Jaeger LeCoultre - Atmos Elysee 1970s

Dimensions: H x W x D: 21 x 18 x 11 cm

Description:
Atmos Elysee by Jaeger LeCoultre in gold plated brass case with tortoise shell finish.
Gold plated dial with black Roman numerals.
This watch is one of the "fancy models" of the caliber 526 and was listed by Jaeger LeCoultre under the number 5820. The model was manufactured from 1970 to 1983. The specimen offered here dates back to 1971.

Fun Facts:
In 1927, the young engineer Jean-Léon Reutter presented the prototype of the Atmos watch he had developed.
The response in the press was great and so he signed a contract with the Compagnie générale de radiologie, which built and distributed the "Atmos I" under Reutter's direction from 1930 on.
Since there were always problems with the watches, the movements were manufactured by Le Coultre et Cie in Switzerland from 1933 and in 1935 the production rights of the Atmos watch were transferred to Ets. Ed. Jaeger.
They focused on developing a simpler and more robust engine and from 1938 the era of the Atmos by Jaeger-LeCoultre began.

The "watch that lives on air" uses the "breathing movements" of a gas-filled bellows created by temperature fluctuations to wind the movement.
The movement of the watch is conspicuous by its cylindrical box on the back. Inside it, a bellows-shaped expansion chamber contains chloroethyl, a gas that expands particularly strongly between 10 °C and 27 °C. The movement is then wound up.
A temperature difference of just one degree Celsius winds the watch for 48 hours. This interesting winding mechanism is complemented by an excellent movement of extreme precision with a heavy torsion pendulum.
The condition for the accuracy of the clock is a stable and vibration-free installation.

It is also worth mentioning the absolute environmental friendliness of the clock, which does not need a battery or any other electric drive, despite the unlimited running time.
For decades, the Atmos has been the official state gift of Switzerland to prominent visitors, e.g. politicians from abroad.
