Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The Dryden Chrono Diver Series 1 is a 42mm mechaquartz chronograph featuring a dual-curved sapphire crystal and 100m water resistance. Owners note the VK63 movement's characteristic chronograph hand not resetting perfectly to zero, a trait present on this specific watch. The case exhibits polished chamfers on the upper lugs, and it utilizes Swiss Superluminova BGW9. On balance, owners appreciate the classic case shape and dial design of the Dryden Chrono Diver Series 1 at its price point, despite the mechaquartz movement's known reset behavior.
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.
