Greubel Forsey Invention Piece 2

Greubel Forsey IP2

Greubel Forsey indulges in variations on their unique horological themes. These variations are the Invention Pieces. In 2007, IP1 celebrated the Double Tourbillon 30°, and in 2009 IP3 paid homage to the Tourbillon 24 Secondes. This year tribute is paid to the Quadruple Tourbillon in the form of the IP2, recasting the original’s innovative mechanism in a completely new movement.

The IP2 movement is comprised of 594 components housed in a 43.5 mm diameter asymmetrical case. Two double tourbillons are presented head-to-tail, allowing the mechanisms to be appreciated from all angles through front and back sapphire crystals and a lateral window. The two double tourbillon systems are coupled via a spherical differential in the center of the timepiece. Hours and minutes are indicated by a red triangle and a rotating disk on a sub-dial at 5 o’clock, which conceals the triple coaxial mainspring barrels. Small seconds are visible at 10 o’clock and the 56-hour power reserve is displayed at 11 o’clock.

IP2 is offered in a unique edition of 11 pieces in platinum, priced at SFr.750,000, and 11 pieces in 5N red gold priced at SFr.730,000.
