About the Item

Atmos II from Jaeger LeCoultre Switzerland Nickel-plated brass Year of manufacture 1950 Dimensions: H x W x D: 23.5 x 21 x 16.5 cm Description: Atmos II in a new nickel-plated case. Removable glass bell, blued screws, rotating pendulum with small round recesses. Regulation by means of a slide between movement and pressure box. Dial ring with horizontal 3 and horizontal 9. Serial number: 32653 Year of manufacture: 1950 A second number is engraved under the serial number: 11908 Condition: The clock has been freshly overhauled and runs absolutely reliably and accurately. The case and movement have been newly nickel-plated and are in mint condition. Interesting facts: In 1927, the young engineer Jean-Léon Reutter presented the prototype of the Atmos clock 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 sold the "Atmos I" from 1930 under Reutter's direction. As there were repeated problems with the clocks, the movements were manufactured by Le Coultre et Cie in Switzerland from 1933 and in 1935 the production rights for the Atmos clock were transferred to Ets. Ed. Jaeger in 1935. The focus was on developing a simpler and more robust motor, and from 1938 the era of the Atmos by Jaeger-LeCoultre began. The "clock that lives from the air" uses the "breathing movements" of a gas-filled bellows caused by temperature fluctuations to wind the movement. The movement of the clock stands out with 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. A temperature difference of just one degree Celsius winds the watch for 48 hours. This interesting winding mechanism is complemented by an exquisite movement of extreme precision with a heavy torsion pendulum (rotating 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 require 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. [Source: Jean Lebet - Living on Air / Jürgen Abeler - Ullstein Uhrenbuch]

Jaeger-LeCoultre

The exquisite art of watchmaking is on display in the distinctive designs of Jaeger-LeCoultre. The Swiss manufacturer is celebrated for its striking Art Deco–era antique clocks, while its range of sumptuous luxury watches spans the gamut of modern design, each one a time capsule of its period.

Jaeger-LeCoultre was established in 1833 by watchmaker Antoine LeCoultre in the Vallée de Joux of the Swiss mountains. LeCoultre was also an inventor who, in 1844, created the millionomètre. As the first instrument to measure thousandths of a millimeter with total accuracy, it refined the meticulous watchmaking process. By 1866, LeCoultre's son, Elie LeCoultre, took over the business. He revolutionized watchmaking by bringing all 180 skills involved in the trade into one workshop: LeCoultre & Cie Manufacture.

By 1903, the company had passed to Antoine LeCoultre's grandson, Jacques-David LeCoultre. He created a signature line of ultra-thin watches in partnership with Edmond Jaeger, a French watchmaker who specialized in flat watch cases. In 1907, Louis Cartier signed a contract with Jaeger so that Cartier would have movements for its popular timepieces produced exclusively at LeCoultre in Switzerland. This era saw the debut of Cartier’s Santos as well as its Tank watch.

Watchmakers at Jaeger-LeCoultre began to experiment with the Art Deco style that had encompassed the 1920s and the 1930s. At the time, there were many influences that led to the creation of Art Deco jewelry, while the cases of Art Deco clocks featured architectural details and saw an integration of materials such as brass, glass and marble. Iconic Jaeger-LeCoultre designs from this era include the 1928 Atmos clock and the Reverso watch. Stylish and practical, the coveted Reverso watch features a case that you can flip to protect the watch face.

During the 1950s and '60s, Jaeger-LeCoultre watchmakers continued the manufacturer’s tradition of prioritizing practical reliability. In 1958, the company introduced the robust and durable Geophysic watch collection. The Memovox Polaris, an alarm-equipped dive watch one could wear underwater, followed in 1968.
