With the crown in the normal 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. The crown must always be in position 0 when
you are wearing your watch.
