Movement : The "watch that lives on air" uses the "breathing movements" of a gas-filled bellows created by temperature fluctuations to wind the movement.
Delivery : in protective packaging Jaeger-LeCoultre, with service intervention form, without original box, without original papers.
The movement of the watch is conspicuous by its cylindrical box on the back. Inside, a bellows-shaped expansion chamber contains chloroethyl, a gas that expands particularly strongly between 10 °C and 27 °C. The movement is then wound up.
A temperature difference of only one degree Celsius winds the watch for 48 hours. This interesting winding mechanism is complemented by an exquisite movement of the utmost precision with a heavy torsion pendulum.
The condition for the accuracy of the clock is a stable and vibration-free installation.
