ATMOS

Invented in 1928 by Jean-Léon Reutter, and then perfected and manufactured by Jaeger-LeCoultre, the Atmos clock came close to fulfilling the ancient dream of perpetual motion. The Atmos extracts its energy from the slightest variations in temperature. For over half a century, this tiny technological marvel has been the official gift of the Swiss Confederation.

Time as measured by an Atmos clock entails dimensions beyond human understanding: the moon phase model loses only one day every 3821 years.
