Interesting facts:
Even though Leonardo da Vinci was able to prove that the production of a perpetual motion machine was physically impossible, it was still attempted time and again. In 1928, Neuchâtel engineer Jean Leon Reuter invented the technology for a clock whose energy source was drawn from the ambient air, from the atmosphere so to speak.
As there were repeated problems with the watches, the movements were manufactured by Le Coultre et Cie in Switzerland from 1933 and in 1935 the production rights for the Atmos watch were transferred to Ets. Ed. Jaeger in 1935.
The technical principle of the movements built by Jaeger LeCoultre from 1936 onwards is simply captivating: a mixture of a liquid and ethyl chloride gas is contained in a hermetically sealed capsule. As the temperature rises, the mixture expands, and as the temperature falls, it contracts, causing a bellows in the pressure box on the back of the watch to move like an accordion. This movement continuously winds up the movement. In the range between 15 and 30°C, a change in temperature of just one degree Celsius is enough to provide the energy for around two days of running time.
