What people say

Owners + reviewers, side by side

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

Oak & Oscar The Olmsted Matte

Oak & Oscar The Olmsted Matte is praised for its stealthy, modern field watch aesthetic, featuring a durable ceramic-coated steel case and a clean, no-date dial. Reviewers highlight its comfortable 38mm dimensions and 100m water resistance. The watch offers exceptional value at $1,475, including two straps and a travel wallet, with a modified ETA 2892-A2 movement. One reviewer notes the ceramic coating may develop patina with heavy wear. Overall, reviewers rate Oak & Oscar The Olmsted Matte highly for its stealthy design and value proposition.

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.
