Description
Description: Beautiful brushed chrome and glass. The face is square and also brushed chrome with black trim. The timepiece is atmospheric. Has a leveling guide. Works by atmospheric change
History: 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.Its power source is an internal hermetically sealed capsule containing a mixture of gaseous and liquid ethyl chloride, which expands into an expansion 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 temperature variation of only one degree in the range between 15 and 30 degrees Celsius, or a pressure variation of 3 mmHg, is sufficient for two days' operation.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 executes only two torsional oscillations per minute, which is 1/30th the rate of the pendulum in a grandfather clock.

Condition
Update: Changed to good condition, we found two screws are missing off the top right hinge of cover, does not affect closing of top, no broken glass or scratches on the entire surface. Level the clock with the built in spirit level, then it will automatically start working.
