Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.
Owners widely praise the Lucky Harvey Dragon for its exceptional build quality, particularly noting the titanium case and bracelet. Some owners find the watch to be large, and one owner reports the strap is not ideal. There is a split opinion on value, with some considering the brand slightly overpriced but offering good quality for the Chinese watch market, while others feel the price reflects the quality received. One owner humorously noted the dial makes reading the time difficult. Overall, owners rate the Lucky Harvey Dragon highly for its robust titanium construction and solid build quality.
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. Owners note it is the first 40mm PRX to omit the date window, and its packaging and watch box are described as exceptional. 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 watch retains the familiar 40mm case, Powermatic 80 movement, and integrated bracelet, retailing for CHF 795 / US$825. On balance, owners and reviewers rate the Tissot PRX UFO Robot Grendizer 50th Anniversary highly for its unique thematic execution and desirable packaging, despite some polarizing dial aesthetics.
