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 SLGH005

The Grand Seiko SLGH005 is widely praised for its stunning "White Birch" textured dial, exceptional finishing including mirror-polished indexes and Zaratsu polishing, and the innovative Caliber 9SA5 movement. Owners and reviewers consistently highlight the dial's texture and the elaborate, mirror-like indexes. The watch's 40mm stainless steel case is noted for its slender, sporty design and comfortable wearability, with some finding its size well-proportioned and its brushed and polished surfaces practical for hiding scratches. The 9SA5 movement is recognized for its 80-hour power reserve and 36,000 vph hi-beat frequency, though one owner found its finishing less impressive than other movement types in a similar price bracket. Some reviewers consider its price somewhat high relative to alternatives and desire a micro-adjustable bracelet. On balance, owners and reviewers rate the Grand Seiko SLGH005 highly for its exquisite dial and finishing, powered by an advanced high-beat movement.

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.
