What people say

Owners + reviewers, side by side

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

Maen Grand Tonneau Jump Hour

Owners widely praise the Maen Grand Tonneau Jump Hour for its unique style and accessible price point for a jump hour complication, with one owner finding the red dial variant looks and wears great. However, some find the hour and minute windows, particularly the minute window, too small and the font illegible, impacting legibility. Criticism also centers on the use of a Chinese Seagull movement in a watch priced over $1,000, leading some to label it a "fashion watch" and a "scam," while others note it is selling for significantly over its original price and is not worth it. On balance, owners are split on the Maen Grand Tonneau Jump Hour, with its unique design and value proposition countered by concerns over legibility and movement choice at its price point.

From video reviewers

The watch is praised for its ultra-thin profile and classic design. Reviewers noted the unique jumping hour complication.

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.
