When Robert Greubel and Stephen Forsey first decided to develop a high performance tourbillon regulator, they set out to both pay homage to its famous inventor, Abraham Louis Breguet, and to make a decisive technical advancement.
In order to respond to the specific requirements of the tourbillon in a wristwatch, Greubel Forsey developed an innovative double tourbillon. One carriage, rotating in 60 seconds and inclined at 30°, rotates inside another, which is itself rotating every four minutes. Rotating a tourbillon inside another tourbillon in this manner averages out errors induced by the force of gravity on the balance. The construction allows for superior chronometric performance; a minimum volume/maximum balance diameter ratio; and enables the superbly finished mechanism to be appreciated visually.
The Double Tourbillon 30° is now available in two renditions: 'Vision' and 'Secret'. Vision features an open dial displaying the complication for all to view, while 'Secret' conceals its artistry behind the dial while allowing viewing discreetly through the display back.
Greubel Forsey carries out fully independent production of fine watches in its workshops in La Chaux-de-Fonds. These watches are highly technical, innovative and timeless, and feature a particularly meticulous finish that is one of Greubel Forsey’s defining characteristics.Find out more >
