What people say

Owners + reviewers, side by side

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

Longines LA GRANDE CLASSIQUE DE LONGINES

Owners widely praise LA GRANDE CLASSIQUE DE LONGINES for its extreme thinness, slim profile, and elegant, discreet design, making it exceptionally comfortable and almost unnoticeable on the wrist. The quartz version is noted for its reliability and "grab and go" convenience, while the automatic is considered a slim, dressy piece. Pre-owned prices for the quartz model range from $300 to $600, significantly lower than its $1650 retail. Some owners find the styling and Roman numerals appealing, and the bracelet is described as comfortable. One owner advises against gold plating due to potential wear, suggesting steel or solid gold instead. Discussions also arise regarding battery life in the quartz models, with one owner reporting a battery failure within months of replacement. Overall, owners rate LA GRANDE CLASSIQUE DE LONGINES highly for its elegant, thin design and comfortable wearability at its pre-owned price point.

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.
