Description: Greubel Forsey is proud to present its 10th Fundamental Invention: the Nano Foudroyante. The mechanism's energy is managed at the nanojoule scale, significantly reducing the number of components and the overall dimensions. The result is a 37.9 mm timepiece that combines the world's first perpetual Nano Foudroyante with Greubel Forsey's first flying tourbillon and manual wind flyback. This timepiece, set in a white gold case, is limited to 22 timepieces.; What is nanomechanics? It is a realm beyond the miniaturization of components to the nanometric scale. When we talk about nanomechanics, we're talking about controlling energy on a nanojoule scale within a mechanical movement. This revolution in energy management within a caliber allows for a drastic reduction in both energy consumption and the number of components.; To demonstrate the feasibility of nanomechanics, Greubel Forsey has reinvented the foudroyante second. Its hand completes one revolution per second, dividing it into segments according to the movement's frequency. 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. This is an energy-intensive complication by nature. However, by managing energy on a nanojoule scale, Greubel Forsey has radically rethought its design and construction.; Compared to a traditional foudroyante that consumes 30 μJ (microjoules) per jump, the Nano Foudroyante operates with only 16 nJ (nanojoules) per jump, reducing energy consumption by a factor of 1,800. The mechanism's volume is therefore reduced by 90%. Here, the focus is not just on measuring fractions of a second bu
