Originally invented in 1928 by Jean- Léon Reutter, the Atmos clock was further perfected and manufactured by Jaeger LeCoultre, a brand that was a result of an invention. The Atmos clock collection from Jaeger LeCoultre is a product of the brand’s continued dedication and hard work towards perfecting the original clock developed by Reutter. Technically astounding, the Atmos clock houses a hermetically sealed capsule that winds the mainspring converting thermal energy into mechanical energy. Basically, the clock gets its power from the minute changes in the atmospheric temperature. Offering utmost precision with wear-free functionality, the Atmos clocks are a joy to own, enjoying a service life of an amazing 600 years without the need of an external power source, whether hand-wound or suspended pendulum-like weights. Hand-crafted to precision, Jaeger LeCoultre’s Atmos collection of clocks is elegantly designed with precious metals and traditional craftsmanship with some models taking a whole month to be produced. With a close encounter to fulfilling the ancient dream of perpetual motion, the Atmos basically extracts energy from the slightest variations in the temperature. A true testament of Jaeger LeCoultre’s Swiss artistry, the Atmos clock is thoroughly checked for quality and execution before it is allowed to leave the workshop. Jaeger LeCoultre’s Atmos clocks are synonymous with royalty and great statesmanship having been associated with great people like John F. Kennedy, Sir Winston Churchill and Charlie Chaplin. In addition to this, Jaeger LeCoultre has also been the official gift of the Swiss Confederaration for over half a century.
