Jean-Léon REUTTER (1899-1971), engineer from Neuchâtel, trained at the Federal Polytechnic School of Zurich, then at the Higher School of Electricity in Paris, he was deeply attached to the research of perpetual motion. He focused his studies on the use of variations in temperature and atmospheric pressure. For this it uses a capsule sensitive to these variations, until obtaining an almost "perpetual" mechanism of very great energy sobriety. He filed the first patent in 1929, supported by the Compagnie Général de Radiologie de Paris. The meeting of Jean-Léon Reutter and Jacques-David LeCoultre, who bought the patent in 1935, allowed the invention to become a true emblem of the symbiosis between scientific research and watchmaking.
