Each of the four tourbillons connected to a spherical differential independently contributes to obtain a precise and reliable timing rate, especially in static positions. The spherical differential transmits the average timing rate of the four tourbillons, thus improving the chronometric performance from all the regulating organs.
Greubel Forsey was founded in 2004 by Robert Greubel and Stephen Forsey. The company first launched the Double Tourbillon 30° Vision, featuring a completely new inclined tourbillon movement. Greubel Forsey timepieces are highly technical, innovative and timeless, featuring a particularly meticulous finish being one of Greubel Forsey’s unique characteristics in redefining contemporary watchmaking.
