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 Steel CMM.10

Owners widely praise the Yema Superman Steel CMM.10 for its refined casework, including polished lug bevels and an elegant crown guard, and its comfortable 39mm x 10.5mm dimensions. The glossy black lacquer dial and bezel insert are noted for adding depth, and the in-house CMM.10 movement is reported to be accurate, with one owner observing a loss of only 2 seconds over 2 days. The scales bracelet is described as gorgeous and nearly invisible on the wrist, though some find its polished center links too flashy. One reviewer flagged the signature bezel lock mechanism as flimsy and inconvenient. The CMM.10 automatic movement offers a 70-hour power reserve and is regulated to within +5/-3 seconds per day. On balance, owners and reviewers rate the Yema Superman Steel CMM.10 highly for its refined finishing and comfortable wearability at its price point.

From video reviewers

The Yema Steel features an in-house movement with a micro-rotor, one of the most beautiful at this price point. The watch's clasp feels a bit thin, which is a notable drawback. Reviewers disagree on the movement's power reserve, with one reviewer noting a 42-hour reserve and the other not mentioning power reserve at all.
