What people say

Owners + reviewers, side by side

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

Atelier Wen Ancestra Launch Edition

The Atelier Wen Ancestra Launch Edition is widely praised for its unique hand-hammered grand feu enamel dial, featuring Chinese arts and crafts and micro-etched poetry on its custom French movement. Owners and reviewers highlight the dial's dramatic gradient and the flush-set baguette diamond hour markers, all housed in a compact 38mm steel case. The movement is noted as superior to standard ETA or Sellita options. Some owners feel a seconds hand would be a welcome addition, and the $5,850 price point is considered a significant step up, with one commenter finding the brand overpriced. Overall, owners and reviewers rate the Atelier Wen Ancestra Launch Edition highly for its exceptional dial artistry and unique movement at its price.

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.
