Setting the time
Pull the winder into position C. That stops the watch movement.
To set your watch accurately to the second, it is best to stop the
movement as the second hand is passing the figure 60. 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 second hand.

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.
