DESCRIPTION

  • Invention Piece 1

    Honouring the first invention

    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. Both the architecture of the movement and the display of information symbolise the four years of meticulous research that the inventor-watchmakers have devoted to developing the new mechanism.

    In the Invention Piece 1, the creative Greubel Forsey twosome have rearranged the volumes and surfaces of the timepiece according to a new technical and aesthetic structure. The Double Tourbillon 30° is placed at the centre 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.

    The invention at the stage centre

    In contrast to the Double Tourbillon 30°, the movement driving the Invention Piece 1 has been profoundly modified and as a consequence the double cage, shifted slightly to the left and distinctly higher. This freed up space to place the object of the invention at the very centre of the highly original hour and minute display. Two triangular indicators – a red one for the hours and a blue one for the minutes – enable the observer to follow the passing of time on the mechanism’s two concentric semi-circles.

    To facilitate read-off, the 12-hour and 0-minute markers are aligned at the traditional 12 o’clock position.

    Four different rotations

    Magnificently evoking the mechanical genius of the Invention Piece 1, the various speeds of rotation of these different elements give an idea of the complexity of the mechanism: whereas the outer cage takes four minutes to perform a complete rotation and the inner cage just 60 seconds, the double hands turn in 24 hours for the hours display and two hours for minutes.

    Around the Tourbillon and its indicators, the absence of a dial reveals the frosted nickel silver bridges coated with either red gold or palladium nickel and 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-centred small seconds and power-reserve displays are reminiscent of a miniature solar system.

    Message from the Inventors

    While the case, with its signature Greubel Forsey lugs, is immediately recognisable, the Invention Piece 1 expresses its unique nature, and it is reinforced by an unexpected detail: engraved on a plate on the case back is a personalised message from the inventor-watchmakers that will forever accompany the owner of this exceptional timepiece.

    A total of 388 parts contribute to the smooth running of the movement driving the Invention Piece 1, including 128 for the double cage that weighs just 1.17 grams.

    The Invention Piece 1 is produced in a single edition comprising three versions of 11 watches each, a number (1+1) chosen for its symbolic value representing the Robert Greubel and Stephen Forsey partnership.
