The Quadruple Tourbillon is a wristwatch by Greubel Forsey.
Between art and technological innovation, the second pioneering invention by Robert Greubel and Stephen Forsey is situated. It brings both even closer to the absolute summit of watchmaking. The four tourbillons of this stunning composition contribute independently to the unique accuracy of the watch. This is made possible by the asynchronous positioning of each of these tourbillons in combination with two autonomous control elements. These are housed each in its own tourbillon cage and connected via a spherical differential with the train wheels of the watch and in this way connected with the time indication. Hence highest virtuosity, and certainly a new chapter of the watchmaking art.
