Jaeger-Lecoultre Atmos Birth Date Phase De Lune 22cm x 20cm x 15cm Q5145204 (2009)

The origins of the Atmos clock date back to 1928, when it was invented by the Neuchâtel-born engineer Jean-Léon Reutter, who had been fascinated since his earliest youth by the myth of perpetual motion. His incredible mechanism, based on a system that is still in the avant-garde today, was subsequently taken up by Jacques-David LeCoultre.
Nearly 100 years after its invention, the operating principle of the Atmos remains unique in the world. The clock draws the energy required to operate from tiny variations in temperature resulting in the contraction or expansion of a gas contained within an airtight bellows that dilates and retracts in turn. The incessant repetition of this phenomenon can be compared with breathing, and the to-and-fro motion winds a barrel that drives a mechanism requiring an exceptionally small amount of energy – since a one-degree variation is enough to keep it running for 48 hours.

An Atmos consumes 250 times less energy than a standard mechanical wristwatch. This sparing attitude makes the Atmos clock the least energy-consuming mechanism ever invented. The privilege of slowness also lies in the almost total absence of wear and thus aging of this mechanism that appears to literally live on air and which, 100 years after its birth, is still the closest any object has ever come to perpetual motion.
