DESCRIPTION

  • The Atmos, operating principles.

    It was in 1928 that the Neuchâtel engineer Jean-Léon Reutter patented his design for a mechanism that ran on variations in pressure. The Atmos’s high-precision movement lives on air alone: that is, its sole source of energy is variations in the ambient air temperature. Each time the latter rises or falls by a single degree centigrade, the mechanism is able to store up enough energy to guarantee 48 hours of function. Its secret' A hermetically sealed gas-filled capsule which expands when the temperature rises and contracts when it drops: each time it does so it winds the clock’s mainspring. Drawing its inspiration from a brilliant invention, the Atmos has practically achieved perpetual motion.

    Needless to say, the construction of this unique clock is an operation requiring extreme precision. In order to limit energy waste and reduce wear, the movement functions without lubricant – the friction of the latter on the gearwheels would be enough to bring the mechanism to a standstill. A few comparisons will suffice to illustrate the extraordinary technical achievement that is the Atmos: for instance, it may be the largest mechanism produced by Jaeger-LeCoultre, but its energy consumption is actually considerably less than that of the Calibre 101, the smallest watch movement of all time, also produced by the  Manufacture. The Atmos uses scarcely a 240th part of the energy required by an ordinary wristwatch. Or, more vividly still, imagine this: it would take 60 million Atmos clocks to equal the energy consumption of a single 15-watt electric light bulb.
