Invention Piece 1

33 pieces (2008-2009) | White gold | Red gold | Platinum

The Invention Piece 1 embodies Greubel Forsey’s wish to honor the Double Tourbillon 30˚ and to raise the bar yet another notch by opening up whole new vistas for their first major invention. Both the architecture of the movement and the display of information symbolize the four years of meticulous research that the Inventor Watchmakers have devoted to developing the new mechanism.

In this Invention Piece 1, the volumes and surfaces of the timepiece have been rearranged according to a new technical and aesthetic structure. The latter places the Double Tourbillon 30˚ at the center of a semi-circular hour and minute display, thereby visually reinforcing the link between the mechanism responsible for measuring the time and its “symbolic” indication.

Around the tourbillon with its indicators, the absence of a dial reveals the bridges that are clearly visible on three distinct levels. This opening provides a view of the concentric gearing serving to drive the hour and minute indicators. The off-centered small seconds and power-reserve displays are reminiscent of a miniature solar system.

While the case with its signature Greubel Forsey lugs is immediately recognizable, this Invention Piece 1 expresses its unique nature, reinforced by an unexpected detail: directly engraved on a plate appearing on the case-back, a unique message from the Inventor Watchmakers will forever accompany the owner of this exceptional timepiece.

Invention

Double Tourbillon 30˚

Inside a cage which rotates in four minutes, the interior cage containing the balance and spring assembly is inclined at an angle of 30˚ relative to the first cage and completes a revolution in sixty seconds. The combination of the 30˚ inclination with the different rotational speeds of the two tourbillons improves timekeeping by averaging out positional errors due to gravity in all usual wristwatch positions and especially in stable positions.
