Greubel Forsey Quadruple Tourbillon
The spherical differential connecting the four rotating 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.
The four asynchronous tourbillons independently contribute to its extremely high accuracy.
