3.1. winding up the watch
with the winder in position a, you can wind up the automatic move-
ment manually. just 2 or 3 turns are sufficient to start the movement
going. it is better to wind it up completely. it is fully wound up after c.
40 rotations of the winder, as then the maximum accuracy and its
power reserve (even after the watch is put down) will last for the maxi-
mum period. if your model has a screw-locked winder, this must be un -
screwed by turning it to the left to start your watch going. after you
have set your watch, you should wear it, so that the automatic wind-
ing system (via rotor movement) keeps it constantly operational.

3.2. setting the time
pull the winder into position c. that stops the watch movement. you can
now position the minute hand precisely in line with the relevant minute
marker and set the desired time. press the winder back into position a
to start the movement.
3.3. setting the date
pull the winder into position b. you can now set the date by turning it
to the right. do not make any changes to the date between 8pm and
2am, as the date is automatically advanced by the movement during
this period and you could damage the date advance mechanism.
if the month has less than 31 days, set the date manually to the first
day of the following month.
3.4. setting the week day (depending on model)
pull the crown into position b. rotate the crown left to set the week day.
do not make any changes to the week day between 8pm and 2am, as
