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.

Grand Seiko SBGP009

Grand Seiko SBGP009 owners note its "normal quartz" movement, and one owner criticizes the bracelet for lacking a taper. One owner cites a 40-year-old Seiko quartz watch that has only required battery changes as evidence of the reliability of Grand Seiko's quartz movements. On balance, owners value the Grand Seiko SBGP009 for its perceived long-term reliability.
