Invention Piece 2
To do full justice to the fundamental inventions validated through the Experimental Watch Technology platform, Greubel Forsey has developed creative interpretations that are supplementary to the original timepieces: these are the Invention Piece (IP). In 2007 IP1 celebrated the Double Tourbillon 30° and in 2009 IP3 paid homage to the Tourbillon 24 Secondes. Now the Quadruple Tourbillon is similarly honoured, with IP2 focusing on its innovative mechanism through a completely new technical architecture. IP2 is offered in a unique edition of 11 pieces in platinum and 11 pieces in 5N red gold.
