Functions of the crown
X
Normal position
This watch has a screw-in crown. The screw-in connec-
tion (normal position, position X) prevents unintentional
adjustment of the time or the date, and the watch case
has double protection against penetrating water. To
release the secure crown, unscrew it by rotating it to the
left, where it automatically assumes position 0, the wind-
ing position. By depressing the crown in position X and
rotating it to the right at the same time, it is screwed
down firmly again and secured.
