16 | 17 Date setting
If a month has fewer than 31 days, you will need to set the date manually
to the first day of the following month. Release the screw-in crown and pull it
in position 1. You can now set the date by turning the crown to the right (rapid
advance). You should not use the rapid advance function between 8 pm and
2 am because the movement automatically advances the date during this
period and the change mechanism could be damaged.
Time setting
Pull the crown out to position 2. This will stop the movement. To set the time
accurately to the second, it is best to stop the movement as the seconds
hand passes over 60. You can now set the time by turning the crown and
positioning the minute hand exactly above the minute stroke. 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 12 midnight. If this
change has already taken place at 12 noon, you must move the hands for-
ward by 12 hours.
