For centuries scientists had experimented with the idea of perpetual motion and watchmakers and clockmakers yearned for a timekeeping device that would work without the need of manual winding; in short a timepiece that would continue to run under its own power.
By the 1920's the closest they had come to this was the 400 day clock. In the late 1920s, Jean-Leon Reutter, a young Paris engineer produced a clock with a timekeeping mechanism designed specifically to consume the smallest possible amount of power to keep the clock running satisfactorily.
As well as changes to the mechanism, Reutter's clock included a mercury and gas filled bellows that would react to the most sensitive changes in temperature and atmospheric conditions, and in so doing, created a gentle rocking motion that gave power to the clock when needed.
The result of Reutter's achievement was an ingenious new clock that could run dependently and continuously, and so incredibly sensitive that it could be rewound by the slightest fluctuations in the atmosphere or by the slightest changes in temperature, hence the name 'Atmos Clock'. more...In 1930, Jaeger-Le Coultre a world famous Swiss watch-making company, also famous for the 'Reverso Watch' acquired the Atmos Clock Patent from Reutter and has continued to improve the design and manufacture the clocks to the present day.
An Atmos clock takes a month to produce in the factory, then another five weeks of trial and adjustment before it is ready for shipment
