Long-standing french fashion house Hermès joined forces with watch and clockmaker Jaeger-LeCoultre and Cristalleries de Saint-Louis for a supreme demonstration of art, craftsmanship and engineering. The perforated crystall glass globe is quipped with an amazing mechanism. A quasi-perpetuum mobile, the Atmos pendulum made by Jaeger-LeCoultre is filled with a special gas mixture, which expands with rising and deflates with falling temperatures, winding up the movement and thus keeping the clock running. A fluctuation of just one degree is enough to supply the clock with enough energy for 48 hours. The Atmos clock comes in a limited run of only 176 is exclusively available via Hermès.
