An attractive French mantel clock with a silk suspension in the ‘Pendule portative’ style with a decorative carrying handle. The glass is removed to wind the clock and unusually it is removed from the right hand side. The dial is vitreous enamel showing the makers name and Roman numerals, it does have slight hairlines to the corners as can be seen in the pictures but you have to be very close to see them. If the new owner would like these permanently removed, it can be arranged for an extra cost. Personally I would leave them as they are really are faint. The clock is of 7 day duration and has a bell strike for the hour and the half hour. The case is ebonised with brass inlays of geometric style. A glass aperture to the top and one to each side. The rear door opens to reveal a fully overhauled mechanism. The clock was made and retailed by J.

Atmos is the brand name of a mechanical torsion pendulum clock manufactured by Jaeger-LeCoultre in Switzerland which does not need to be wound manually. It gets the energy it needs to run from temperature and atmospheric pressure changes in the environment, and can run for years without human intervention. The clock is driven by a mainspring, which is wound by the expansion and contraction of liquid and gaseous ethyl chloride in an internal hermetically sealed bellows.

The ethyl chloride vaporises into an expansion chamber as the temperature rises, compressing a spiral spring; with a fall in temperature the gas condenses and the spring slackens. In order to run the clock on this small amount of energy, everything inside the Atmos has to work in as friction-free a manner as possible. For timekeeping it uses a torsion pendulum , which consumes less energy than an ordinary pendulum. The torsion pendulum has a period of precisely one minute; thirty seconds to rotate in one direction and thirty seconds to return to the starting position.

This is thirty times slower than the 0. The first clock powered by changes in atmospheric pressure and temperature was invented by Cornelis Drebbel in the early seventeenth century. It is mentioned in two works of Ben Jonson. Clocks powered by atmospheric pressure and temperature changes were subsequently developed by Pierre de Rivaz in , [2] and by James Cox and John Joseph Merlin Cox’s timepiece in the s. The Beverly Clock in Dunedin, New Zealand, is still running despite never having been manually wound since its construction in The mechanism operated on temperature changes alone.

The watch that keeps up with the times. What inspiration led the Jaeger‑​LeCoultre watchmakers to dream up the Atmos clock in ? How did they think to use.

Atmos clocks are known as perpetual motion clocks, as they require no winding. They work by using a thin hairspring located at the top of the clock and an aneroid chamber mounted on the back of the movement via which the clock is able to detect changes in temperature which regulates the accuracy of the movement. Apparently even a one degree change in temperature is sufficient to wind the clock for two days’ duration. The brass clock is housed inside a gilt metal framed glass case with front opening door.

The clock has a white chapter ring dial through which you can see the movement; this is surrounded by a gilt brass bezel. The dial has both Arabic numerals and baton hours and features two gilt, dagger style hands with blackened tips.

Cased Atmos Clock By Jaeger LeCoultre c’s ~. A very stylish Swiss-made Atmos Clock by Jaeger LeCoultre complete with case dating to the late ‘s.

T he “Atmos” brand clock is an ingenius contraption that comes closest yet to being a “perpetual motion” machine. It is a mechanical clock Produced by the Swiss firm of Jaeger-LeCoultre, it is a mechanical clock that runs without needing anyone to wind it up periodically. It runs on the energy produced by natural changes in temperature and barometric pressure in its environment. Left undisturbed it can run accurately for years without the need for winding from the outside. You’ll never lose a winding key with this clock – it doesn’t have one!

It’s powered by the natural expansion and contraction of a mixture of gas and liquid ethyl chloirde contained in a sealed capsule. When the clock’s surrounding temperature rises the gas expands into an expansion chamber which causes a spiral spring to be compressed. When the temperature falls the gas condenses, relieving pressure against the spring.

This constant expansion and contraction of the spring keeps the mainspring wound, eliminating the need for human intervention. A one degree change in temperature between 59 and 86 degrees Fahrenheit 15 to 30 degrees Celcius is enough to power the clock for two days.
