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 Navygraf CMM.10

Owners widely report quality control concerns and suspect craftsmanship with the Yema Navygraf, with one user noting crooked text. A reviewer praised the Slim CMM.20 Limited Edition for its stylish, slim profile and classy finishing on a black lacquered enamel dial, though the audible micro-rotor spinning at its price point was a surprise. On balance, the consensus is that while the Yema Navygraf offers a stylish design, potential buyers should be aware of reported quality control issues.
