Invention Piece 2Greub el Forsey

SIHH 2011 News Greubel Forsey Invention Piece 2

In ten years, no less than six significant inventions have sprung from Greubel Forsey’s EWT think tank, three of which (to date) have been celebrated by Invention Piece (IP). In 2007, IP1 paid homage to the Double Tourbillon 30°; in 2009, IP3 honoured the Tourbillon 24 Secondes. And today IP2 pays tribute to the Quadruple Tourbillon with a completely new architecture in which the focus is on its exclusive mechanism.

The two double tourbillons systems are presented head to tail and coupled by a spherical differential. A sub-dial at 5 o’clock conceals triple mainspring barrels and features a red triangle indicating hours and a rotating disk indicates minutes. Small seconds dial at 10 o’clock and 56-hour power reserve indicator at 11 o’clock complete the dial.

A unique edition of 11 pieces in platinum and 11 in red gold.
