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.
The limited edition Atmos clock lives from the air of time. Within a sealed capsule, a mixture of gases expand and contract with each temperature change. Thus, the mechanism winds naturally, without any human intervention.
