Placing Your Atmos: Placing your Atmos clock is of extreme importance to ensure correct operation. Place your Atmos clock on an absolutely stable horizontal surface, where there is no risk of vibration or shock. Once started, the clock should not be moved unless absolutely vital. Cleaning the cabinet or the base should be carried out without handling or moving the clock. To set your Atmos clock to the right time it is of vital importance that only the minute hand if moved forward with one finger. Never turn the minute hand anti-clockwise and never touch the hour hand. Make sure that the balance is locked before setting your clock.

Lot Notes: 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.

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. This motion constantly winds the mainspring allowing the clock to run without any human intervention. 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.

Service: This clock can be serviced at extra cost to the buyer before purchasing with a 7-14 week estimated turn around time. However the clock is sold in excellent working condition.

Condition: Very Good – Excellent, very minor fretting to the two bottom corners of the front display glass (see photos) box has shelf wear.
