Invention Pièce 1 is a wristwatch by Greubel Forsey.

The Invention Piece 1 is a tribute to the Double Tourbillon 30°, the first fundamental “Invention” by Robert Greubel & Stephen Forsey, at which they had worked for four years. Volumes and surfaces are rearranged, the famous double tourbillon is located at the heart of a completely new indication two triangular hand elements - red for the hours, blue for the minutes - allow you to track the progressing time on the semicircle concentrically arranged in relation to the movement. A magnificent piece, a real sculpture for the wrist, in three unique series (red gold 5N, white gold and platinum). With a further surprise on the caseback is found as engraving on a gold plate the history of the “invention”.
