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 Superman Slim CMM.20

Owners and reviewers praise the Yema Superman Slim CMM.20 for its appealing retro design, balanced 39mm case, and in-house CMM.20 micro-rotor movement, with some finding the fish scale bracelet attractive. Concerns exist regarding its $2500/€2,490 MSRP, with some owners questioning its value and noting the potential for QC issues or a "jittery" seconds hand attributed to the new movement. The bracelet's articulation and stamped clasp draw criticism, though some owners report it improves with wear. Overall, owners and reviewers appreciate the Yema Superman Slim CMM.20's vintage styling and unique micro-rotor movement, but its value proposition and some finishing details are points of contention.
