What inspiration led the Jaeger‑LeCoultre watchmakers to dream up the Atmos clock in 1928? How did they think to use variations in temperature to power it? The Atmos clock still surprises people today because of its inventiveness. Within a sealed capsule, a mixture of gas expand and contract with each temperature change. Thus, the mechanism winds naturally, without any human intervention. The subtle union between the classic and the modern is the secret to the Atmos collection’s timelessness. Its unique design allows the observer to see the complexity of its machinery from all angles. It is a tribute to the very first Atmos clock and its avant-garde nature. From Art Déco through to contemporary art, the rare crafts and complexities of watchmaking, the Atmos has always kept up with the times, while maintaining its soul thanks to the reinterpretations of great designers working together with Jaeger-LeCoultre.
