The Atmos® clock is a very high-precision instru-
ment manufactured with technologies which
only the Jaeger-LeCoultre master-clockmak-
ers are capable of handling. The power need-
ed for this clock to operate is extremely low,
which means that your Atmos® clock must be
placed on a completely stable horizontal sur-
face (chest of drawers, console, etc.) to ensure
optimum operating conditions. Once started,
the clock should not be moved: cleaning the
cabinet or the base should be carried out with-
out handling or moving the clock.
