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 SLGB001

The Grand Seiko SLGB001 is a limited edition platinum watch in the Evolution 9 collection, featuring a 37mm case and the new Calibre 9RB2 Spring Drive U.F.A. movement, rated to ±20 seconds per year. It has an "Ice Forest" dial with a deep blue hue and a silver seconds hand, but notably lacks lume. A criticism is the absence of a micro-adjustment clasp on its leather strap. Overall, reviewers highlight the watch's advanced movement and distinctive dial as key features.

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.
