Quartz chronographs L440
Adjusting the time and stop seconds
Unscrew the crown if necessary.
To synchronise the watch with an ofcial time signal (radio, telephone,
etc.), pull the crown to its furthest position 3, at the moment when
the small seconds hand is at 60, then push the crown back in again
to position 1 at the time signal, and screw in.
The calendar changes every time the hour hand passes midnight.
Minute and seconds adjustment
After unscrewing the crown (if necessary) and pulling it to its furthest
position 3, the 3 counter hands will move to the midday position. Turn
the crown to correct the hour and minute hands. Turn the crown
either way to correct the minute. Then push the crown back in again
to position 1, and screw in.
Changing the time zone and the date
Unscrew the crown (if necessary), and pull it out to the intermedi-
ate position 2. The hour hand will make one-hour jumps, enabling
quick time zone adjustments. The hour hand can be moved in either
direction without affecting the minute and seconds hands. Turning
the crown through 24 hours will cause a date change. The crown
be turned either way. Then push the crown back in again to position
1, and screw in.
