It is a time difference adjustment function to show the times of two
areas where there is a time difference in between, such as London
and Tokyo. The 24-hour hand, which takes 24hours to turn full cir-
cle on the watch, shows the time of a different time zone. Please
note that there are two different ways of using the 24-hour hand.
Choose the way of using it before setting the time.
This watch, Cal.9S56, features a time
difference adjustment function.
Two different time zones can be displayed
at the same time when you set
the hour hand and 24-hour hand respectively
in accordance with each time zone.

The 24-hour hand shows
what time of AM/PM it is now.
Set the 24-hour hand to the current time of the
place you are staying to use it as a 24-hour
display. Only by seeing the direction that the
24-hour hand shows, you can see what time
it is and whether it is AM or PM. If you set
the 24-hour hand to Japan standard time, you
can check Japan time even when you set the
hour hand and the second hand to the local
time while you are abroad. This is very conve-
nient.

One watch, two time zones
You can see the times of
two different areas on your watch
Set the 24-hour hand to the time of an area in
different time zone from your residence. The
24-hour hand and the hour hand show two
different time zones respectively. For instance,
if you set the 24-hour hand to Greenwich
Mean Time and set the hour hand to Japan
standard time, you can always check GMT
while you are seeing the current time in
Japan.

Set the time
without stopping the watch.
It seems that many people do not like setting
the watch to local time when they are
abroad. Pull out the crown, stop the watch
once, set the time by turning the watch hand,
and make the second hand start according to
the time signal…these efforts are no longer
necessary if you use the time difference
adjustment function. Set the hour hand only to
local time per hour, without stopping the
minute hand and the second hand. Since the
date changes according to the hour hand, the
right date of the place you are staying can be
also displayed.
