Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the CWC (Cabot Watch Company) Arctic Radar Automatic Diver Watch for its robust build, comparing its toughness to that of the Marathon GSAR, and appreciate its preferred aesthetic and smooth bezel action. One owner reports accuracy of +3 seconds per day. Some owners note fixed springbars as a potential drawback. On balance, owners rate the CWC (Cabot Watch Company) Arctic Radar Automatic Diver Watch highly for its cool factor and military connection, deeming it a very solid watch.
The Yema Skin Diver CMM.20 is lauded for its vintage aesthetic, 39.5mm case size, and well-proportioned handset with sharp indices. Owners praise its textured cream dial, French tool watch elegance, and the smooth winding feel of the in-house CMM.20 micro-rotor movement. The fully brushed bracelet with toolless micro-adjust clasp is considered Yema's best yet. Accuracy readings range from -3/+7 seconds per day to approximately 0 to -10 seconds per day. Some reviewers noted questionable finishing on a prototype's hour hand and a rattly, stamped clasp. The watch's pricing has been questioned by some due to brand QC reputation, and its extended lug-to-lug may challenge smaller wrists. On balance, owners and reviewers appreciate the Yema Skin Diver CMM.20 for its vintage styling and improved bracelet design at its price point.
The sapphire bezel insert and in-house CMM.20 movement are noted strengths. Reviewers questioned the value proposition compared to other Yema models.
