What people say

Owners + reviewers, side by side

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

Vaer RS1 Rally Chronograph

Owners widely praise the Vaer RS1 Rally Chronograph for its legibility, with the red seconds hand noted as a standout feature. The watch is described as comfortable and good-looking, and many appreciate the inclusion of three quick-release straps. However, some owners report issues with the quality of the included steel bracelet, stating it does not seat flush on the case and that stock straps fit poorly. One owner also noted that the brand has faced criticism regarding perceived quality within its price range. Overall, owners rate the Vaer RS1 Rally Chronograph highly for its legibility and strap versatility, despite concerns about bracelet quality.

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.
