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.

The Double Tourbillon 30° Vision focuses on the visibility of the innovative invention, while the Double Tourbillon 30° Secret has a closed dial merely hinting at the splendid treasure beneath.
