The Atmos Hermes clock is the brainchild of three different companies: Hermes, Jaeger-LeCoultre, and Les Cristalleries de St. Louis. It has a crystal sphere that encases the clock’s movement. It is made by using a double overlay technique, which means it is crafted by coating layers of glass over each other.
The clock’s movement is not powered by a battery, electricity, or a winder. It operates by utilizing 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 pair of bellows, constantly winding the mechanism. A one-degree temperature change is enough to power the watch for 48 hours.
The Atmos Hermes clock is a limited edition. Only 176 units were produced.
