What people say

Owners + reviewers, side by side

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

CWC SBS 1987 Aged Special

Owners widely praise the CWC SBS 1987 Aged Special for its rugged build and military heritage, with some finding its quality comparable to higher-end watches. A reviewer notes the 41mm PVD-coated watch features a bright SuperLuminova dial. One owner reports a bit of play in the 60-click bezel, present from new, alongside minor wear on the PVD coating and bezel insert. On balance, owners rate the CWC SBS 1987 Aged Special highly for its rugged build and military heritage, despite some questioning its value at £700.

Yema Skin Diver CMM.20

Owners and reviewers widely praise the Yema Skin Diver CMM.20 for its vintage aesthetic, 39mm-39.5mm case size, and the in-house CMM.20 micro-rotor movement. The watch features a textured cream dial, sharp applied indices, and a satisfyingly over-engineered push-to-turn bi-directional bezel. The fully brushed bracelet with toolless micro-adjust clasp is highlighted as a significant improvement, though some note its extended lug-to-lug may challenge smaller wrists. Accuracy figures range from -3/+7 seconds per day to erratic results between 0 and -10 seconds per day, with a 70-hour power reserve. Some owners express concerns about the brand's QC reputation and the micro-rotor movement's performance, while one reviewer noted questionable finishing on a prototype's hour hand and a rattly clasp. Overall, owners and reviewers rate the Yema Skin Diver CMM.20 highly for its vintage styling and improved bracelet at the price.

From video reviewers

The sapphire bezel insert and in-house CMM.20 movement are noted strengths. Reviewers questioned the value proposition compared to other Yema models.
