WINDING POSITION
With the crown in the winding position (0), you can also
wind the automatic movement by hand. A few revolutions
of the crown are enough to start the movement. However,
it is recommended to wind the watch by turning the crown
through approximately 20 revolutions as this will ensure
maximum precision.

DATE AND DAY SETTING
If a month has fewer than 31 days, you will need to set the
date manually to the first day of the following month. Release
the screw­in crown and pull it out to position 1. You can now
set the date by turning the crown to the right, and the day by
turning it to the left (rapid adjustment). You should not use
the rapid-adjustment function between 8 p.m. and 2 a.m.
because the movement auto matically advances the date
during this period and the switching mechanism could
be damaged.
