What people say

Owners + reviewers, side by side

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

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.

Longines CONQUEST

Owners widely praise the Longines CONQUEST for its versatile, aesthetically pleasing design, comfortable wearability, and excellent value, with many highlighting its high-quality finishing and smooth winding action. Reviewers and owners alike note the watch's well-wearing size and blend of vintage and modern design elements. Some owners report the polished surfaces can be prone to scratches, and multiple sources flag the bracelet's lack of micro-adjustment as a significant drawback impacting fit. Lume quality is also a recurring point of criticism, with one reviewer noting only the black dial version appears to have lumed hands. Overall, owners and reviewers consider the Longines CONQUEST a highly versatile and well-built everyday sports watch offering significant value.

From video reviewers

The elegant gold dial is a notable aspect of the Longines CONQUEST. The quartz movement may be a drawback for collectors who prefer mechanical movements. Reviewers disagree on the standout feature, with one highlighting the gold dial and the other the Blue Sunburst dial.
