What people say

Owners + reviewers, side by side

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

Venezianico Arsenale Avventurina

Owners and reviewers widely praise the Venezianico Arsenale for its exceptional finishing and wearability, with a thin case profile and comfortable strap options. The Côtes de Genève dial and overall luxury appearance are frequently highlighted as significant strengths, especially considering its value proposition. One owner noted slightly misaligned hour markers, while a reviewer found the strap-changing mechanism difficult and the watch lacking lume. Accuracy figures vary, with one source reporting -10/+30 seconds per day for the Miyota 9100 movement. Overall, owners and reviewers rate the Venezianico Arsenale highly for its impressive finishing and comfortable wearability at its price point.

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.
