The movement developed and manufactured for the BRX2 is square and thin, it is called the caliber BR380. With this time piece, Bell & Ross is going extreme into the simplification of watchmaking construction.
So far, Haute Horlogerie calibers have been housed In BR01 and BRX1 time pieces: Regulator tourbillon and Grand Minuteur Tourbillon in BR01, Skeleton Chronograph Tourbillon in BR-X1.
A unique minimalistic construction
To protect the movement from outside hazards, the frame is closed with two plates of sapphire, one on top, the other one on the back. These plates are milled and polished for hours and hours to achieve the perfect shape and clarity. Large beveled facets enrich the sides of both plates.
The two plates seat on translucent gaskets for compensation as well as water resistance. They are adjusted to the frame with the help of four screws.
A watchmaking movement
On the back side, three bridges with beveled angles let see the micro-rotor.257 pieces are cut with the highest precision, then hand-assembled and adjusted by talented watch makers working yearlong only on Grande Complications.
