The Quadruple Tourbillon Secret represents a special link between Greubel Forsey and the collector. The ultimate refinement, this timepiece evokes to the passionate enthusiast the promise of an exceptional movement in which a magical mechanical ballet plays out on a hidden stage visible only through the display back. The dial side redefines the expression of telling the time with its harmonious arrangement of multiple dials.
The Quadruple Tourbillon Secret redetermines the expression of time which plays out its many paradoxes. A play of seduction in which fantastic mechanisms are subtly revealed by indications imperturbably bearing witness to their existence; a play in which a contemporary dynamic is created by overlapping curves within curves, in which symmetry gives way to asymmetry.
The ultimate refinement, the ballet of the Tourbillons, is visible only through the synthetic sapphire crystal display back. This private micro-mechanical performance becomes a witness to the bond that unites the owner with the values of Greubel Forsey. A bond further strengthened by the precious exclusivity of the Quadruple Tourbillon Secret.
Each of the four tourbillons connected to a spherical differential contributes independently to obtain a precise and reliable timing rate especially in stable positions. The spherical differential transmits the average timing rate of the four tourbillons, thus improving the chronometric performance of all the regulating organs.
