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 winding position.
By depressing the crown in position X and turning it to the right at the same time, it is
screwed down firmly again and secured.
