Tissot PRX UFO Robot Grendizer 50th AnniversaryvsYema Yachtingraf Croisière Meca-Quartz

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 praise the Yema Yachtingraf Croisière Meca-Quartz for its attractive design, historical significance, and comfortable 38.5mm size, with some appreciating its meca-quartz movement. The watch features a hesalite crystal and Seiko VK63 movement, measuring 10.3mm thin and 46mm lug to lug. Some owners note sharp edges on the case and a strap that feels cheap, though others find the strap acceptable and consider it a great summer watch. Opinions are split on the necessity of the 24-hour subdial, and concerns have been raised about the price and customer support. On balance, owners rate the Yema Yachtingraf Croisière Meca-Quartz highly for its appealing vintage-inspired look and accessible price point.
