Seiko Presage Classic SeriesvsYema Skin Diver CMM.20

The Seiko Presage Classic Series is widely praised for its sublime dial and hand finishing, with textured dials inspired by Japanese silk fabrics and aesthetically pleasing curved hands. Owners and reviewers highlight the clean dials with applied indices and the robust elegance of the watches, noting the comfortable wearability of the cases, particularly the 36mm variants, and the practical 100m water resistance. The 6R movements provide a 72-hour power reserve, a notable improvement for the price point. However, the pin and collar bracelet system is criticized by one owner as subpar for the cost, and the quoted accuracy of the 6R55 movement is -15/+25 seconds per day, though one forum user reports better performance. The exhibition caseback's finish is described as entry-industrial, and the open-heart and 24-hour subdial configurations may not appeal to all.

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.
