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 S434 Pro Diver

Owners widely praise the Sugess Seestern S434 Pro Diver for its impressive finishing and craftsmanship at its price point, highlighting the applied indices that play with light, excellent BGW9 lume, and attractive color options. Specific positive notes include the domed sapphire crystal, short lug-to-lug, and on-the-fly clasp adjustment. However, some owners report quality control issues such as misaligned bezels or indices, while others with V2 models experience no such problems. Caveats include slight bezel back play, light AR coating on the crystal, and a clasp that could be smoother, with one owner desiring a color-matched date wheel. On balance, owners rate the Sugess Seestern S434 Pro Diver highly for its exceptional value and build quality, particularly the dial finishing and lume.

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.
