Four tourbillons orbiting the Earth Robert Greubel and Stephen Forsey have shown creative daring and boldness in uniting their second. Fundamental Invention, the Quadruple Tourbillon, with their ground breaking interpretation of the GMT with its outsized rotating globe. Displaying three time zones along with a universal time function, this exceptional timepiece is distinguished by its three-dimensional architecture created with extreme attention to fine craftsmanship. A Unique edition of 66 pieces in total, the first 11 of which are in white gold.
A highly complex mechanism
Working on the principle that the more different positions the regulating organ moves through, the more precise the timekeeping will be, Robert Greubel and Stephen Forsey invented the Quadruple Tourbillon with a spherical differential. Right from the original idea the concept was clear. While coupling four separate tourbillons would have been challenging, they sought a more compact solution. To save space in all three dimensions, they chose to construct the tourbillons in pairs within a unique system of compact cages, an extremely challenging feat.
Greubel Forsey GMT Sport
Strong and truly original case geometry The completely new and original titanium case, firmly positions this new GMT in a “sports” league of its own. In their creation of this timepiece, Robert Greubel and Stephen Forsey have pushed back the limits of ergonomics and wrist comfort. They have invented a totally new case form, perfectly round from above, while revealing the accentuated arched and ovoid shape from other angles.
