What people say

Owners + reviewers, side by side

Synthesized for each watch independently from owner discussions, enthusiast forums, written reviews, and video reviewers.

Hamilton Jazzmaster Auto

The Hamilton Jazzmaster Auto is widely praised for its excellent value, clean and uncomplicated design suitable for various occasions, and comfortable wearability, with a 40mm or 42mm case size that is considered unobtrusive. Reviewers highlight its refined H-21 movement, which offers a 60-hour power reserve, and distinctive sunray dials. Overall, owners and reviewers rate the Hamilton Jazzmaster Auto highly for its impressive balance of contemporary style and traditional watchmaking at its price point.

Sternglas Naos Pro Automatik

The Sternglas Naos Pro Automatik is praised for its slim 9mm case and Bauhaus dial design, featuring clear hour markers and a framed date window. Owners note the upgraded Miyota 9015 movement with a 4Hz beat rate. Accuracy is reported as -10/+30 seconds per day, which is not ideal for precision enthusiasts. The five-link bracelet's lack of fitted end-links and the optional bracelet's chunkiness are flagged as areas lacking refinement. Overall, reviewers highlight the Sternglas Naos Pro Automatik's improved wearability and premium feel at its price point.

From video reviewers

The Bauhaus design is a strength. The value proposition is a weakness.
