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 Automatik

The Sternglas Naos Automatik is praised for its stylish Bauhaus design and solid build quality for its price, featuring a sapphire crystal and elegant case. However, some dial text is too small and slim for easy readability, and the Milanese strap and clasp are considered lower quality, with the quick-change system also not meeting the brand's advertised standard. One owner found the 38mm model lighter than expected and preferred it over a Seiko SRP703 and an Apple Watch. Overall, owners and reviewers highlight the Sternglas Naos Automatik's attractive Bauhaus design and good value, despite some criticisms of dial legibility and strap quality.
