What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Sternglas Hamburg Automatik

Owners praise the Sternglas Hamburg Automatik's handsome design and good build quality for the price. The watch features a gold PVD case and a matte blue dial with orange Super-LumiNova, and its 42mm diameter wears well due to a short lug-to-lug distance. The Miyota 8215 movement is accurate to -20/+40 seconds per day. On balance, reviewers and owners appreciate the Sternglas Hamburg Automatik for its unique design and value.

Grand Seiko SBGM221

Grand Seiko SBGM221 is widely praised for its exceptional dial finish, highly polished hands and indices, and elegant design. Owners consistently highlight the stunning craftsmanship, with specific mention of the up to 11 hand-polished facets on its rectangular markers. The reliable 9S66 movement is noted for its 72-hour power reserve and true GMT functionality, tested beyond Chronometer specifications. Some enthusiasts desire a bidirectional 24-hour bezel, which the Grand Seiko SBGM221 lacks, and its 13.7mm thickness and 19mm lug width are noted as potential limitations. On balance, owners rate the Grand Seiko SBGM221 highly for its exquisite finishing and elegant, comfortable design.

From video reviewers

The SBGM221 is praised for its value within the Grand Seiko lineup. The lug width is cited as a weakness.
