What people say

Owners + reviewers, side by side

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

Christopher Ward The Twelve 660

Christopher Ward The Twelve 660 owners and reviewers highlight its exceptionally thin 6.6mm case, achieved through a two-hand design, manual-wind movement, and 30m water resistance. The bracelet clasp, however, lacks micro-adjustments. Opinions are divided on the manual-wind nature and absence of a seconds hand, with some finding them unnecessary while others value the resulting slimness and winding experience. One user noted the logo as a drawback. Overall, the Christopher Ward The Twelve 660 is considered good value and well-made by the community, with its thinness being a primary draw.

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.
