What people say

Owners + reviewers, side by side

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

Pinion Pure Steel

Owners widely praise the Pinion Pure Steel's balanced 38mm case size and 44mm lug-to-lug, fitting most wrists well. The dial is described as clear and essential, though reviewers note the lack of a minute track makes precise minute setting difficult. Accuracy is regulated in-house to +/- 5 to +/- 15 seconds per day. Some commenters found the white straps on featured watches to look "horrible." Overall, owners and reviewers appreciate the Pinion Pure Steel for its well-proportioned case and essential dial design.

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.
