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 SET TING
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 (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.
