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.

Longines HYDROCONQUEST MESH

Owners widely praise the Longines HYDROCONQUEST MESH for its eye-catching dial colors and impressive fit and finish at its price point, with some noting a well-regulated movement losing around 2 seconds per day and others seeing accuracy within COSC specifications. The tapered mesh bracelet is described as a clever execution with emphasized adjustability, offering a neat feature for wrist swelling. However, some owners criticize the bracelet's clasp for lacking on-the-fly micro-adjustments and the potential for pinching, while winding the screw-down crown is considered inconvenient by some. The lume is a point of contention, with one owner finding it disappointing and fading quickly, while another reports it as strong and long-lasting. Overall, owners rate the Longines HYDROCONQUEST MESH highly for its competitive pricing and versatile, modern retro aesthetic.
