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.

Hamilton Jazzmaster Open Heart Auto

The Hamilton Jazzmaster Open Heart Auto is noted for its dressy yet versatile design, featuring striking gradient dials and intricately shaped cutouts that reveal the H-10 movement. It boasts an 80-hour power reserve and Nivachron hairspring. The watch is available in 36mm, 40mm, or 42mm stainless steel cases. On balance, the Hamilton Jazzmaster Open Heart Auto is appreciated for its visually engaging dial and movement display at its price point.

From video reviewers

The smoked dial's precision cutouts offer a captivating view of the automatic movement. Legibility is compromised by the open-heart design.
