This mechanism pushes the limits of timekeeping. Two inclined balance wheels optimise performance in stable positions, while the Differentiel Spherique Constant provides more steady amplitude. “Augmented” architecture Aesthetically, this Timepiece is both understated and yet complex. The eye-catching wide aperture with powerful three-dimensional aspects, extensively reveals the heart of the mechanism.
The first prototype to feature a fixed oscillator, the Double Balancier Incliné, was presented at Baselworld in 2009, as the sixth Greubel Forsey invention. The two inclined balance wheels – initially positioned one above the other – now occupy distinct and separate three-dimensional spaces.

Instead of a Tourbiilon the Double Balancier 35° features two inclined fixed-oscillators coupled with a spherical differential, which provides the average of their rates to the gear train and time display. The 35° inclination of the balances allows for larger diameter balance wheels (better inertia/more stable timekeeping)
