What people say

Owners + reviewers, side by side

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

Sugess Seestern Vintage S407 600T

Owners widely praise the Sugess Seestern Vintage S407 600T for its exceptional finishing, bracelet quality, and overall value at its price point. Reviewers and owners alike highlight the watch's fantastic looks and build quality, with one owner noting Seestern did a better job than the original inspiration. Some owners report a slight bezel back play and a clunky clasp, while others have no clasp complaints. Accuracy figures vary, with one owner seeing the watch run 2 seconds slow over 30 hours, and another noting a dial leaning slightly left. The watch measures 40mm wide, 14mm thick, and 48mm lug-to-lug, weighing 86g for the head and 163.4g total with the bracelet, leading some to find it heavy for wrists smaller than 7 inches. One owner questioned if the crown felt wobbly when winding or setting. On balance, owners rate the Sugess Seestern Vintage S407 600T highly for its outstanding build quality and aesthetic appeal relative to its cost.

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.
