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 08:00 p.m.
and 02:00 a.m. as the date is automatically advanced by the move-
ment 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.
