What people say

Owners + reviewers, side by side

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

Oris Big Crown Diamonds

Owners widely praise the Oris Big Crown Diamonds for its timeless design, vintage charm, and recognizable details like cathedral hands and the pointer date function. Reviewers highlight the stunning gradient dial and the "Bullseye" tuxedo dial as particularly beautiful. The 38mm case is considered versatile, and the watch offers remarkable value. However, some owners note the standard Sellita movement has a short power reserve and plain finishing, and the strap is not durable. A reviewer points out slightly imperfect Super-LumiNova printing on the hour numerals, and one owner finds the two-tone bracelet overly flashy. On balance, owners and reviewers rate the Oris Big Crown Diamonds highly for its unique design and value 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.
