DATE CORRECTION
To set the date , unscrew the crown completely
(Aquanaut models), pull it gently to position 2, and
turn it clockwise until the correct date appears in the
aperture. Once you have set the date, push the crown
home again (and screw it down).
NON-USE OF THE WATCH
If you do not intend to use your watch for an extended
period of time, you can disable the movement by gen-
tly pulling the crown out (unscrew first if you have
an Aquanaut model) to position 2 (caliber E 15) or
position 3 (caliber E 23-250 S C). This prevents
unnecessary discharging of the battery.
