Jaeger-Le Coultre's famous 'Atmos' clock was first developed in1928. The clock is automatically wound without any intervention by the owner. Changes in air temperature makes winding theclock's mainspring. A change in temperature of one degree can provide enough power to run the clock for few days, and themainspring 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 perminute. The movement is very silent.
Warning!!! These clocks can have troubles to wind in premises with high quality climate control systems (where air temperature is very stable).
The clock must not be moved without locking the pendulum - moving the lever at case bottom from the left to the right.
To change the time, the minute hand must be moved by turning it clockwise.
