stop the stopwatch or perform a split time operation.
Checking the Current Time in a Different Time Zone
You can use the World Time Mode to view the current time in one of 29 time
zones around the globe. Each time zone has a “city code”, which is a three-letter
abbreviation of a representative city in the zone. The representative city of the time
zone that is currently selected in the World Time Mode is called the “World Time City”.

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.

to select the city code
for the time whose setting you want to change.
Wait until the
•
n
Right Dial Hands
complete their move
to the time in the currently selected World Time City.
You will not be able to perform step 2 of this procedure
until the hands stop moving.
Hold down
2.
A
for about two seconds until the watch
beeps. This will cause the
v
Left Dial Hand
to toggle
between
DST
(daylight saving time) and
STD
(standard

Note that you cannot switch between
•
STD
(standard
time)/
DST
(daylight saving/summer time) while
UTC
is
selected as the World Time City.
Note that the

STD
(standard time)/
DST
(daylight
saving/summer time) setting affects only the currently
selected time zone. Other time zones are not affected.
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
TYO
(Tokyo) and the World Time
City is
NYC
(New York).
Home City
World Time City
Before swapping
Tokyo
10:08 p.m.
(Standard time)
New York
9:08 a.m.
(Daylight saving time)
After swapping
New York
9:08 a.m.
(Daylight saving time)
Tokyo
10:08 p.m.
(Standard time)
To swap your Home City and World Time City
In the World Time Mode, use
1.
D
to select the World
Time City you want.
In this example, you would move the
•
x
Second Hand
to
NYC
in order to select New York as the World
Time City.
Wait until the
•
n
Right Dial Hands
complete their move
to the time in the currently selected World Time City.
You will not be able to perform step 2 of this procedure
until the hands stop moving.
Hold down
2.
B
for about three seconds until the watch
beeps.
This will make the World Time City (
•
NYC
in this
example) your new Home City. At the same time, it will
change the Home City you had selected prior to step 2
(
TYO
in this example) to your World Time City.
After swapping the Home City and World Time City,
•
the watch will stay in the World Time Mode. The
x
Second Hand
will point to your new World Time City
(
TYO
in this example).
The
•
n
Right Dial Hands
will indicate the current time in
your new World Time City.
Note
If your current World Time City supports time calibration signal reception, making it
•
your Home City enables calibration signal reception for that city.
