Greubel Forsey presents its 8th Fundamental Invention and a new approach to the tourbillon.

The new Greubel Forsey Tourbillon Cardan, with its ultra-high rotation rate, 30° inclined plane and two constantly inclined mounting rings, promises optimum chronometric precision.

This new approach to the tourbillon combines three fundamental technologies: a high-speed tourbillon, a 30-degree inclination and a pair of inclined mounting rings. Instead of rotating once per minute, the tourbillon now completes a full rotation in just 16 seconds. On the other hand, it is inclined by 30 degrees, which optimizes it for the specific positions of a wristwatch. Finally, the pair of mobile mounting rings, connected by two 90-degree axes that tilt back and forth every 48 seconds, ensures a better relationship between angular velocity and chronometric performance.
