Maen Manhattan Ultra ThinvsYema Wristmaster Slim CMM.20

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.

The Yema Wristmaster Slim CMM.20 is widely praised for its compelling integrated bracelet design and comfortable 39mm wearability. Reviewers highlight its impressive value, featuring an in-house CMM.20 micro-rotor movement with a 70-hour power reserve, adjusted to -3/+7 seconds per day, all within a slim 9mm case. Some note the domed sapphire crystal can produce glare and the dial text is quite small. On balance, reviewers rate the Yema Wristmaster Slim CMM.20 highly for its integrated design and value proposition with a micro-rotor movement.
