This watch has a screw-in crown. Screwing the crown into its normal position (X) prevents the inad-
vertent adjustment of the time or perpetual calendar 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 automat-
4
ically assumes 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.
