Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
The Praesidus C-47 D-day - Aluminum Patina is praised for its 38mm diameter and its dial, crafted from actual C-47 airplane doors, offering a unique patina and historical context. Reviewers note its utilitarian, vintage military aesthetic, enhanced by a sandblasted stainless steel case and acrylic crystal. The watch is equipped with a Miyota 9039 movement, 100m water resistance, and Super-LumiNova for visibility. Accuracy is rated at -10/+30 seconds per day, with a 42-hour power reserve. On balance, reviewers highlight the Praesidus C-47 D-day - Aluminum Patina's historical dial as its most compelling feature, transforming a potentially divisive material into a unique selling point.
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.
