What people say

Owners + reviewers, side by side

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

Seestern Sub 300 V4

Owners widely praise the Seestern Sub 300 V4 for its terrific fit and finish and surprising little touches at its $179 price, noting top-notch case, dial, bezel, and crystal. The bracelet is considered nice enough for the price point, and the watch is powered by the solid and reliable Seiko NH35 movement. Some owners report that the polished sides of the case show signs of wear. Overall, owners rate the Seestern Sub 300 V4 highly for its excellent case, dial, and bezel finishing at the price.

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.
