This watch has a screw-in crown. Screwing the crown into its normal position (X) prevents the inad-
vertent 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
11
position 0, the winding 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.
