Jaeger LeCoultre - Atmos Feuille d'or Motif Constellation

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

Description:
Atmos V calibre 526 in the special "Feuille d'or" version. This model with the "Constellation" motif was produced from 1962 to 1975 under the reference number 5802. Despite the rather long production period of almost 13 years, the clock appears relatively rarely on the market.

Feuille d'or translates from French as "gold leaf". The sides, the door and the glass on the top plate of the clock are lacquered on the inside. The golden lacquering looks strikingly similar to gold leaf.

The white full dial has a compass rose in the centre of the hands. The entire motif of the clock is dedicated to science and the exploration of the terrestrial and celestial globe.
Lines of longitude and latitude run across all faces of the clock. There are old world maps on the two sides. In the corners of the front door we see researchers studying and measuring the celestial globe.

Serial number: 251836
Year of manufacture: 1967

Condition:
The movement has been freshly overhauled and runs very accurately and reliably. The case is in absolutely authentic original condition with age-appropriate craquelure of the gilding.

I give a one-year guarantee on the movement if it is set up and handled correctly.

Worth knowing:
Even though Leonardo da Vinci was able to prove that the production of a perpetual motion machine is physically impossible, it has been attempted time and again. This was also the case with the Neuchâtel engineer Jean Leon Reuter, who in 1928 invented the technology for a clock whose energy source was drawn from the ambient air, from the atmosphere so to speak.
As there were repeated problems with the watches, the movements were manufactured by Le Coultre et Cie in Switzerland from 1933 and in 1935 the production rights for the Atmos watch were transferred to Ets. Ed. Jaeger in 1935.
The technical principle of the movements built by Jaeger LeCoultre from 1936 onwards is simply captivating: a mixture of a liquid and ethyl chloride gas is contained in a hermetically sealed capsule. As the temperature rises, the mixture expands, and as the temperature falls, it contracts, causing a bellows in the pressure box on the back of the watch to move like an accordion. This movement continuously winds up the movement. In the range between 15 and 30°C, a change in temperature of just one degree Celsius is enough to provide the energy for approximately two days of running time.
