What people say

Owners + reviewers, side by side

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

Lorier Roosevelt

Owners widely praise the Lorier Roosevelt's stunning dial, precise stamping, and clean printing, with its brass case and Horween strap also receiving positive remarks. Some owners find it wears perfectly on a 7" wrist. However, the Miyota 9-series rotor is noted as being "insanely loud," and the original $800 price point is considered steep by some, particularly given the lack of lume and competition. One owner sold it for $525, highlighting it as a great deal on a sold-out item. Overall, owners value the Lorier Roosevelt for its attractive dial and case finishing, though price and rotor noise are points of contention.

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.
