Jaeger LeCoultre Atmos watch in plexiglass case

Dimensions: H x W x D: 23.5 x 20.5 x 16 cm.

Description:
Atmos calibre 526 in a glass/plexiglass case with gold-plated base and crossbars.
White dial ring with gold numerals and hour markers.
Serial number: 116841
Year of manufacture: 1958

Condition:
Beautiful condition. The movement is freshly overhauled and runs perfectly and reliably.
The photos are not "embellished", the case condition is as shown in the photos. In some photos the clock is shown without the faceplate, due to the reflection of the flash when the photo was taken.
The base and the crossbars at the top of the case are newly gilded.

Interesting facts:
The "clock that lives on air" uses the "breathing movements" of a gas-filled bellows created by temperature fluctuations to wind the movement.
The clock's movement stands out because of 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.
A temperature difference of just one degree Celsius winds the watch for 48 hours. This interesting winding mechanism is complemented by an excellent 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.
