What people say

Owners + reviewers, side by side

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

Bell & Ross BR 01 INSTRUMENT DE MARINE

The Bell & Ross BR 01 is recognized as a bold, 46mm "instrumentation watch" that drew inspiration from airplane cockpit altimeters upon its 2005 release. While one reviewer found a smaller variant in the line too flat and difficult to wear, the BR 01's unique design and historical significance are acknowledged. On balance, the Bell & Ross BR 01 is noted for its distinctive cockpit-inspired aesthetic and its impact on watch design at its launch.

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.
