About the Item

Early Atmos clock from Jaeger LeCoultre Switzerland Brass, partly gold-plated Year of manufacture 1950 Dimensions: H x W x D: 23.5 x 21 x 16.5 cm Description: Atmos II in matt brushed case. Blued screws, knurled screw on the front for regulating the rate, rotating pendulum with fine vertical stripes divided into 8 segments. Dial ring with the old, original and slightly tarnished paintwork. As is usual with the early dials - with horizontal 3 and horizontal 9. Unlike today's models, this early Atmos clock still had two serial numbers. One for the case and one for the movement. The serial number of the case can still be read from the top in the usual place: 21989. The serial number of the movement can be read from the front on the plate: 22717. Year of manufacture: 1950 The rate of the Atmos clocks was initially set using a regulating screw from behind above the pressure box. Because the regulating screw was often damaged when the glass cover was lifted, it was moved to the front, in front of the pressure box, in the early 1950s. After a few years, this position was also deemed impractical and from then on the adjustment was made by means of a slide between the movement and the pressure box. This is still the case today. A very beautiful and absolutely rare clock with a regulating screw that can be operated from the front! Condition: The clock has been freshly overhauled and runs absolutely reliably and accurately. The photos are not "embellished", the case condition is as shown in the photos. 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 concluded 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 watches, 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 the era of the Atmos from Jaeger-LeCoultre began in 1938. 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 watch 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.

The best-known timepiece in the company's modern collection is the Master Control watch, unveiled in 1992. It symbolizes a return to the thin style and performance-first ethic of classic Jaeger-LeCoultre. In 2018, the watchmaker also launched the Polaris collection. Inspired by the original Memovox, the series features a sporty, elegant and contemporary look.
