When Robert Greubel and Stephen Forsey first decided to develop a high performance Tourbillon regulator, they paid homage to its famous inventor, Abraham Louis Breguet, by making this decisive technical advancement. Greubel Forsey's first invention is an innovative Double Tourbillon mechanism, with one Tourbillon cage – inclined 30˚ and rotating in 60 seconds – inside another cage, rotating every four minutes, to average out gravity-induced errors on the oscillator.

In order to appreciate the mechanical ingenuity and the nobility of this new mechanism, the architecture of the movement as well as the organization of the dial allows direct and total visibility of the aerial ballet of the coupled tourbillon carriages, cradling the system of the balance wheel.

Invention

Double Tourbillon 30˚

Inside a cage which rotates in four minutes, the interior cage containing the balance and spring assembly is inclined at an angle of 30˚ relative to the first cage and completes a revolution in sixty seconds. The combination of the 30˚ inclination with the different rotational speeds of the two tourbillons improves timekeeping by averaging out positional errors due to gravity in all usual wristwatch positions and especially in stable positions.
