Tissot PRX UFO Robot Grendizer 50th AnniversaryvsWolbrook Skindiver WT Chrono-Mecaquartz

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.

Owners widely praise the Wolbrook Skindiver WT for its handsome vintage aesthetic, authentic retro vibe, and value for money, often highlighting its legible dial, sapphire crystal, and drilled lugs. The worldtimer bezel and comfortable Beads of Rice bracelet also receive positive mentions. However, some owners report issues with hand color matching, lume quality, bezel wobble, and a high-sitting strap. One owner found the 40mm size wore larger than expected, while another was put off by the push-pull crown. The Miyota 8315 movement is considered less desirable than the 9 series by one owner, and the brand's warranty is not honored if the watch is sold or gifted. Overall, owners rate the Wolbrook Skindiver WT highly for its vintage personality and value, despite some noted build quality concerns.
