Allow your clock to run one week without setting, then regulate as necessary. DON'T move or shift the ATMOS Clock before stopping and locking the balance wheel with the locking lever.DON'T touch the balance wheel or the clock mechanism. I purchased it on e Bay a few weeks ago, and it is the first thing I have actually received from my adventures there.
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.
On 27 July 1935, Jaeger-Le Coultre took over production of Atmos 1 while it developed a second design which used the present ethyl chloride power source.
This model later named the Atmos 2, was announced on 15 January 1936, but problems delayed full production until mid-1939. To date, over 500,000 Atmos clocks have been produced.
The first Atmos clock was designed by Jean-Léon Reutter, an engineer in Neuchâtel, Switzerland, in 1928.
