What people say

Owners + reviewers, side by side

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

Orient 75th Anniversary RA-AC0Q12L30B

The Orient 75th Anniversary RA-AC0Q12L30B is widely praised for its classy, dressy aesthetic, beautiful periwinkle or light blue sunray dial with deep-relief radial grooves, and crisp engraved bezel numerals, all within a compact 39.9mm to 40mm case. Owners consider it a great value, with some noting it looks better in person and is destined to become a classic, punching above its price point. One owner finds the dial color too feminine for a dive watch and considered the dial craftsmanship inferior to the Presage Cocktail series, while another flags the lack of lume as a drawback. The bracelet clasp and end links are consistently considered a weak point, and the steel case is noted as less rounded than other Orient divers. The watch features 200m water resistance and a 46.5mm lug-to-lug measurement. Overall, owners rate the Orient 75th Anniversary RA-AC0Q12L30B highly for its stunning dial and compact size at the price.

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.
