After 2 years of studies and tests, BRM introduces the Birotor. The watch, with its innovating mechanism, is made with wind up rotors set with a differential, and introduces a new concept in the watchmaking industry.
The movement, suspended by 4 carbonfiber triangles (carbon or fiberglass) is fixed inside the box with an elastic (Isolastic™) system . It consists of Arcap® plates and bridges. This is a real Formula 1 watch. All the movement’s screws were replaced by bolts. Crown transfer at 2 o’clock, with its bipolar system, is a novelty. The ergonomic lugs are fixed on the case with 3 adjustable positions.
These innovations make this watch a unique piece in the watchmaking industry, one of the only pieces of the 21st century.
