Robert Greubel and Stephen Forsey have been working together for nearly two decades in a relationship founded on their shared technical creativity. In 1999, they began working on a new generation of tourbillon specifically designed to improve the timekeeping of the mechanical watch. Four years later they unveiled Greubel Forsey and stunned horological aficionados with their innovative timepieces which clearly demonstrate their twin goals of innovation and excellence.

Celebrated as the duo's '1st fundamental invention', the Double Tourbillon 30° Vision features a double tourbillon movement comprising an auspicious 128 parts and weighing an astoundingly light 1.17 grams. It is so named because of the two tourbillon carriages that are linked at a 30° angle - the exterior tourbillon measuring 15 mm in diameter revolves once every four minutes whilst the smaller interior tourbillon, inclined at 30°, revolves once a minute. Such a magnificent structure greatly compensates for the effect of gravity on the balance wheel's oscillation. Leaving no room for error, this astounding timepiece is also equipped with twin barrels equipped with a slipping spring so as to avoid excess winding tension, as well as a conical gearing with profiled teeth for optimal power transmission.
