviewers rate the Yema Skin Diver Slim CMM.20 highly for its vintage charm and balanced wearability.

Zelos Skyraider 40 Skeleton

The Zelos Skyraider 40 Skeleton is noted for its skeletonized dial and the use of BGW9 and C3 Super-LumiNova for legibility. It is powered by a manual-wind ETA 6498 movement, offering a 44-hour power reserve. On balance, the Zelos Skyraider 40 Skeleton is seen as a cool-looking option, though availability is a factor.
