Atmos V Kaliber 526 in the special version "Feuille d'Or". This model with the "Constellation" motif was built under Ref. Number 5802 from 1962-1975. Despite the rather long production time frame of 12 years, the watch appears relatively rarely in the trade.

Feuille d'Or means "leaf gold" translated from the French. The sides, the door and the glass on the top of the watch are painted from the inside. The golden paint looks astonishingly similar.

The white full number has a compass rose in the pivot point of the pointer. The entire motif of the watch is devoted to science and research into the earth and sky globe.
Length and latitudes run across all view areas of the watch. There are old world maps on the two sides. In the corners of the front -side door, we see researchers when studying and measuring the sky globe.

Useful information:
Even if Leonardo da Vinci could already prove that the production of a perpetuum mobile is physically impossible, it was always tried again and again. This also applies to the technology for a clock in 1928, whose energy source from the ambient air, which was obtained from the atmosphere, in 1928.
Since there were always problems with the clocks, the clockworks were made by Le Coultre et Cie in Switzerland from 1933 and in 1935 the production rights of the ATMOS clock became the ETS. Ed. Jaeger overwritten.
The technical principle of the works built by Jaeger Lecoultre from 1936 is simply captivating: in a hermetically sealed capsule there is a mixture of a liquid and the gas ethyl chloride. When the temperature rises, the mixture expands and when the temperature falls, it is pulling together, which moves a bellows in the pressure socket on the back of the watch like a couch harmonica. This movement continuously raises the clockwork. In the range between 15 and 30 ° C, a temperature change of a single degree Celsius is sufficient to provide the energy for about two days of two.
