Setting the date
Pull the crown to position B. Set the date by rotating the crown to the

3 AM, as in this period the date is switched automatically by the
movement and damage may be caused to the switching mechanism.
If the month has less than 31 days, the date must be forwarded to the
1st of the following month by hand.
