IP3 pays homage to Robert Greubel and Stephen Forsey's Third invention, the Tourbillon 24 Secondes Incline. Greubel Forsey Watches
It features a single tourbillon cage inclined at a 25 degrees that rapidly rotates in 24 seconds to guarantee maximum efficiency and optimal performance on the wrist.
A large 24-hour display dominates the dial: red indicator for hour, blue for minutes. The power reserve at 2 o'clock, is visually balanced by the tourbillon at 8 o'clock. A sub-seconds dial at 5 o'clock ensures the overall equilibrium of the timepiece.
Invention Piece 3 is available in a unique series of three limited editions, comprising three versions of 11 watches.
