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 SBGW257

The Grand Seiko SBGW257 is a platinum dress watch praised for its refined, subtle luxury and classic design. Reviewers highlight its 38mm diameter and 10.9mm thickness as near-perfect sizing for a dress watch. The watch features an 18k white gold dial with a sunray-brushed silver finish and gold hour markers, complemented by a refined application of the Grand Seiko wordmark. 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 Fleuss Mechanical Chronograph

Owners widely report a split on build quality, with some finding the Spinnaker Fleuss Mechanical Chronograph's construction unimpressive due to issues like a poorly seated bezel and crooked indices, while others praise its robustness and aesthetic appeal. The unique dial features character hands and glowing eyes serving as subdials and a 24-hour indicator, though the chronograph function is limited to 60 minutes. On balance, the Spinnaker Fleuss Mechanical Chronograph elicits divided opinions on its build quality, with its artistic dial design being a notable, albeit polarizing, feature.

From video reviewers

The Spinnaker Googly Black's notable strength is its reported water-resistance of 300 fathoms or 550 metres. A weakness of this watch is its lume brightness, which is somewhat lacking. Reviewers disagree on the watch's ideal size, with one reviewer noting its slimmed-down design and the other mentioning its overall size and 26+ millimeter thickness.
