Maen Manhattan Ultra ThinvsGrand Seiko SBGZ003

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.

Grand Seiko SBGZ003 owners and reviewers widely praise its classic 38.5mm x 9.8mm dimensions and the meticulous perfection of its craft, with some calling it the sexiest Grand Seiko ever seen. The Spring Drive caliber 9R02 offers an 84-hour power reserve. Some find the dial's color off-putting, and the $57,000 price is a significant barrier for many. On balance, owners and reviewers rate the Grand Seiko SBGZ003 highly for its stunning "carved" dial and Micro Artist Studio finishing.
