by turning the crown. You must push in the crown to position 0 before wearing the
watch. When setting the time, please be aware of the date change, which always
takes place at 12 midnight. If this change has already taken place at 12 noon, you
must move the hands forwards by 12 hours.

The power reserve display is divided into 7 days with continuous display. The winding

tells you that the power reserve is about to expire. You should then wind the watch by
hand, if necessary, since the precision can be reduced in this area.
