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.

LONGINES SPIRIT FLYBACK PROTOTYPE

Owners widely praise the Longines Spirit Flyback Prototype for its attractive finishing, COSC-certified movement, and value as a flyback chronograph. Reviewers highlight its refined 39.5mm case and simplified dial, while some owners appreciate the reduced thickness and improved wearability compared to larger variants, with a lug-to-lug distance noted as potentially long for smaller wrists. The watch features a 68-hour power reserve and a bespoke L791.4 movement. However, the case thickness is a consistent point of discussion, with multiple sources citing 17mm, though some reviewers suggest thoughtful design makes it wear closer to 13.5-14mm. Owners are split on the dial's aesthetic, with some preferring previous configurations with gold subdial rings and concentric textures over the current flat matte dial and cut-off numbers. The leather strap is also noted as stiff and pinching.
