Greubel Forsey Quadruple Tourbillon a Differentiel

With new Quadruple Tourbillon "A Differentiel", Robert Greubel and Stephen Forsey have once again demonstrated their inventive and creative prowess. They have engineered the four Tourbillons together in a contemporary design, in which elegance and harmony are the dominant features, which are connected at the heart of two autonomous regulating organs. Each of the two regulating organs is composed of a balance wheel oscillator placed in a cage of a first Tourbillon rotating once a minute and inclined at 30 degrees. This mechanism rotates within the cage of a second Tourbillon rotating every four minutes. The two oscillators, independently regulated inside the four Tourbillons, are coupled by a spherical differential which transmits their combined precision to the time display. Two barrels connected in series supply power through the spherical differential to the Tourbillons. Wearing a Quadruple Tourbillon "A Differentiel" is to enter the universe of Robert Greubel and Stephen Forsey, and to share, appreciate and be empathetic to the essential values emanating from their Invention.

The workings of a tourbillon are mind boggling to me! A work of genius in my opinion...but then so are egg rolls! LMAO! I'd love to see that watch in person. Amazing! Thanks Vito.
