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.
