What people say

Owners + reviewers, side by side

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

Christopher Ward Twelve X (Ti) Titanium

Owners and reviewers widely praise the Christopher Ward Twelve X (Ti) Titanium for its exceptional value, lightweight titanium construction, and comfortable wearability, with case thickness noted as under 9mm by some and around 12.3mm by others. The watch features a COSC-certified movement, either a Sellita SW300-1 or a skeletonized SH21 with a 5-day or 120-hour power reserve, and reviewers highlight excellent lume performance and improved legibility on skeletonized dials. Some find the bracelet's one-step micro-adjustment clasp convenient, while others report sharp bracelet links and unfinished clasp interiors, and one owner noted the "Arctic White" dial appeared silver. There is a split on Christopher Ward design originality and the potential for case and bracelet chamfers to be prone to dings.

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.
