Original Listing Description

This is a beautiful Atmos clock, made and sold by Jaeger Le Coultre, a well known Swiss company. It is in excellent condition for it's age, both cosmetically and mechanically. It is in good running order and keeping time. It is an unusual 2 tone design. This one, I believe, is a Calibre Series II. It is running beautifully and keeping excellent time.I've had mixed opinions from Atmos enthusiasts about the nickel/chrome plating, on it's originality. I don't have a reason to think it is not. I decided to sell it as a custom case. So consider that when bidding. It's a beautiful clock, runs great and looks great. It will be sold as described.It is the best running Atmos I have owned. After some inquiries about the date and further research, the clock likely dates from the second quarter 1942. SN 9623 and has chrome trim.Some questions have come up about locking the pendulum. On the Series two, or least this one, the pendulum lock operates in reverse of how the later clocks work. When the locking lever is to the left, when looking at the front of the clock, the pendulum is locked. When running, the lever is moved to the right.The bellows are good. It is one of the best running Atmos I have the pleasure of owning The name infers that it runs on the atmospheric pressure changes. It in fact runs on temperature changes. It winds with as little as a 2 degree change in temperature. This is accomplished by an ingenious set of bellows, filled with a gas compound that is very volatile at normal room temperature and causes the bellows to expand and contract with a small temperature change. This expansion and contraction though a small chain, pulleys and a ratchet system winds the mainspring, which powers the clock. These are sometimes called perpetual motion clocks, because they do not require winding. It's a misnomer, but effective marketing. This clock was made by Jaegar Le Coultre, a famous swiss firm, who continues to make these clocks today. The serial number of this clock is 9623 For information on the history and rarity of these clocks, see Google. Search atmos clocks.
