What people say

Owners + reviewers, side by side

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

CWC E9 Automatic Diver Watch

Owners widely praise the CWC E9 Automatic Diver Watch for its military-spec toughness and satisfyingly easy-to-wind crown, with one owner calling it a perfect reissue due to its thin case, small size, and legibility. Some owners appreciate its durability and value as a beater or summer watch, noting its solid bars are a military requirement and highlighting its significant wrist presence and unique "Jolly Roger" dial design. Critics find the CWC E9 Automatic Diver Watch overpriced for its mineral crystal and 60-click bezel, despite its military heritage and HAQ movement, and its luminous paint is noted as low glow. Overall, owners rate the CWC E9 Automatic Diver Watch highly for its military-spec toughness and wrist presence, despite some reservations about its 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.
