Maen Manhattan Ultra ThinvsYema Navygraf Marine Nationale 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.

The Yema Navygraf Marine Nationale CMM.10 is lauded for its vibrant blue dial and bezel, a slimmer 39mm case at 11mm thick, and its in-house CMM.10 caliber offering a 70-hour power reserve. Reviewers highlight the clean, legible dial, blue sapphire bezel insert, and competitive pricing under $2,000. However, the steel bracelet's clasp is noted by multiple sources as rattly and feeling slightly cheap, with one reviewer finding it difficult to open. Accuracy is reported within a range of +5/-3 seconds per day. Overall, reviewers praise the Yema Navygraf Marine Nationale CMM.10 for its attractive design and value proposition, tempered by minor concerns regarding the bracelet clasp.
