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 ULTRA-CHRON CLASSIC

The Longines ULTRA-CHRON CLASSIC is widely praised for its high-beat 5Hz movement, offering superior accuracy and a smooth seconds hand, with reviewers noting its TIMELAB certification for chronometer standards. Owners and reviewers alike commend its faithful retro design, capturing beloved 1960s details with modern relevance and a charming appearance. The bracelet is described as comfortable and refined, featuring a micro-adjustment clasp, and the sunray silver dial with sparkling indices is a notable strength. Some owners, however, find the 11mm thickness detracts from a vintage feel, and there is a desire for a no-date version. The 40mm case wears larger than expected, with many suggesting the 37mm version offers superior wearability and fit for most wrists, and its 50m water resistance is considered not exceptional. Overall, owners and reviewers rate the Longines ULTRA-CHRON CLASSIC highly for its accurate high-frequency movement and successful retro design at its price point.

From video reviewers

The watch's high-beat movement, certified by TimeLab Geneva as an Ultra-Chronometer, is a notable feature. The relatively high price compared to its competitors is a drawback. Reviewers disagree on the optimal case size, with one reviewer mentioning 41mm and 43mm, and the other mentioning 37mm and 40mm.
