Invention Piece

To pay homage to their Fundamental Inventions, Greubel Forsey reinterprets its original timepieces by creating Invention Pieces.

Invention Piece 1

The Invention Piece 1 embodies Robert Greubel and Stephen Forsey’s wish to honour the Double Tourbillon 30° and to raise the bar yet another notch by opening up whole new vistas for their first major invention.

Invention Piece 2

The Quadruple Tourbillon is honored, with Invention Piece 2, focusing on its innovative mechanism through a completely new technical architecture. The movement assures full visibility through the sapphire crystal, convex sapphire display back and lateral window. Two Double Tourbillons are presented head-to-tail, allowing the mechanisms to be appreciated from all angles.

Invention Piece 3

Invention Piece 3 pays homage to Greubel Forsey’s third invention with a fast-rotating Tourbillon 24 Secondes inclined at 25°. The time display features a large 24-hour dial outside concentric minutes and a small seconds dial at 5 o’clock. An off-centred power reserve indicator at 2 o’clock visually balances the tourbillon at 8 o’clock, which is also visible through the lateral window.
