This watch has a screw-in crown. Screwing the crown in to its
normal position (X) prevents 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 wind-
ing position. By depressing the crown into position X and turning
it to the right at the same time, it is screwed down firmly again
and secured.
