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 recommended
to wind the watch by turning the crown through approximately
20 revolutions as this will ensure maximum precision. 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-adjustment function between 8 p.m. and 2 a.m. because
the movement automatically advances the date during this period.
