The ethos behind Invention Piece 1 is to pay homage to the Invention that launched Greubel Forsey: the Double Tourbillion 30°. The time indications, surfaces, architecture and aesthetics of Invention Piece 1 have all been profoundly modified and re-developed around the original DT30° to create this exceptional timepiece.
Reminiscent of orbiting astronomical indicators, the displays reinforce the link between the mechanism and the indication. Two triangular indicators - red hours, blue minutes - show the time, while a sub-second dial (top left) and a power reserve indicator complete the dial.
Invention Piece 1 was available in a unique series of three limited editions, comprising three versions of 11 watches and is sold out.
