What people say

Owners + reviewers, side by side

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

Geckota Classic Chronotimer

Owners widely praise the Geckota Classic Chronotimer for its appealing and distinct yet classic design, with many receiving compliments on its unique look. Enthusiasts highlight the hand-wound mechanical movement as a positive feature, noting the movements appear to be solid workhorses. Some owners find the Geckota Classic Chronotimer comfortable and fun to wear, appreciating its funky aesthetic and how well it contrasts with different straps. However, one owner reports the Chronotimer wears large on smaller wrists. Overall, owners rate the Geckota Classic Chronotimer highly for its beautiful and distinct design that garners frequent compliments.

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.
