Maen Manhattan Ultra ThinvsGrand Seiko SLGW005

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 Grand Seiko SLGW005 is lauded for its faithful recreation of the 1968 45GS, featuring a desirable double-signed dial and a beautifully finished case adhering to the Grammar of Design. It is powered by the new 9SA4 manual-winding, high-beat movement, offering an 80-hour power reserve and a mean daily rate of -3/+5 seconds. Owners consider it a "gloriously perfect" and "pure and elegant expression" of Grand Seiko's strengths, with one owner preferring its creamy dial over a more pronounced beige found on other models. Overall, owners and reviewers rate the Grand Seiko SLGW005 highly for its elegant design and impressive high-beat movement.
