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 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 0 when you are wearing your watch.
