Atmos
®
, the clock that lives on air
Temperature variations are its source of power.
Its balance wheel will oscillate as long as the
sun shines.
Rises in temperature expand the gaseous mix-
ture trapped in the expansion chamber, which
in turn compresses the winding spring. In the
event of a fall in temperature, the reverse oc-
curs. The gas contracts and the spring relax-
es. This imperceptible back-and-forth motion is
sufficient to wind the Atmos® clock.
No battery, no electrical power, no winding.
Accurate and silent.
