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 Calendario

The Venezianico Arsenale Calendario is widely praised for its elegant Italian design, comfortable 40mm wearability, and intricate finishing that gives it a premium look, all offered at a value price point around $1,400. Reviewers note its clean dial execution and comfortable tapered bracelet, though some find the day and month subdials a bit cramped and the month pusher shape could be refined. The Miyota 9100 movement's accuracy is reported to range from -10/+30 seconds per day as standard, with in-house regulation to approximately ±15 seconds per day, though users have reported better real-world performance. Its 50m water resistance is noted as a limitation due to the 10 o'clock push-button. Overall, reviewers highlight the Venezianico Arsenale Calendario as a value-driven timepiece with a complete calendar complication and sophisticated styling.

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.
