The Atmos: A Perpetual Mechanical Movement Powered by Temperature Changes

Encased in a beautiful Saint-Louis crystal sphere, the Jaeger-LeCoultre Atmos movement is a marvel of engineering. First developed in 1928, it operates solely on changes in ambient air temperature. A mere one-degree Celsius fluctuation generates enough energy to power the clock for two to three days, eliminating the need for batteries or manual winding. It stands as a testament to Jaeger-LeCoultre's signature innovation and creativity.

This clock has previously been presented as an official gift to the Swiss Federal Assembly and gifted to celebrities worldwide. Now, it enters a new chapter through a collaboration with Hermès and Saint-Louis, French Maisons that embody history and esprit. The result is the Atmos Hermès.

The Atmos Hermès represents a harmonious blend of advanced techniques, tradition, and innovation, cultivated over the long histories of its creators: Jaeger-LeCoultre, celebrating its 180th anniversary this year; Hermès, with 176 years of heritage; and Saint-Louis, boasting 427 years of craftsmanship. The clock will be available at the Jaeger-LeCoultre boutique in Mitsukoshi Nihonbashi and Hermès boutiques.
