Jaeger-Le Coultre's famous 'Atmos' clock was first developed in 1928. The clock is automatically wound without any intervention by the owner. Changes in air temperature make winding the clock's mainspring. A change in temperature of one degree can provide enough power to run the clock for a few days, and the mainspring has enough power in reserve to run the clock for a year. Energy is conserved by the very slow-moving twisting pendulum which 'beats' only twice per minute.
"JLC ATMOS clock is one of the world’s most innovative clocks, the Jaeger-LeCoultre Atmos is a visionary technical masterpiece. Powered by atmospheric pressure and temperature changes, it’s essentially a perpetual motion device, allowing it to run for years without human intervention. The Atmos is such a ground-breaking creation that it’s chosen as a traditional gift to heads of state and dignitaries".
The movement is very silent.
Warning!!! These clocks can have troubles to wind in premises with high-quality climate control systems (where the air temperature is very stable).
The clock must not be moved without locking the pendulum - moving the lever at the base bottom from the left to the right.
To change the time, the minute hand must be moved by turning it clockwise.
