Jaeger LeCoultre Unveils The Atmos Hermès Clock

Arguably the most celebrated and exclusive collaboration of recent times, Jaeger LeCoultre, Hermès and Les Cristalleries de Saint-Louis united to produce a 176-piece limited edition masterpiece – The Atmos Clock.

Invented in 1928 by Jean-Léon Reutter, and perfected by Jaeger LeCoultre, the Atmos Clock is a mastery of perpetual motion operating with no battery, no electric current and no winding. It extracts energy from a hermetically sealed capsule containing a mixture of gases that expands when the temperature rises and contracts when it drops. Connected to the mainspring of the clock, the capsule acts like a concertina of bellows, thereby constantly winding the movement. Comprised of 190 precision-assembled parts, it is so sensitive that a one degree temperature difference is enough to power it for 48 hours.

Equally impressive on the outside, Les Cristalleries de Saint-Louis glass makers have created a crystal globe using the so-called doublé or double overlay technique, which consists of coating layers of glass over each other, including a colored one. Cristalleries has only six master glassmakers with the ability required to perform this task.

The Atmos Clock is exclusively available at Hermès.
