Starting the clock
Unblock the balance using the blocking lever located at the
front of the clock, under the dial. Lower the lever by pressing
slightly while moving it to the left. Make sure you do not touch
the balance during this operation. Thus released, the balance
begins to oscillate slowly.
If the balance remains motionless :
- Check the level setting.
- Delicately rotate the balance half a turn by hand, then leave
it to resume its own movement by itself.When the balance
is oscillating normally, put the door back in place.
Note : never move an Atmos clock without first blocking
the balance.
Adjusting the gain and loss
Your Atmos Classique clock has been set in the Jaeger-
LeCoultre watchmaking factory located at an altitude of 1000
metres in the heart of the Swiss Jura. If, after about one mon-
th’s operation (one month is still needed to ensure that the
balance is completely stabilised), you observe that it is gaining
or losing time slightly, you can correct this using the adjusting
lever which is located at the top of the movement.
The table below shows you by how many graduations the
adjusting lever must be moved depending on the number of
minutes’ time loss or gain on your clock. In accordance with
the information in the table, to correct for time gain, move the
lever to the left towards the «-» sign; to correct for time loss,
move the lever to the right towards the «+» sign.
Once you have started up your Atmos Classique clock, avoid
touching it. It will operate without any intervention by you,
because the Atmos clock simply lives on air.
