Setting the date and the day
18 | 19
If a month has fewer than 31 days, you must set the date by hand to the first
day of the following month. Release the screw-in crown and pull it out to
position 1.You can now set the date by rotating it to the right, and the day
by rotating it to the left (quick setting). You must not perform quick setting
between 20.00 and 2.00, since the date is changed automatically by the
movement during this time period and the change mechanism could be
damaged.
Setting the time
Pull out the crown to position 2. This will stop the movement. For setting
the time accurately to the second, it is best to bring the movement to a stop
as the seconds hand passes over 60. You should now move the minute
hand a few minute lines beyond the time to be set. Then position the minute
hand by moving it gently backwards until it is exactly above the correct
minute line. By adopting this procedure, you will ensure that the minute hand
begins to move without any delay when you restart the movement. To start
the seconds hand, push in the crown to position 0. When setting the time,
please be aware of the date change, which always takes place at midnight
(24.00). If this change has already taken place at 12.00 noon, you must turn
the hands forwards through 12 hours.
