By doing some research we learned:
Jaeger LeCoultre Atmos Clock Lives on Air. The Clock self-winds and keeps time on temperature change, perpetually spinning the pendulum. First invented in 1928 by Swiss Jean-Leon Reutter and Jaeger LeCoultre. For the past 50 years it has been the official gift of the Swiss Confederation.
Introduced in 1928 by Swiss engineer, Jean-Leon Reutter, who wanted to invent a clock that was powered by air, and would require no human intervention. He later sold the license to LeCoultre who perfected the clock to work by perpetual motion in 1936.
The frame and clock are made of gold-plated brass with clear glass windows. The face is white with goldtone metal Arabic numerals, hour markers and hands. There is a blocking lever at the base on the front used to lock the pendulum whenever the clock needs to be moved. There is also a water-level N inside in front of the pendulum to ensure that your clock is level (the air bubble should be in the center of the circle indicating it is level.
