Official description
The Double Tourbillon 30° Edition Historique closes the Double Tourbillon 30° Contemporaine line. There have been three lines of the Double Tourbillon 30° since its debut in 2004 when it launched the Greubel Forsey adventure: Contemporaine (Vision and Secret), Invention (Invention Piece 1) and Technique (Double Tourbillon 30° Technique).
The complexity of this timepiece is visible in its intricate tourbillon system and gold dial with three sapphire crystal plates featuring the story of the Double Tourbillon 30° in structured three-dimensional text. Bevelled relief on the case side provides another distinctive feature.
The Double Tourbillon 30° Edition Historique is available in two unique series of 11 pieces in 5N red gold and 11 pieces in platinum.
