Inside a cage which rotates in four minutes, an interior cage containing the balance wheel is inclined at a 30 degree angle relative to the first cage, which rotates in sixty seconds. The combination of the 30° inclination with the different rotational speeds of the two tourbillion cages improves timekeeping by averaging out positional errors due to gravity in all usual wristwatch positions, and especially in static positions.
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.
