Longines RECORDvsYema Skin Diver CMM.20

Owners and reviewers widely praise the Longines RECORD for its COSC-certified L888.4 movement, often noting excellent timekeeping with results ranging from 0 to +2 seconds per day, and some seeing as poor as -5 or +5 seconds per day. The watch is frequently commended for its elegant and clean design, comfortable and thin case profile, and overall value. Specific praise is given to the sunburst silver dial with applied numerals, sharp blue hands, and Calatrava-style case. Drawbacks noted include the 30m water resistance, lack of micro-adjustment on the bracelet, and a lug-to-lug measurement that some find long for smaller wrists. One owner also felt it might not retain value as well as other brands. Overall, owners and reviewers rate the Longines RECORD highly for its COSC-certified movement and elegant, thin design at a competitive price point.

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.
