Jaeger LeCoultre - Atmos Classique Phases de Lune

Dimensions: H x W x D: 22.5 x 19.5 x 15 cm

Description:
Atmos Classique Phases de Lune in gold-plated case.
White dial ring with black Roman numerals. White date ring with the months in French. Deep blue moon phase disc with golden moon and golden stars.
Serial number: 710594

Beautiful classic design, highest quality workmanship. Great technical look with the skeletonised dial, exposed gears and ruby bearings.
The front disk is pushed down at the top of the JLC button and can thus be removed.
The date is read on the XII.
On the VI we see the beautiful moon phase, which Jaeger LeCoultre claims has an accuracy of only one day difference in 3821 years.

Condition:
Movement new condition. Flawless 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-LeCoultrebegan.

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 Switzerland's official state gift to prominent visitors, e.g. politicians from abroad.
