What people say

Owners + reviewers, side by side

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

Echo/Neutra Averau Ceramic Chrono

The Echo/Neutra Averau Ceramic Chrono is praised for its excellent case finishing, high-quality dial with applied indices, and generous BGW9 lume, with reviewers and owners noting its well-proportioned 39mm dimensions and balanced dial. The black rubber strap is considered surprisingly nice, and the watch offers a competitive package at $1,970. However, the chronograph pushers are not screw-down despite their appearance, and the 100m water resistance should not be used with the chronograph engaged. The 51.5mm lug-to-lug distance is noted as potentially problematic for smaller wrists, and the engagement of the Sellita SW200 movement is described as unremarkable, with the Oyster-style bracelet considered only of reasonable quality. On balance, owners and reviewers rate the Echo/Neutra Averau Ceramic Chrono highly for its sharp design and quality finishing at its price point.

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.
