What people say

Owners + reviewers, side by side

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

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.

Zelos Swordfish 3

Owners widely praise the Zelos Swordfish 3 for its strong value, with reviewers highlighting the textured sandwich dial, Seiko NH35 movement, 200m water resistance, and surprisingly good bracelet. The titanium construction is noted for making the watch compact and comfortable, weighing 117g. Some owners find the dimensions fine on paper and based on experience with other models. One reviewer flagged that legibility can suffer in bright light and bracelet edges are sharp. Overall, owners and reviewers rate the Zelos Swordfish 3 highly for its incredible value and fun design, particularly with unique dial options.
