What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

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.

Tissot PRX UFO Robot Grendizer 50th Anniversary

The Tissot PRX UFO Robot Grendizer 50th Anniversary is praised for its tasteful integration of anime elements onto the PRX design, featuring an engraved Grendizer bust on a sunburst blue dial with Super-Luminova, and is the first 40mm PRX to omit the date. Owners widely report huge demand, with all 1975 units selling out quickly. The packaging and watch box are described as "dope" and "insane," with one commenter stating the packing alone is "worth the buy." The watch retains the familiar 40mm case, Powermatic 80 movement with 80-hour power reserve, and integrated bracelet. Some find the Grendizer dial less appealing than the standard waffle dial, with one owner calling it "childish," while another considers it "the best PRX." The Grendizer graphic is less prominent in person than in photos, and the watch has a ghost date position. The Tissot PRX UFO Robot Grendizer 50th Anniversary retails for US$825 / CHF 795.
