Clocks and watches move up one hour in Europe in the middle of the night of March 29th, a perfect time to introduce a new interpretation of Jaeger-LeCoultre’s groundbreaking Atmos clock, which was invented in 1928 by Jean-Léon Reutter bringing to life the invention of the utmost perpetual movement, a dream of physicists for centuries. The Atmos seems to defy the laws of physics: running independently of human intervention, it draws its energy from infinitesimal variations in the ambient air temperature. The secret lies in a hermetically sealed, gas-filled capsule, which is connected to the clock’s drive spring by a membrane. The house introduced the Atmos Infinite in 2022 and in late 2025 has released the Atmos Infinite Halo,  in a limited edition of 100 pieces with a white lacquer dial. 

Born in 1928, the Atmos is a clock like no other. An invention made possible by the extensive savoir-faire of the Jaeger- LeCoultre Manufacture’s watchmakers, the Atmos appears to defy the laws of physics, running for centuries without the need for any conventional energy source or rewinding. Instead, its mechanism is powered by normal, everyday fluctuations in air temperature; a variation of just one degree Celsius is sufficient to guarantee two days of running time. Since the 1930s, Jaeger-LeCoultre has harnessed the Manufacture’s watchmaking skills to continually make technical improvements, and its creative talents to enhance what has become a prized objet d’art. While the glass cube based on the Art Deco design of the Atmos II has become an instantly recognizable classic, Jaeger-LeCoultre has also collaborated with renowned designers and master artisans to create special editions of the Atmos. ©Trish Valicenti for The Gourmet Gazette https://www.jaeger-lecoultre.com/us-en
