IWC Schaffhausen PORTUGIESER YACHT CLUB CHRONOGRAPH Bedienungsanleitung Seite 19

Date setting 16 | 17
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
out to 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 dur-
ing this period.
Time setting
Pull out the crown 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 60. You can now set the time by turning the crown and position-
ing 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-
wards by 12 hours.
Important: Although the watch is water-resistant in positions 0, 1 and 2, the
crown should always be screwed in again for normal use (position X).
