What people say

Owners + reviewers, side by side

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

Bell & Ross BR-03 Chrono Blacktrack

Owners widely appreciate the Bell & Ross BR-03 Chrono Blacktrack for its unique square, military-inspired, stealthy all-black ceramic design and dial styled like a motorcycle's cooling grid, finding it a refreshing alternative to common styles. Reviewers note the watch's surprising wearability, particularly with flared straps, and its futuristic design with personality. Accuracy figures vary, with one source reporting +10 seconds per day for the ETA 2894-2 based BR-CAL.301 movement, which has a 42-hour power reserve. Some owners criticize the use of rebranded base movements and significant depreciation, while one reviewer found the padded, quilted strap less comfortable than usual and noted poor lume. On balance, owners and reviewers rate the Bell & Ross BR-03 Chrono Blacktrack well for its distinctive, personality-filled design.

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.
