Atmos is the brand name of a mechanical clock manufactured by Jaeger-LeCoultre, which does not need to be wound. It derives energy from smalltemperaturechanges andatmospheric pressurechanges in the environment, and can run for years without human intervention.
The first Atmos clock was designed by Jean-Léon Reutter, an engineer inNeuchâtel, Switzerland, in 1928. Driven by amercury-in-glassexpansion device. The mechanism operated on temperature changes alone. A one degree change in air temperature will wind an Atmos Clock for two days.
In 1929,Compagnie Générale de Radio(CGR) in France began manufacturing the first commercial model, Atmos 1, which used a mercury source. In 1935, Jaeger-LeCoultre took over production of Atmos 1 while it developed a second design which used the presentethyl chloridepower source. To date, over 600,000 Atmos clocks have been produced.
Every Atmos clock is still made in Switzerland entirely by hand. A single Atmos clock takes a month to produce and then undergoes another 5 weeks of trial and adjustment before leaving the factory. This clock is a technological wonder. Inside a sealed capsule, a mixture of gas and liquid expands as the temperature rises and contracts as it falls, moving the capsule back and forth like a tiny unseen accordion. This motion is used to constantly wind the mainspring thus enabling the clock to run and keep perfect time. Such variation occurs naturally in normal room temperature and thus without any additional sources of energy, the Atmos clock will continue to run, if left untouched, "forever". The parts inside the Atmos are virtually wear free, allowing an Atmos to have an operational service life of over 600 years.Copy and paste this link to see a video showing this clock running. with Mobile
