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.
