It is powered by the manual-wind Caliber 9S64 movement, offering a 72-hour power reserve and an accuracy rating of +5 to -3 seconds per day. The Grand Seiko SBGW257 is priced at €39,000. On balance, reviewers appreciate the Grand Seiko SBGW257 for its exquisite finishing and classic proportions, embodying a quiet luxury.

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.
