Classic Atmos Clock with Roman Numerals

Dimensions: H x W x D: 22 x 18 x 13.5 cm

Description:
Atmos V calibre 526 in gold-plated brass case.
White dial ring with Roman numerals and Breguet hands. Golden, five-sided glazed case. The watch was first presented in this version under ref. no. 5833 in 1969 and then manufactured from 1972 to 1985.

Serial number: 564303
Year of manufacture: 1983

Condition:
Beautiful preservation of the original gilding with some signs of wear on the back not visible from the front. The condition of the back is clearly visible in one of the photos. The movement runs absolutely accurate and reliable.

I give a one year warranty on the functionality of the movement when properly set up and handled.

Fun 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 movement of the clock 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.

Also worth mentioning is the absolute environmental friendliness of the clock, which, despite its unlimited running time, does not need a battery or any other electrical drive.
For decades, the Atmos has been Switzerland's official state gift to prominent visitors, e.g. politicians from abroad.
