What people say

Owners + reviewers, side by side

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

Sugess MoonPhase Master S426

Owners widely praise the Sugess MoonPhase Master S426 for its sapphire crystal, well-finished stainless steel case, and the Seagull ST2153 automatic movement, which offers hacking and manual winding. The watch features a real moonphase complication, power reserve indicator, and date function, all for approximately $200. Reviewers highlight the guilloche dial detailing and the ST2155 movement, an ETA clone, noting its true moonphase complication. Overall, owners rate the Sugess MoonPhase Master S426 highly for its impressive complications and finishing at its price point.

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.
