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 SBGJ249

Grand Seiko SBGJ249 owners and reviewers widely praise its spectacular beauty, particularly the stunning wave dial that shifts color and exhibits an incredible texture. The watch is noted for its perfect proportions and "out of this world" finishing on the case, hands, and hour indices. It is powered by the Hi-Beat Caliber 9S86, a true GMT movement operating at 36,000vph. Accuracy is reported at -3 to +5 seconds per day, with one owner noting +3 seconds per day. The watch is offered at $6,800, which is considered outstanding value. A drawback flagged is its 3 bar water resistance. On balance, owners and reviewers rate the Grand Seiko SBGJ249 highly for its exceptional dial finishing and overall beauty at its price point.

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.
