Robert Greubel and Stephen Forsey have been working together for nearly two decades in a relationship founded on their shared technical creativity. In 1999, they began working on a new generation of tourbillon specifically designed to improve the timekeeping of the mechanical watch. Four years later they unveiled Greubel Forsey and stunned horological aficionados with their innovative timepieces which clearly demonstrate their twin goals of innovation and excellence.
The groundbreaking Quadruple Tourbillon à Differential encapsulates the pioneering advances of the brand, boasting an impressive four separate tourbillons that are separated into two regulating organs, connected by a spherical differential which calculates median precision for the time display. Each regulating organ comprises a balance wheel oscillator placed in a cage of a first tourbillon that is inclined at 30 degrees and rotates once a minute, this mechanism is then placed within a second tourbillon that rotates every four minutes. This horological masterpiece is quipped with a 50 hour power reserve via two fast-rotating barrels that transmit their energy to the two regulating organs using the spherical differential. The construction and adjustment of these three-dimensional multi-axis whirlwinds is pure artistry in the realm of high complications.
