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.

Vaer G5 Meridian GMT

The Vaer G5 Meridian GMT is a compelling and affordable true GMT watch, featuring the Miyota 9075 movement. Reviewers note its 39mm stainless steel case, which is described as chunky but visually minimized by twisted lugs, and a highly domed sapphire crystal that contributes to reflections. The glossy ceramic bezel also adds to its shiny appearance. On balance, owners and reviewers rate the Vaer G5 Meridian GMT highly for its true GMT functionality and value.
