The Différentiel d’Égalité
Robert Greubel and Stephen Forsey first unveiled their invention at Baselworld 2008 as part of the EWT Laboratory and then presented a more advanced version of a technical demonstrator at SIHH 2010. Since then, further exciting paths have been explored to help optimise accuracy in this new timepiece. The Différentiel d’Égalité enables steady distribution of power from the mainspring barrel to the regulating organ, which maintains a constant balance amplitude during the 60 hours of the power reserve.
Balancier USA Edition 11 pieces
The “Balancier” perfectly embodies our fundamental principles. Every detail of the “Balancier” carries the unmistakable stamp of a true Greubel Forsey timepiece – the watchmaking Maison’s values are manifest in the refinement and purity of its lines and dial, the inventive architecture of its balance wheel, the sharp profile of its hands, and the engraving on the reverse of the timepiece.
