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.

Zelos Eagle 2

Owners widely praise the Zelos Eagle 2's unique meteorite dial and titanium case, with one owner describing it as a "work of art" featuring a fully lumed dial and a scratch-resistant 1,200 Vickers hardness-coated case. The LaJoux Perret G100Soigne movement provides a 68-hour power reserve. Some owners, however, find the dial layout "ugly" and the font thick, while others note minor QC issues like misaligned markers. On balance, owners rate the Zelos Eagle 2 highly for its distinctive meteorite dial and titanium construction at its price point.

From video reviewers

The watch's compact size is a notable strength, with a 39mm diameter case and 11mm thickness making it suitable for a pilot's watch. A potential weakness is the lug-to-lug fit, which may be too large for smaller wrists. Reviewers disagree on the bezel, with one reviewer highlighting the Cerakote finish as a standout feature, while another mentions the watch's bezel in passing without comment.
