What people say

Owners + reviewers, side by side

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

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.

Vario 1945 A-11S Solar Quartz

Owners widely praise the Vario 1945 A-11S Solar Quartz for its superb case finishing, legibility, and premium look, with its 40mm size proving comfortable for many wrists. Reviewers highlight its incredible value at $198, featuring a Miyota solar quartz movement and polished chamfers adding unexpected style. Some owners note the lume is poor and the 50-meter water resistance is limited, while others desire a big date complication not supported by the solar movement. On balance, owners and reviewers rate the Vario 1945 A-11S Solar Quartz highly for its excellent finishing and value proposition.
