Jaeger Lecoultre Atmos Watch

About the Item

Jaeger Lecoultre Atmos Watch Atmos VI Table clock It works correctly. perpetual motion It has caliber 528 (1958-1968) The dial is square Materials Bronze and glass The patina is golden and has some minor natural wear. Origin Switzerland Circa 1960 Atmos is the commercial name of a mechanical watch manufactured by Jaeger-LeCoultre in Switzerland whose peculiarity is that it does not need to be wound to operate, as it takes energy from changes in ambient temperature and atmospheric pressure. Can operate for years without human intervention Its power source is a hermetically sealed capsule containing a chloroethane gas-liquid mixture that expands in an expansion chamber when the temperature rises, compressing a coil spring; When the temperature drops, the gas condenses and the spring decompresses.1 This constant movement winds the mainspring. A single degree of temperature variation in the range of 15 to 30 degrees Celsius or a pressure variation of 3 mmHg is enough to keep the watch operational for two days.2​ For the watch to run with so little added energy, each piece of the mechanism must work with the least amount of friction possible. The regulating mechanism is a torsion pendulum, which consumes less energy than an ordinary pendulum. The torsion pendulum oscillates only twice per minute, which is 1/60 of the number of oscillations of a conventional pendulum clock.

Jaeger LeCoultre, Atmos Fontainebleu, Swiss Made in 1986
By Jaeger-LeCoultre
Located in Greven, DE
Jaeger LeCoultre - Atmos Fontainebleu Switzerland Year of construction 1986 Dimensions: H x W x D: 25 x 20 x 16 cm Description: Atmos calibre 540 in the rare "Fontainebleu" version in a wooden case. Square ring dial with rounded corners. Roman numerals for hours, fine minute track, Breguet hands with counterweights. "SWISS MADE" is printed below the 6. A manufacturer's engraving and the calibre number can be found on the front movement plate. A "Jaeger LeCoultre" imprint can be seen at the bottom right of the front disc. The Atmos Fontainebleu was listed in the collection from 1987. It was available in various versions - with a square or round dial, with a moon phase, with a black lacquered or mahogany case. Although the clock offered here dates from 1986, it was only listed in the 1987 and 1988 catalogues. Ref. 220.030.4 Serial number: 620514 Year of manufacture: 1986. Condition: Freshly overhauled, very good condition of the movement. Flawless case condition. Interesting facts: Generations of inventors have endeavoured to construct a perpetual motion machine - and one after the other was disappointed to discover that their designs did not work. Today we know that it is technically impossible to build a machine that works continuously without consuming energy. Apart from wear and tear, a machine only works as long as it is supplied with energy: Electricity, gas, petrol... Without human intervention and practically without wear and tear, the Atmos does not run without energy consumption, but it is fed by an energy source that can be described as "eternal": It draws its energy from the constant fluctuations in air temperature. The Atmos literally lives from the air. In order to utilise the temperature fluctuations as an energy source, a suitable medium had to be found. The choice fell on ethyl chloride (C2H5Cl) - a substance that dentists know as an anaesthetic. Ethyl chloride has a very high coefficient of thermal expansion between 10 and 27°C, i.e. the volume change is particularly large in this temperature range. The round can...
