Jaeger LeCoultre Atmos 561 by famed designer Marc Newson. Transparent Baccarat Crystal Bell-shaped Cabinet revealing horological movement within. Visible winding mechanism. Blue Aluminum Pointer. Completely hand manufactured.

The Atmos clock is both easy to maintain and functions in a quite extraordinary way. Indeed, the Atmos clock runs without battery, electricity or even winding, thanks to the inspired idea of Jean-Lon Reutter in 1928. At the tender age of 14, Jean-Lon Reutter spent his time trying to invent a perpetual clock. After graduating as an engineer from the prestigious Zurich Institute of Technology, he developed the principle of a clock that would keep time for centuries without any external intervention. In 1932, Reutter met David LeCoultre who put all his manufacturing resources into producing this incredible object.

The Atmos has been a huge success. Some 750,000 have been sold to date. It also has outstanding green credentials. Its mechanism is so environmentally-friendly that it would take 60 million to produce enough energy to light a single 15 watt bulb.

Using small temperature changes in the encapsulated environment for power, Atmos clocks can run for years without human intervention. Their power source is a hermetically sealed capsule containing a mixture of gas and liquid ethyl chloride, which expands into a chamber as the temperature rises, compressing a spiral spring; with a fall in temperature the gas condenses and the spring slackens. This motion constantly winds the mainspring. A variation in temperature of only one degree in the range between 15 and 30 degrees Celsius is sufficient for two days of operation

The Newson Atmos is the work of designer Marc Newson. The Australian artist, who came to fame with his Orgone stretch lounge chair, has applied contemporary design principles of pure lines and forms to envelop the Atmos 561 by Marc Newson in a Baccarat crystal ice-cube. It took five attempts to obtain this perfectly smooth crystal envelope.
Since 1833, when the inventive Charles Antoine LeCoultre established this venerable watchmaker, it has produced some of the most outstanding and innovative timepieces. It wasn't until 1931, however, that the Jaeger-LeCoultre brand rose to international fame. It was then that the Reverso - an ingenious reversible watch - was unveiled to the public.
