What people say

Owners + reviewers, side by side

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

Ferro Time Master 70

The Ferro Time Master 70 is praised for its distinctive 1970s-inspired polygon case and visually striking silver dial with orange accents and unique lume colors. Owners appreciate the retro design with unique touches, clean dial, and lumed markers, along with the smooth winding of the Miyota 9039 movement. Its 39mm diameter, 10.4mm thickness, and 47mm lug-to-lug dimensions contribute to comfortable wearability, further enhanced by a well-executed faux-single link bracelet featuring a practical on-the-fly micro-adjustment clasp. On balance, owners and reviewers rate the Ferro Time Master 70 highly for its retro design and comfortable wearability.

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.
