Tissot PRX UFO Robot Grendizer 50th AnniversaryvsYema Rallygraf 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 widely praise the Yema Rallygraf Meca-Quartz for its heritage reissue design, small and thin case, and good looks for the price, with some noting exceptional build quality, tactile pushers, and a substantial feel. However, the quartz movement's ticking smoothness and the 24-hour subdial, which functions as an AM/PM indicator rather than a totalizer, are points of criticism for some, leading to perceptions of it being overpriced. Owners report mixed experiences with quality control, with some noting alignment issues, crooked indices, and dial rotation when pushers are depressed, while others report no such issues. On balance, owners appreciate the Yema Rallygraf Meca-Quartz for its distinctive vintage styling and wearability, despite some concerns regarding quality control and the functionality of its subdial.
