What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Glycine Airman SST GMT

Owners praise the Glycine Airman SST GMT for its comfortable wear, good build quality, accuracy, lume, and historical significance. The 24-hour dial and compressor-style GMT ring are noted as great features. One owner found the Sellita SW330 movement authentic, though expected Glycine branding on the rotor. The dial is considered busy, and one owner experienced the watch stopping after a day on a winder with a rattling rotor, suggesting service. On balance, owners rate the Glycine Airman SST GMT highly for its comfortable wear and historical significance.

Tissot PRX UFO Robot Grendizer 50th Anniversary

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.
