Swapping your Home City and World Time City
You can use the procedure below to swap your Home City and World Time City. This capability can come
in handy when you frequently travel between two locations in different time zones.
The following example shows what happens when the Home City and World
Time City are swapped while the Home City originally is
TOKYO
(
TYO
) and
the World Time City is
NEW YORK
(
NYC
).
Home City
World Time City
Before swapping
TOKYO (TYO)
10:08 p.m.
(Standard time)
NEW YORK (NYC)
9:08 a.m.
(Daylight saving time)
After swapping
NEW YORK (NYC)
9:08 a.m.
(Daylight saving time)
TOKYO (TYO)
10:08 p.m.
(Standard time)
To swap your Home City and World Time City
Hold down
A
for about three seconds.
x
This will make the World Time City (
NEW YORK
in this example) your new Home City. At the same
time, it will change your previous Home City to your new World Time City.
x
The
x
x
Second Hand
will point to the new Home City (
NEW YORK
in this example) for about one
second.
Note
x
If your current World Time City supports time calibration signal reception, making it your Home City
enables calibration signal reception for that city.

2. Rotate the crown to move the
x
Second Hand
to the city code you want to select as the World Time
City.
x
Each time you select a city code, the
b
Small Minute Hand
,
n
Small Hour Hand
, and
m
Small Hour
Hand (24-hour)
move to the current time. For details about city codes, see the “City Code Table” at
the back of this manual.
x
Whenever you move the
x
Second Hand
to 12 o’clock while selecting a city code, it will
automatically perform one full revolution and stop at 12 o’clock from the opposite direction.
x
If you think that the time indicated for the selected World Time City is not correct, it probably means
that there is something wrong with your Home City settings. Use the procedure under “To confi gure
Home City settings” (page E-24) to correct the Home City settings.
3. Hold down
A
for about one second to cycle through the summer time settings as shown below.
x
Selecting
AT
(
AUTO
) enables automatic switching between standard time and summer time. For
details about the
AT
(
AUTO
),
STD
and
DST
settings, see “STD/DST Switching” (page E-26).
