What people say

Owners + reviewers, side by side

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

Grand Seiko SLGB003

Grand Seiko SLGB003 owners widely praise its lightness and comfort, with a dial that offers a shifting character in different lighting conditions. Reviewers note its compact case size enhances wearability and versatility across wrist sizes. However, one owner found the dial underwhelming, and another reported a date disc issue with lower numbers not changing correctly. Some question the value proposition at around $10,000, citing the bracelet and dial as potential drawbacks, while others highlight the movement and smaller dimensions as significant positives. On balance, owners rate the Grand Seiko SLGB003 highly for its movement and compact dimensions, despite some reservations about the dial and bracelet.

From video reviewers

The watch's exceptional accuracy is a notable strength, with both reviewers highlighting its precise timekeeping. A weakness is the relatively high price point compared to other Grand Seiko models. Reviewers disagree on the ideal case size, with one reviewer noting it's relatively small at 37mm, while the other doesn't mention case size as a concern.

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.
