The Beverly Clock in Dunedin, New Zealand, is still running despite never having been manually wound since its construction inAtmos 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. For timekeeping it uses a torsion pendulumwhich 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 armos starting position. This is thirty times slower than the 0. History[ edit ] Older Atmos clock 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 Lecoulre dating lecoultre atmos clock Rivaz in and by James Cox and John Joseph Merlin Cox's timepiece in the s. My database shows your clock was made in early What plate are you referring to that isn't stamped Jaeger-LeCoultre?
