Jaeger LeCoultre Atmos Baby 526-5

The Jaeger-LeCoultre Atmos 526-5 is a Swiss mechanical table clock powered by changes in ambient temperature rather than conventional manual winding. Its Calibre 526-5 movement uses a sealed pressure capsule to convert small temperature fluctuations into energy, which is transferred through the winding mechanism to maintain tension in the mainspring. The movement incorporates a torsion pendulum designed for extremely low energy consumption.

The 526-5 was produced across multiple decades and is found with variations in case finish, dial configuration, and production details. Examples are documented from the 1950s through the 1970s, including five-sided glazed cases with gilt or plated brass construction and white dials with applied Arabic numerals and baton markers.
