To celebrate their 20th anniversary, Greubel Forsey presents its 10th Fundamental Invention: the Nano Foudroyante EWT. The mechanism’s energy is managed at the nanojoule scale, significantly reducing the number of components and the overall dimensions. The result is a 37.9mm timepiece that combines the world’s first perpetual Nano Foudroyante with Greubel Forsey’s first flying tourbillon and manual wind flyback. In this Nano Foudroyante, each oscillation of the 3 Hz balance wheel produces two beats, totaling six beats per second, allowing the hand to divide the second into six distinct segments. The focus is not just on measuring fractions of a second but as a proof of concept for a completely new approach to watchmaking as it eliminates the entire gear train required in a traditional foudroyante. Set in a white gold and tantalum case, this revolutionary timepiece will be limited to just 11 pieces.
