This watch has a screw­in crown. Screwing the crown in to its normal position (X) pre­
vents the inadvertent adjustment of the time or date and also acts as a double seal to
prevent water from seeping into the case. To release the crown, unscrew it by turning it
to the left, where it automatically assumes position 0, the winding position. By depres­
sing the crown in position X and turning it to the right at the same time, it is screwed
down firmly again and secured.

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.
