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.

Lorier Zephyr

Owners widely praise the Lorier Zephyr for its stunning guilloche-style dial, refined and perfectly sized unique case shape, and comfortable wearability. The Miyota 9 series movement is noted by owners as being a little noisy, with a rotor whirring audible on quick hand movements. On balance, owners rate the Lorier Zephyr highly for its distinctive dial and case design at the price.

From video reviewers

The watch's vintage aesthetic and value for money are praised. The bracelet's refinement and perceived rattle are noted as a drawback.
