The spherical differential linking the four tourbillon carriages of the Quadruple Tourbillon is a prime example of Greubel Forsey's inventive approach, as it exhibits an unprecedented degree of complexity, refinement and timekeeping performance.
Four asynchronous tourbillons independently contribute to its high precision. The spherical differential acts like a car's differential in distributing torque between two wheels while allowing them to rotate at different speeds.
The asymmetrical format of the two double tourbillons provides clear visibility to all carriages on the dial side, enables an additional lateral view through the side-window and eliminates the necessity for a larger movement diameter - all in a highly distinctive elegant case.
