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 SBGZ003

Grand Seiko SBGZ003 owners and reviewers widely praise its classic 38.5mm x 9.8mm dimensions and the meticulous perfection of its craft, with some calling it the sexiest Grand Seiko ever seen. The Spring Drive caliber 9R02 offers an 84-hour power reserve. Some find the dial's color off-putting, and the $57,000 price is a significant barrier for many. On balance, owners and reviewers rate the Grand Seiko SBGZ003 highly for its stunning "carved" dial and Micro Artist Studio finishing.

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.
