The Hermès Atmos Clock by Jaeger-LeCoultre.

A supreme melting pot of inventiveness, luxuriousness and artistic skills combine to produce something quite extraordinary, the Hermès Atmos Clock by Jaeger-LeCoultre.

An Atmos clock uniquely, never needs to be wound and providing it is carefully placed in a quiet spot and left undisturbed, will need no human intervention in order to maintain accuracy.  It has a movement which defies conventional clockmaking mechanics, one which integrates a gas-filled and sealed capsulewhich expands or contracts when the temperature around it changes, and in doing so powers the mainspring to which it is connected.  Even a one degree Celsius change in temperature is enough to give 48 hours of power.

This ingenious invention is largely unchanged since it was devised in 1928 - coincidentally, this was also the year when Hermès first outsourced the supply of movements to power timepieces which would be branded with their own name, finding in Jaeger-LeCoultre a perfect partner.  Les Cristalleries de Saint-Louis have also been involved with Hermès, providing them with handcrafted crystal objects to sell to their clients.  All three have contributedto this, the newest Atmos timepiece.

Such an originative mechanism should never be concealed, is deserving of a vitreous showcase, and like the memorable Marc Newson Atmos editions, also showcased in glass, the Hermès model features a unique handblown and hand-cut housing crafted by the master glassmakers at Les Cristalleries de Saint-Louis, which serves to both magnify and provide a look-see through to the workings.

In honour of the years that Hermès have been in existence, the Hermès Atmos Clock by Jaeger-LeCoultre will be limited to 176 pieces.
