What people say

Owners + reviewers, side by side

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

Horage Decaflux

The Horage Decaflux is praised for its innovative in-house K3 movement, featuring a silicon escapement and a 96-hour power reserve, along with chronometer certification and a slim 9.98mm profile. Reviewers note its tinted sapphire crystal, lightning bolt seconds hand, and bracelet with an integrated vibe and thin clasp. The watch is priced at CHF 2,750, with preorder pricing at CHF 2,500, representing a strong value for an in-house Swiss movement. Some reviewers find the lightning bolt seconds hand slightly too wide and note a direct design homage to the Rolex Milgauss. On balance, reviewers rate the Horage Decaflux highly for its technical innovation and value proposition at its price point.

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.
