Lot Essay
In 2010, Greubel Forsey were awarded the ‘L’Aiguille d’Or’ prize at the 10th Grand Prix d’Horlogerie de Genève with the ‘Double Tourbillon 30° Edition Historique’. This horological masterpiece was created as the final version of Greubel Forsey's celebrated first invention, the ‘Double Tourbillon 30° Contemporaine’, presented in 2004. A question which has always been asked by connoisseurs of fine watchmaking is, does a tourbillon, for all its beauty and animation, genuinely increase the accuracy of a watch? The Double Tourbillon 30° Technique successfully answered this question in 2011 when it won a further award - the ‘Concours International de Chronométrie’ with an incredible score of 915 points out of 1000, the highest in the competition to date.
Made in a limited edition of only 11 examples each in red gold and platinum, this Double Tourbillon 30° Edition Historique is even more impressive and special as the movement has two engraved gold plates featuring Robert Greubel's and Stephen Forsey's signatures. Furthermore, the numbered edition plate found on the standard production models in the front left register has been replaced to simply say 'DT 30°'.
Named the ‘Double Tourbillon 30°’ due to the angle that links the two mobile cages, the patented double tourbillon system is a decisive technical advance and milestone in watchmaking history which undertook more than four years of research and development. Inside an exterior tourbillon with a diameter of around 15 mm which turning once every four-minutes, an interior tourbillon, smaller in size and inclined at 30 degrees in relation to the first cage, revolves once every 60 seconds. To guarantee even more perfect time-keeping, this revolutionary complication permanently compensates the rate of gravity-related errors in all positions.

Robert Greubel and Stephen Forsey have been working together for over 20 years in a relationship founded on their shared technical creativity and quest for perfection. The two watchmakers are fabled for their exceptional and avant-garde horology, combining highly complicated mechanical functions with uncompromisingly provocative styling concepts.
The duo became legends in the world of modern, independent watchmaking when they began developing complicated movements for Renaud & Papi in 1992. Greubel and Forsey decided to branch out on their own in 1999, setting up as the independents, CompliTime Greubel, la Neuveville and Bureau d’Etude et Prototype, le Locle, respectively. From this moment forward, they are focused on designing a new generation of tourbillons specifically developed to improve the timekeeping of the mechanical watch.
