The ethos behind Greubel Forsey's Invention Piece 1 is to pay homage to the timepiece that launched Robert Greubel and Stephen Forsey into galactic stardom in 2004: the Double Tourbillon 30°. While the 338-part calibre of the IP1 is based on the DT30, the displays, surfaces, architecture and aesthetics have all been profoundly modified and redeveloped. The exquisitely finished horological masterpiece is a solid validation of the underlying fundamental inventions of Greubel Forsey, with an objective to reinforce the link between mechanism and indication, as well as the relentless pursuit to improve timekeeping precision.
The highly original hour and minute display comprises of two triangular indicators, red for the hours and blue for the minutes, that enable the observer to follow the passing of time on two concentric semi-circles around the exquisitely finished tourbillon cages; the eccentric seconds and power reserve indicator appear to be in "orbit", reminiscent of a miniature solar system.
The unique nature of the IP1 is reinforced by a personalised message engraved in miniature bas-relief on the plate of the case back and will forever accompany the owner of this exceptional timepiece.
The IP1 was produced in a single edition comprising three unique editions of 11 watches each in white gold, pink gold such as the present watch and platinum, a number (1+1) chosen for its symbolic value representing the Robert Greubel and Stephen Forsey partnership.
