Setting the time
Pull the crown into position C. This stops the movement. You can now
set the required time. To achieve a time display that is as accurate as
possible, we recommend subsequently positioning the minute hand
in a backwards movement. This serves to minimise the degree of tol-
erance in the trains. Example: you wish to set the time as 10.10. Rotate
the minute hand clockwise until 10.20 is displayed, then set the time of
10.10 in anticlockwise direction.
Then move the crown back to position A.

Note for models with second hand: to set the time precisely we
recommend stopping the movement when the second hand is over
the 60.
Setting date and week day (depending on model)
Pull the crown into position B. Twist the crown to the right to set the
date, to the left to set the week day. Date and week day alteration
should not be performed between 8 PM and 2 AM, as in this period
the date and week day are switched automatically by the movement
and damage may be caused to the switching mechanism. If the month
has fewer than 31 days, the date must be forwarded to the 1st of the
following month by hand.
Using the chronoscope
Starting time measurement:
You start the chronoscope by pressing the start-stop button (10).
Stopping time measurement:
You stop the chronoscope by pressing the start-stop button (10) again.
Reset:
Press the reset button (11). This returns all three of the stopwatch
hands to their starting position.
Adding measured times:
After measuring the rst time, you can add times together by pressing
the start-stop button again instead of the reset button. The chrono-
scope hands will then continue running from the stopped position.
