Tissot PRX UFO Robot Grendizer 50th AnniversaryvsTimefactors PRS-38

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 Timefactors PRS is praised by owners for its 40mm case size, which fits smaller wrists well, and its value at $671 USD. One owner finds the cream dial with blued hands more visually interesting than the black dial. On balance, owners rate the Timefactors PRS highly for its wearability and value.
