With the crown in the winding position (0), you can also wind the automatic movement by
hand. A few revolutions of the crown are enough to start the movement. However, it is bet-
ter to wind the watch by turning the crown through approximately 20 revolutions as this will
ensure maximum accuracy. The crown must always be in position X when you are wearing
your watch.

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 (direct advance). You should
not use the rapid-advance function between 8 p.m. and 2 a.m. because the movement
automatically advances the date during this period

Pull out the crown to position 2. This will stop the movement. To set the time accurate-
ly 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 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 forwards 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).
