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.

Yema Superman Titanium Tourbillon CMM.31 Limited Edition

The Yema Superman Titanium Tourbillon CMM.31 Limited Edition is noted for its in-house titanium tourbillon movement offering a 105-hour power reserve and 200m water resistance, alongside a unique asphalt-grained dial. Owners find the 43mm size wearable, with one describing it as a contradictory "toolwatch" with exceptional movement craftsmanship. A reviewer flags the bracelet clasp's extension system as crude. On balance, owners and reviewers highlight the impressive movement and dial as key strengths of the Yema Superman Titanium Tourbillon CMM.31 Limited Edition.
