With the crown in the winding position (0), you can also wind the
automatic movement by hand. A few revolutions of the crown are

as this will ensure maximum accuracy.

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
screw-in 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 (direct advance). You should not use the rapid-advance
function between 8 p.m. and 2 a.m. because the movement auto-
matically advances the date during this period and the change
mechanism could be damaged.
