Condition:
Very good condition. Absolute accuracy. Comes with original set-up and instruction booklet.
There are minimal signs of use due to age. The photos are not "embellished", the case condition is as shown in the photos. In most of the photos the clock is shown without the front glass, due to the reflection of the flash when the photo was taken.

Points of interest:
Even though Leonardo da Vinci was already able to prove that the production of a perpetual motion machine is physically impossible, it was nevertheless attempted again and again. One such attempt was made by Jean Leon Reuter, an engineer from Neuchâtel, who in 1928 invented the technology for a clock whose energy source was drawn from the surrounding air, from the atmosphere, so to speak.
Since there were always problems with the clocks, the movements were manufactured by the company Le Coultre et Cie in Switzerland from 1933 onwards, and in 1935 the production rights for the Atmos clock were transferred to Ets. Ed. Jaeger.
The technical principle of the movements then built by Jaeger LeCoultre from 1936 onwards is simply captivating: a mixture of a liquid and the gas ethyl chloride 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 located on the back of the watch to move like an accordion. This movement continuously winds the movement. In the range between 15 and 30°C, a change in temperature of just one degree Celsius is enough to supply the energy for about two days of operation.
