Owners + reviewers, side by side
Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Mr Jones Watches A perfectly useless afternoon is widely praised for its creative, fun, and original design, with reviewers and owners alike highlighting its vibrant colors and ability to serve as a conversation starter. The watch is considered well-made for its price, featuring a unique aesthetic where a figure's leg indicates the hour and a rubber duck shows the minutes. Some owners report the blue nylon strap can be small in diameter. One reviewer noted the Milanese bracelet was too shiny and opted to brush it and the lugs for a more subdued look. The mechanical variant uses an STP1-11 automatic movement with a 44-hour power reserve and acceptable accuracy, while the quartz variant features a unique dial design with hour markers integrated into the watery visual. Overall, owners and reviewers rate Mr Jones Watches A perfectly useless afternoon highly for its imaginative design and good value.
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.
