Powered by tiny changes in atmospheric temperature, the Atmos runs on an incredibly low amount of energy – it would take 60 million Atmos clocks to light one 15-watt bulb. While Reutter’s ingenious idea originally called for mercury contained inside a glass capsule, now the secret lies in a sealed, cylindrical bellows that contains ethyl chloride, a gas highly reactive to variations in temperature. It expands and contracts constantly even with the slightest change in the ambient temperature. This in turn causes the bellows to expand and contract, winding the mainspring of the clock.
Because the balance of the Atmos beats at a languid two oscillations per minute – compared to 480 per minute for an average wristwatch which requires 250 times more energy than an Atmos – a one degree Celsius change in temperature is enough to keep the clock going for two days.
The Atmos is an extraordinarily energy efficient timekeeper and in theory could run for decades, if not centuries, without intervention. But of course atmospheric pollution, moisture, wear and tear will eventually take their toll, though Atmos clocks have been known to slowly tick along soundly for 20 or 30 years.
Though the construction and mechanism of the Atmos has remained largely the same throughout its 80 year production, Jaeger-LeCoultre has expanded the Atmos range to a surprising variety of clocks.
