Bell & Ross exposes the architecture of the BR-X3 Micro-Rotor

The 2026 Bell & Ross BR-X3 Micro-Rotor makes its movement part of the watch’s visual structure. Horizontal and vertical bridges form an open grid beneath the sapphire crystal, with the hour and minute hands suspended above the mechanism. Production is limited to 99 pieces.

Its 40mm square steel case is 9mm thick, and a central structural plate connects the movement’s architecture with the case. A compact micro-rotor supplies automatic winding, while the movement offers a 48-hour power reserve. Water resistance is rated to 50 metres.

A grey calfskin strap with an alligator-style pattern completes reference BRX3M-MR-ST/SCA. Luminous hands keep the time visible against the exposed components, giving the otherwise intricate display a clear focal point.
