What people say

Owners + reviewers, side by side

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

Geckota Pioneer Special Edition

Owners widely praise the Geckota Pioneer for its retro-futuristic design and quality build at £349, with one owner noting excellent lume comparable to Panerai and a striking dial that shifts with light. The textured black honeycomb dial and 200m water resistance are also highlighted as strong points. However, some find the 14mm thickness a bit tall, and the NH 35 movement is considered unexciting by some. One owner points out that the thin cross-hair on the dial can be difficult to see from a distance. Overall, owners rate the Geckota Pioneer highly for its distinctive vintage space-age design and strong value proposition.

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.
