In 2025, Bell & Ross introduced the BR-X3 Tourbillon Micro-Rotor model. The watch featured a mechanism with a micro rotor and tourbillon, housed in a square-shaped case. The 2026 novelty reimagines this design without the tourbillon.

The original design, with intersecting straight bridges, was inspired by the abstractions of Dutch artist Piet Mondrian, as well as the modernist architecture and furniture design of Charlotte Perriand.

The watch case (a 40 x 40 mm square) is a stainless steel frame to which two blocks of sapphire glass are attached. The upper glass is secured by 4 signature Bell & Ross screws. Thanks to the micro rotor, the case thickness is only 9 mm.

The minimalist case design is continued by the lattice structure of the movement. There are no superfluous details on the dial - only 2 hands with luminescent material that glows blue in the dark. The open balance at the bottom of the dial is visually balanced by the micro rotor.

The model is powered by the BR-CAL.390 caliber, manufactured by Concepto. The visual impact of the mechanism is enhanced by the contrast between rhodium-plated components and polished-satin bridges over micro-blasted plates. The power reserve of the movement is 48 hours.

The new model is offered on a gray calf leather strap. The release is limited to a series of 99 pieces. The approximate cost of the model is CHF 20,100.
