Tissot PRX UFO Robot Grendizer 50th AnniversaryvsWolbrook Skindiver WT Professional

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.

The Wolbrook Skindiver WT Professional is praised by owners for its straightforward design, retro aesthetic, and comfortable Beads of Rice bracelet with ample micro-adjustments. Reviewers and owners highlight its beautiful two-tone color, bold green dial, and box sapphire crystal with anti-reflective coating. Accuracy figures vary, with one source stating the Miyota 8315 movement is adjusted in France to ±15 seconds per day, while another owner notes it as a mecaquartz with good accuracy for its price. Some owners find the 40mm case wears smaller than expected, though one noted it felt larger. Feedback on the movement is mixed, with some preferring the Miyota 8315 over the 8215, and one commenter suggesting a Sellita SW200 would be more appropriate for the price. One reviewer expressed disappointment with mismatched hand and lume colors, poor lume performance, bezel wobble, and a high-sitting strap.
