What people say

Owners + reviewers, side by side

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

Geckota Pioneer Automatic

Owners widely praise the Geckota Pioneer Automatic for its retro-futuristic design, impressive lume, and unique dial finishing. The red dial variants are particularly favored for their brushed fumee appearance and vintage feel. Accuracy is noted as surprisingly good for an NH35 movement, though one owner reports +/- 20 seconds per day. The watch is considered a bargain by some at $259, while others find the $519 price for the NH35 movement in a 14mm thick case excessive. The 42mm cushion case is noted to wear large due to its lack of a prominent bezel. A minor phantom date position on the crown is reported, and the crystal is very reflective despite an anti-reflective coating. Some find the gold accents look a bit cheap, and one instance of a loose fleck of lume was observed. Overall, owners rate the Geckota Pioneer Automatic highly for its distinctive vintage aesthetic and value, particularly on sale.

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.
