The model R50 T is the latest, most innovative design emerging from BRM’s patented Isolastic System technology. The movement, shaped like an engine with its cylinder on the left, is maintained by three triangles in carbon fiber or fiberglass. On each of these triangles, a spring allows for the absorbtion of any vibration inside the case.
The calibre has a forty-eight hour power reserve and the rotor, made of Fortale HR and aluminium AU4G, has a tantalum weight.
It is presented in a 50mm case made of titanium extra hard grade 2.
