Greubel Forsey’s first invention is an innovative double tourbillon mechanism (DT30), with one tourbillon – inclined at 30° and rotating in 60 seconds – inside another rotating every four minutes, to average out gravity-induced errors on the oscillator.
This approach was validated in 2011 when a Greubel Forsey Double Tourbillon Technique won the 2011 International Chronometry Competition held by the Le Locle Museum of Horology, as well as the International Chronometry Competition in the same year for the Double Tourbillon 30 Technique.
Plus the coveted Grand Prix de l’Aiguille d’Or at the Grand Prix de l’Horlogerie de Genève in 2010 for the Double Tourbillon 30° Édition Historique.
