What people say

Owners + reviewers, side by side

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

William Wood Dunkirk Watch

The William Wood Dunkirk Watch is noted for its unique dial design, inspired by engine order telegraphs and ship telegraphs, which some find emphasizes historical application over precise time-telling. Reviewers highlight its striking CuSn8 bronze case with red "pipes" and red lume, though one source found the red accents slightly jarring against the bronze. The 42mm watch, powered by a Sellita SW200 Top Grade movement, is limited to 600 pieces and priced around $5,200 USD. While legibility is maintained despite the unconventional dial, one owner finds the price difficult to justify. On balance, owners and reviewers acknowledge the William Wood Dunkirk Watch's distinctive historical inspiration and unique aesthetic, though some question its value proposition.

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.
