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 SBGH368

The Grand Seiko SBGH368 is praised for its aggressive styling and textured copper-pink dial, inspired by cherry blossoms. Reviewers highlight its 38mm 18k rose gold 62GS case, featuring Zaratsu polishing, as a standout element. The watch is powered by the Hi-Beat Caliber 9S85 movement, which is regulated to -3/+5 seconds per day and offers a 55-hour power reserve. It also features 100m water resistance. One reviewer notes that the brown crocodile strap, while handsome, would ideally be replaced with a water-resistant option given the watch's 100m water resistance. There is also a question raised about whether a movement with a longer power reserve could have been utilized. The Grand Seiko SBGH368 retails for $31,200. Overall, reviewers consider the Grand Seiko SBGH368 a favorite gold-cased Grand Seiko, with its rose gold case and cherry blossom dial described as an exceptional combination.

Spinnaker Dumas GMT

Owners praise the Spinnaker Dumas GMT's satisfying lume, including on the crown, and good finishing, with one owner finding it wears well on a 17cm wrist. The watch features a Seiko NH34A GMT movement and a blue gradient dial. Reviewers note its 44mm diameter and 209g weight on the bracelet make it unsuitable for smaller wrists.
