Alsta SuperautomaticvsTissot PRX UFO Robot Grendizer 50th Anniversary

Owners and reviewers widely praise the Alsta Superautomatic's excellent retro 70s dive watch design, with a strong connection to the movie Jaws. The contrasting case finishes and dial build quality are well-regarded, and the comfortable Tropic strap is a plus. However, the watch is considered egregiously overpriced at MSRP, with some noting a Seiko NH35 movement and stamped clasp as disappointing for the price. The bezel lacks lume, and one reviewer criticized the bracelet's poor detailing and less crisp machining. The Alsta Superautomatic is seen as a fun summer piece around $500-600, oozing 70s cool. On balance, owners and reviewers rate the Alsta Superautomatic highly for its vintage-inspired design and Jaws movie connection, despite significant price concerns at MSRP.

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.
