Jaeger-LeCoultre Atmos Clock, Cal. 526 Classic, Midcentury, 1966



Jaeger-LeCoultre - Atmos Classic Clock, cal. 526 Switzerland brass gold-plated Year of manufacture 1966 Dimensions: H x W x D 22 x 18 x 13,5 cm Description: Atmos V Caliber 526 in a gold-plated brass case. Classic white dial ring with Arabic numerals. Serial number: 222082 Year of construction: 1966 Condition: Revised, perfect factory condition. Absolute accuracy. Worth knowing: In 1927 the young engineer Jean-Léon Reutter invented the functional principle of the Atmos watch. He used the "breathing movements" of a gas-filled bellows, which occur when the temperature changes, to wind the movement. The Jaeger LeCoultre company used this principle to build the Atmos watch in series production from 1928 onwards. The movement of the watch stands out due to its cylindrical box on the back. Inside it, a bellows-like Expansion chamber contains chloroethyl, a gas that expands particularly strongly between 10 °C and 27 °C. A temperature difference of only 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 (rotating pendulum). The condition for the accuracy of the clock is a stabile and vibration-free installation. The watch is also extremely environmentally friendly, and despite its unlimited running time, does not require a battery or any other electrical drive. The Atmos has been Switzerland's official state gift to prominent visitors, e.g. politicians from abroad, for decades.
