What people say

Owners + reviewers, side by side

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

AVI-8 Flyboy Spirit of Tuskegee Chronograph

Owners praise the AVI-8 Flyboy Spirit of Tuskegee Chronograph's aviation-inspired design and build quality, considering it superb value for its sub-$500 price. The 43mm stainless steel watch features a matte-black dial with aviation-style numerals and Swiss Super-LumiNova for legibility, powered by a Japanese Miyota automatic movement and protected by a sapphire crystal, with 5 ATM water resistance. Overall, owners rate the AVI-8 Flyboy Spirit of Tuskegee Chronograph highly for its compelling design and exceptional value 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.
