With the crown in the normal position (0), you can also wind the automatic movement by hand. A few
revolutions of the crown in an anticlockwise direction 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.
