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 SLGB006

The Grand Seiko SLGB006 is praised for its stunning "Ice Forest at Dawn" textured dial and 37mm 18k yellow gold case, with some finding it gorgeous enough to wear even if they don't typically prefer gold watches. It houses the Spring Drive Calibre 9RB2 movement, noted for its "Ultra Fine Accuracy" of ±20 seconds per year and a 72-hour power reserve. However, the Grand Seiko SLGB006 is considered expensive by some, with a price of $43,600 or €44,700 for its limited production of 80 pieces, and one owner suggests alternatives offer a more refined feel. The watch lacks the Evolution 9 micro-adjustment system. Overall, owners and reviewers highlight the Grand Seiko SLGB006's striking dial and movement accuracy as its primary strengths, despite its high price point and limited availability.

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.
