What people say

Owners + reviewers, side by side

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

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.

Yema Wristmaster Slim Small Seconds CMM.29

Owners widely praise the Yema Wristmaster Slim Small Seconds CMM.29 for its slim 9.5mm case, unique nature-inspired dial, and brushed steel finish. The micro-rotor movement is noted for its 4Hz beat rate and 42-hour power reserve, regulated to -/+ 10 seconds per day. Some owners report concerns regarding the movement and warranty process, while a reviewer questioned the value proposition at its price point and noted minor finishing inconsistencies on a prototype. On balance, the Yema Wristmaster Slim Small Seconds CMM.29 is highly regarded by owners for its distinctive design and comfortable wearability.
