The History of ... Greubel Forsey... is a watchmaking company specializing in ultra high-end timepieces. It was launched in 2004 by Robert Greubel and Stephen Forsey and is based in La Chaux-de-Fonds, Switzerland. Greubel Forsey specialize in inventing timepieces with multiple tourbillons and inclined balance wheels with the aim of improving timekeeping precision. Their approach was validated in 2011 when a Greubel Forsey Double Tourbillon Technique won the 2011 International Chronometry Competition held by the Le Locle Museum of Horology. In 2004 at BaselWorld with the introduction of their Double Tourbillon 30° (DT30). Both men had been working together since 1992 at Renaud & Papi, where they developed complicated watch movements. The Richemont

The company has invented and presented a number of tourbillon-based watches including: the Double Tourbillon 30° (DT30°), the Quadruple Tourbillon à Différentiel, the Tourbillon 24 Secondes Incliné and the GMT.

Personal Note—LNIB+LTD, Collector owned, Comes with Box set & Papers, as seen in photos... Greubel Forsey Quadruple Tourbillon GF03 OR5 CN crafted polished finish 18k Red Gold Asymmetrical shaped, lateral window with shaped sapphire crystal 3 dimensional case… The Quadruple Tourbillon à Différentiel is a blend of art and technical innovation which encapsulates the very soul of its the two creators. Transparent sapphire bridges were specifically chosen to allow unimpaired visual access to the perfectly choreographed aerial ballet of the four Tourbillons. They’ve engineered the four Tourbillons together in a contemporary design, in which elegance and harmony , the movement, an asymmetrically-shaped case was chosen. Form follows function: This allows for an extreme dial design. “The asymmetrical form is an aesthetic tribute to the synchronicity of the four Tourbillons. To complement homogeneous ensemble, the displays of the small second and the power reserve dials are semi-circular. With its sophisticated coalescence of technical Invention and artistic design, the Quadruple Tourbillon à Différentiel encapsulates the best in fine watchmaking. Wearing a Quadruple Tourbillon à Différentiel 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 culmination of five years of research and development has produced a mechanism of Four separate Tourbillons that are connected at the heart t 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”...

...“At the heart of the Quadruple Tourbillon à Différentiel, each of the four Tourbillons make their own distinct contribution towards achieving an exceptional level of accuracy. This is due to the asynchronicity of the Tourbillons’ locations relative to each other. This ensures that it is practically impossible for the balance wheels to be in an unfavorable position, no matter which angle the watch is in. By transmitting the averaged results of two oscillators, the spherical differential doubles the chronometric performance of the two regulating organs, and also minimizes the smallest variations in the performance of the oscillators. Ample energy is assured by two large, fast rotating barrels which guarantee a power reserve of 50 hours of”...
