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 better to wind the
watch by turning the crown through approximately 20 revolutions
as this will ensure maximum accuracy.

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 left (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.
