Setting the date and the day
20 | 21
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 move-
ment. 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 back-
wards 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.
