Jaeger LeCoultre, Atmos Marina Poissons from 1962

About the Item

Jaeger LeCoultre - Atmos "Poissons Switzerland Brass, plexiglass Year of manufacture 1962 Dimensions: H x W x D: 22.5 x 18 x 13.5 cm Description: The Atmos V Calibre 526 was produced in various special models. The white colour is called opal. The model "Marina" offered here was released under the model name Plexi grave Poissons with the ref no 5810. The watch is also known under the names "Pisces" or "Aquarium". The detailed photos clearly show how wonderfully three-dimensional the fish, air bubbles and water plants appear. This effect is created because the engravings have been deeply engraved into the thick outer plexiglass panes and then painted by hand. White dial with Arabic numerals 3, 6, 9, 12 and eight indexes. Serial number: 152483 Year of manufacture: 1962 Condition: Absolutely accurate. Movement runs perfectly and reliably. Case with slight signs of wear. The photos are not "embellished", the case condition is as shown in the photos. Many comparable models have "frosty" discs, i.e. the plexiglass has become brittle due to UV radiation. Not so in this case, all the panes are preserved in super condition! Interesting facts: In 1927, the young engineer Jean-Léon Reutter presented the prototype of the Atmos watch he had developed. The response in the press was great and so he signed a contract with the Compagnie générale de radiologie, which built and distributed the "Atmos I" under Reutter's direction from 1930. Since there were always problems with the watches, the movements were manufactured by Le Coultre et Cie inSwitzerland from 1933 andin 1935 the production rights of the Atmos watch were transferred to Ets. Ed. Jaeger. They concentrated on developing a simpler and more robust engine and from 1938 the era of the Atmos by Jaeger-LeCoultre began. The "watch 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 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. 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 the official state gift of Switzerland to prominent visitors, e.g. politicians from abroad. [Source: Jean Lebet - Living on Air / Jürgen Abeler - Ullstein Uhrenbuch].
