The Asym trique was the model that made it possible to incorporate the Tourbillon 24 Secondes Greubel Forsey’s third Fundamental Invention, visible at 8 o’clock into a timepiece for the first time. This then paved the way for the Contemporain and Vision versions. The latter model played an important role in the history of Greubel Forsey as it was awarded the Grand Prix de l’Aiguille d’Or in 2015. This is one of the reasons for this tribute.
Following on from the Double Tourbillon 30° Edition Historique unveiled in 2010, this is the second time that a Greubel Forsey timepiece has been honored as an Edition Historique, marking an end to a collection.
