mountains. If, after about one month’s opera-
tion (one month is still needed to ensure that
the balance wheel 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 grad-
uations the adjusting lever must be moved de-

gain on your clock. In accordance with the in-
formation 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.
