Atmos-Tischuhr - Jaeger-LeCoultre - - Vernickeltes Messing, Kristall - 1940-1950

Schweizer Uhr, Jaeger LeCoultre, ATMOS 519, Serie 30761, aus dem Jahr 1942, mit 15 Steinen, überarbeitet bis heute.We are in front of one of the most extraordinary pieces of the horological world, and its magic lies in an almost philosophical premise: it does not need to be wound manually, nor a battery. It is powered by changes in temperature and atmospheric pressure in the environment.
The mechanism works thanks to a hermetic capsule filled with a special gas. When the temperature changes by just 1°C, the gas expands or contracts, activating a bellows that tension the spring, which makes the clock work. With that small variation in temperature, the Atmos clock will accumulate enough energy to work for two whole days. It will be continuously charged, up to the maximum. Theoretically, as long as the clock is in a room with temperature variations, it will work perpetually, without any manual intervention.
For collectors, passionate about watches, having an Atmos means having a living object at home that breathes with us.Please look carefully at the photos! They are part of the description.It will be properly packaged, in 2 boxes, for transport.
