Greubel Forsey: Invention Piece 3 Platinium/2010

To pay homage to their third invention, the Tourbillon 24 Secondes Incliné, Robert Greubel and Stephen Forsey have taken on the challenge of housing a watch mechanism, combining complex and innovative techniques within an unprecedented architectural setting.

The third invention consists of a single tourbillon cage inclined at a 25° angle and performing a rapid rotation in 24 seconds. This utterly original mechanism guarantees the watch maximum efficiency and optimal performance on the wrist.

Invention Piece 3 features a totally unconventional display with the plates themselves serving as the base for the timekeeping indicators. The four gold plates are engraved with a portion of a personal message from Robert Greubel and Stephen Forsey providing an insight into the complex process involved in creating the extraordinary mechanism of this third invention.

In a league of its own, Invention Piece 3 shows the time on a large 24-hour display taking up most of the space on the dial side. The minute display is concentric to the hour dial, with the hours distinguished by a red indicator and the minutes by a blue one. The power reserve, offset at 2 o’clock, is visually balanced by the tourbillon at 8 o’clock and provides linear reading of the indications. A sub-seconds dial at 5 o’clock ensures the overall equilibrium of the timepiece. Turning the watch over, the tourbillon, supported by a distinctive arrow-shaped bridge, provides an aesthetical link between the front and back of the watch and it can also be admired via the lateral convex sapphire crystal on the side of the case.
