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 SBGM245

Owners widely appreciate the Grand Seiko SBGM245 for its blend of sport and luxury, with one enthusiast highlighting its superior workmanship over quartz movements. However, opinions on its size vary, as one owner found the SBGM245 too large, preferring the comfort of a different variant. Overall, owners value the Grand Seiko SBGM245 for its refined craftsmanship, though its wearability is a point of personal preference.

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.
