1980's Jaeger-LeCoulte Atmos 540 Clock
SOLD $1,100.00 Sold: Jan 8, 2025 on eBayOriginal Listing Description
ATMOS 540 c. 1985 still with packing - never opened. New, no box.The ATMOS from Jaeger LeCoultre is a unique mechanical clock. This pendulum clock has been available for purchase since the early 1930s and is still sold today—almost identical in JLC.The ATMOS clock uses the smallest temperature fluctuations to continuously generate energy and maintain a power reserve.Behind the extremely smooth-running movement is a hermetically sealed pressure can filled with ethyl chloride, which reacts extremely sensitively to temperature fluctuations and thus generates movement via a metal bellows: if the temperature rises, the gas in the pressure can expands and vice versa. This pressure difference drives a mechanism that in turn winds the clock. A temperature change of just one degree can generate enough energy to keep the clock going for two days. The clock therefore does not need to be wound by hand and will run almost indefinitely as long as it is exposed to the natural fluctuations of the ambient temperature.Jaeger LeCoultre’s ATMOS is not only a technical jewel, but also an aesthetic one. It combines traditional craftsmanship and innovative technology to create a timepiece that measures time naturally and delights clock lovers around the world. (Condition: Brand New)
