What people say

Owners + reviewers, side by side

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

Longines FLAGSHIP CLASSIC

Owners praise the Longines FLAGSHIP CLASSIC as a beautiful, classy dress watch with deep brand heritage, suitable for special occasions. One owner noted the stock strap appears narrow due to the lug design, making spring bars visible. The Longines FLAGSHIP CLASSIC reissue is considered a fantastic deal at $700, especially after a recent official Longines service and dial replacement, presenting it as a like-new watch. However, its lack of patina may disappoint collectors who value "character" from wear and scratches. Overall, owners rate the Longines FLAGSHIP CLASSIC highly for its aesthetic appeal and value proposition.

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.
