For over ten years, Greubel Forsey’s EWT (Experimental Watch Technology) Laboratory has been working to push the boundaries of mechanical watchmaking and has had particular success in the domain of the Mechanical Nano project. Thanks to this totally new concept and following the recent application of patent No. EP 3220207 A1, Greubel Forsey is unveiling the first Nano Foudroyante EWT. Compared to a traditional foudroyant jumping seconds mechanism, the Greubel Forsey Nano Foudroyante EWT consumes 1,800 times less energy and occupies 96% less space. All of this research has made it possible to create a truly original and innovative foudroyant jumping seconds mechanism that makes best use of energy and available space in the movement of a mechanical timepiece.
