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 3H

The Echo/Neutra Averau Ceramic 3H is widely praised for its full lume dial and accessible ceramic and titanium construction. Owners appreciate the quality feel of the bracelet and the reliable Sellita SW200-1 movement, with one noting excellent underwater water resistance. Despite some owners finding the 51.5mm lug-to-lug measurement too large for smaller wrists, another found the 13mm thickness did not feel bulky. There is a split opinion on the double index at 12 o'clock, and one owner reports a loud rotor. On balance, owners and reviewers rate the Echo/Neutra Averau Ceramic 3H highly for its striking full lume dial and innovative material construction 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.
