What people say

Owners + reviewers, side by side

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

Citizen Promaster Sikorsky

The Citizen Promaster Sikorsky is a large 46mm watch honoring the S-92 helicopter, featuring a busy dial with red, white, blue, and yellow accents, and helicopter blade-shaped hands. It houses a solar-powered U680 movement with atomic time syncing. On balance, owners find the Citizen Promaster Sikorsky to be a unique, albeit cluttered, limited edition timepiece.

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.
