Greubel Forsey Invention Piece 3 is a luxury wristwatch by Greubel Forsey.

Invention Piece 3 pays homage to Greubel Forsey’s third invention with a fast-rotating 24-second tourbillon 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. Enhanced through a magnifying glass, extracts of a message from the inventors describing their creation and their philosophy is very finely engraved on four gold plates. The complete message can be viewed through the display back where it is engraved on a crescent-shaped plate.
