Reviews

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

OLTO-8 SHOT Skeleton Automatic Watch

Owners widely praise the OLTO-8 SHOT Skeleton Automatic Watch for its striking, "crazy" yet not over-the-top style, featuring a cool black movement and a well-holed silicone strap. Reviewers note the nice polish and slim profile, with one owner appreciating the changing numbers complication and its appearance in person, though another finds the recessed numerals unappealing. Some owners report noticeable rotor noise from the automatic movement, while one experienced a movement failure within a month and cited poor customer service. On balance, owners rate the OLTO-8 SHOT Skeleton Automatic Watch positively for its unique aesthetic and slim wearability, despite isolated concerns about movement reliability and customer support.

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. Owners note it is the first 40mm PRX to omit the date window, and its packaging and watch box are described as exceptional. 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 watch retains the familiar 40mm case, Powermatic 80 movement, and integrated bracelet, retailing for CHF 795 / US$825. On balance, owners and reviewers rate the Tissot PRX UFO Robot Grendizer 50th Anniversary highly for its unique thematic execution and desirable packaging, despite some polarizing dial aesthetics.
