What people say

Owners + reviewers, side by side

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

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.

Studio Underd0g Smoked Salmon

Owners widely praise the Studio Underd0g Smoked Salmon's clean, elegant design and unique appeal, with some appreciating its simple, unbranded look and others noting its conversation-starting ability. The watch features a two-layered, metallic salmon-skin-inspired dial housed in a 38.5mm stainless steel case. It is powered by a Swiss-made Sellita SW510 M MP b monopusher chronograph movement, with advertised accuracy of ±5 seconds per day. Some owners find the £1700/€1,800 price point high, and one owner noted a "raised glass fishbowl over the dial." Overall, owners rate the Studio Underd0g Smoked Salmon highly for its unique dial design and conversation-starting appeal.
