Since this clock is now tuned for time at high altitude, if the new owner lives at a lower altitude, some necessary calibration upon arrival at the destination might be required.After shipping, the Atmos clock might need some adjustment.If you move the Atmos clock from one room to the other,Please make sure to lock the balance wheel before doing any moving and adjustments.The adjustments of the liquid level may be needed after each move.Even if noted as working great, due to its age, it might need service anytime.Please understand that due to the delicate nature of these Atmos clock adjustments may be needed after each move.We have shipped a number of these fine Atmos clocks to various countries without any damage problems.The balance wheel(pendulum) will be locked carefully, and the clock packed with double boxes, ship with full coverage insurance to USA 48 States ONLY.

In 1928, Neuchatel engineer Jean Leon Reuter invented the technology for a clock whose energy source was drawn from the ambient air, from the atmosphere so to speak.As there were repeated problems with the watches, the movements were manufactured by Le Coultre et Cie in Switzerland from 1933 and in 1935 the production rights for the Atmos watch were transferred to Ets. Ed. Jaeger in 1935.The technical principle of the movements built by Jaeger Le Coultre from 1936 onwards is simply captivating: a mixture of a liquid and ethyl chloride gas is contained in a hermetically sealed capsule. As the temperature rises, the mixture expands, and as the temperature falls, it contracts, causing a bellows in the pressure box on the back of the watch to move like an accordion. This movement continuously winds up the movement. In the range between 15 and 30?C, a change in temperature of just one degree Celsius is enough to provide the energy for around two days of running time. (Condition: New (Other))
