Maen Manhattan Ultra ThinvsYema Superman Steel CMM.10

The Maen Manhattan Ultra Thin is widely praised for its slim case, with reviewers noting a 6.9mm or 7.1mm thickness, and its elegant, vintage-inspired styling. Specific design elements highlighted include a Côtes de Genève or hammered "Tuscan" dial finish and an integrated bracelet. The hand-wound ETA Pesaux 7001 movement is noted for its role in achieving the thin profile, offering a 42-hour power reserve. However, the black text on the vertically striped dial can be difficult to read, and the integrated bracelet lacks a quick-release system. Some reviewers expressed a desire for a 38mm case size option. Overall, reviewers rate the Maen Manhattan Ultra Thin highly for its slim, elegant design and vintage aesthetic at its price point.

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.
