Glycine Sea KrakenvsTissot PRX UFO Robot Grendizer 50th Anniversary

The Glycine Sea Kraken is widely praised for its retro design and excellent case finishing for its price, with reviewers noting crisp dial printing and an elegant stainless steel bezel. Owners report excellent accuracy, with some seeing deviations as low as 1 second per day, though one user observed up to a 6-second loss during high activity. The 39mm size is generally considered comfortable, though its 48mm lug-to-lug measurement may be an issue for smaller wrists. The bezel action is consistently flagged as strong with no back-play. The included leather strap is frequently criticized as unsuitable for a diver and often replaced. On balance, owners and reviewers rate the Glycine Sea Kraken highly for its vintage aesthetic and strong value proposition, particularly given its adjusted Sellita SW200 movement and limited edition status.

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.
