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 re-
lease the secure crown, unscrew it by rotating it to the left,
where it automatically assumes position 0, the winding
position. By depressing the crown in position X and rota-
ting it to the right at the same time, it is screwed down
firmly again and secured.

Winding position
In the winding position (position 0), you can also wind the
automatic movement by hand. The movement will start
after only a few revolutions of the crown. However, it is
better to wind the movement fully with about 30 revolu-
tions of the crown, as maximum accuracy and a power
reserve of about 42 hours will then be assured, even after
taking off the watch.
Setting the date
If a month has fewer than 31 days, you must set the date
by hand to the first day of the following month. Pull the
crown to position 1. You can now set the date by rotating
the crown to the right (quick setting). You should not per-
form quick setting in the period between 20.00 and 3.00,
since the date is moved forwards automatically by the
movement during this period and the change mechanism
could be damaged.
