Jaeger LeCoultre, Atmos Vendome with original papers

Dimensions: H x W x D: 24 x 21 x 16 cm

Description:
Atmos Vendome calibre 526. model number 5857 with marble base and fluted columns.
White dial with Roman numerals. Breguet hands.
Serial number: 181925
Year of manufacture: 1964.

Both the dial and the generally architectural design of this clock are reminiscent of classicism. That is why it became famous under the names "Style", "Empire" or "Directoire". The partial greenish varnish is said to be reminiscent of oxidising bronze.

The Atmos Vendome was produced in different variations. With a gilded base or also with a marble base. The first Vendome appeared in 1962 and the model offered here from the 5857 series was built from 1962-1978.

Condition:
Freshly overhauled. Perfect functionality. Absolute accuracy.
The photos are not "embellished", the case condition is as shown in the photos. In most of the photos the watch is shown without the front glass, due to the reflection of the flash when taking photos.

I offer a one year warranty on the functionality of the movement when properly set up and handled.

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 marketed the "Atmos I" under Reutter's direction from 1930.
Since there were always problems with the watches, the movements were manufactured by Le Coultre et Cie inSwitzerland from 1933 andin 1935 the production rights of the Atmos watch were transferred to Ets. Ed. Jaeger.
They concentrated 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, 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 only one degree Celsius winds the watch for 48 hours. This interesting winding mechanism is complemented by an exquisite movement of the utmost precision with a heavy torsion pendulum.
The condition for the accuracy of the clock is a stable and vibration-free installation.

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