Tissot PRX UFO Robot Grendizer 50th AnniversaryvsYema Rallygraf Meca-Quartz II

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 II for its cool retro 70s vibe, faithful reissue of a thin vintage design, and excellent build quality for its price, with particular commendation for its tactile pushers and top-notch Milanese strap. The watch is noted for its substantial, weighty feel and well-aligned indices, and the Seiko VK64 meca-quartz movement provides a sweeping chronograph hand. However, some owners find the meca-quartz ticking not very smooth, the left subdial a "useless" 24h indicator, and the watch overpriced compared to similar models. Several owners report disappointing alignment issues with indices, and one owner experienced the dial rotating slightly when chronograph pushers are depressed or when adjusting the time, with these issues not resolved during service. On balance, owners rate the Yema Rallygraf Meca-Quartz II highly for its retro styling and perceived value, despite some recurring quality control concerns.
