An Atmos clock consists of a hermetically sealed capsule that contains ethyl chloride, which is a combination of gas and liquid that expands and contracts according to the temperature, forcing air through the mechanisms inside.
In 1928, Jean-Léon Reutter, a Swiss engineer, built the first Atmos prototype, which used a mercury-in-glass expansion device that utilized temperature alone rather than temperature combined with atmospheric pressure.
Building upon a foundation laid more than two centuries ago, Jaeger Lecoultre (JL) has created a marvel of engineering in the Atmos that continues to evolve aesthetically and technologically.
Conceptualized by Australian designer, Marc Newson, JL's latest Atmos features the new 566 caliber movement housed inside an elegant, bubble-shaped Baccarat crystal cabinet.

A year later, a French company commercially manufactured the Atmos 1, which functioned by way of a mercury and ammonia bellows power system.
This Jaeger Lecoultre Atmos also has a new movement that displays northern hemisphere constellations through a large opening.
Since the very first Atmos hit the market in 1939, JL has continuously produced new versions of this emblematic timepiece.
In 1935, JL took over the Atmos project and developed the first ethyl chloride model in 1936.
Atmos clocks are almost perpetual motion machines that never need winding or adjusting.
