Greubel Forsey’s latest addition to its collection line-up: the Double Balancier à Différentiel Constant, culmulating years of research at SIHH 2016.
No tourbillon. But two inclined balanced wheels, joined together by a Differentiel
Spherique Constant to provide equal, and constant force to both.
The Greubel Forsey Double Balancier à Différentiel Constant. The dial is opened up to show the spherical differential and both inclined balance wheels.
Robert Greubel and Stephen Forsey began to research multiple regulators in 1999 as part of their EWT (Experimental Watch Technology) platform. 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. This new configuration is responsible for improved chronometric performance, while the Differentiel Spherique Constant cuts the margin of error in half.
