The Stopwatch Mode can indicate elapsed time up to 23 minutes, 59.99 seconds.
D button operation (split, reset) is disabled while hands are moving at high speed
following a reset operation and when transitioning from a split time back to normal
elapsed timekeeping.
Once started, stopwatch timing continues until you press B to stop it, even if you
exit the Stopwatch Mode to another mode and even if timing reaches the stopwatch
limit defi ned above.
The x
Second Hand indicates the 1/10-second count for the fi rst 30 seconds of a
stopwatch elapsed time operation. After that, the hand stops at 12 o’clock.
1/10-second timing continues internally after the fi rst 30 seconds, and the
x
Second Hand will jump to the current value whenever B (Stop) or D (Split) is
pressed.
Though the n
Right Dial Hand is stopped while an elapsed time measurement
operation is in progress, the watch keeps track of the 1/100-second count
internally. The n
Right Dial Hand will jump to the current 1/100-second reading
whenever you 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. The city that is currently selected in the World Time Mode is called
the “World Time City”.
Hand Functions
x Second Hand:
Indicates the currently selected World Time City.
b Lower Left Dial Hands:
Indicate the current time in the selected World Time
City in 24-hour format.
n Right Dial Hand:
Indicates the current STD (standard time) or DST
(daylight saving time) setting of the currently selected
time zone.
To view the time in another time zone
Use 1. C to move the n Right Dial Hand to STD or DST.
The x
Second Hand will move to the city code of the currently selected World
Time City.
Use 2. D to move the x
Second Hand to the city code you want to select as the
World Time City.
The b
Lower Left Dial Hands will move to the current time in the time zone of
the current city code. At this time, the z
Hour Hand and c Minute Hand will
continue to indicate the current time in the Home City.
For full information on city codes, see the “City Code Table”.
If you think that the time indicated for the selected time zone 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” to correct the Home
City settings.

Hold down
A for two
seconds
In the World Time Mode, use 1. D to select the city code
whose setting you want to change.
Wait until the b
Lower Left 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 n Right Dial Hand to toggle
between DST (daylight saving time) and STD (standard
time).
Note that you cannot switch between STD (standard
time)/DST (daylight saving time) while UTC is
selected as the World Time City.
Note that the STD (standard time)/DST (daylight
saving time) setting affects only the currently
selected city code. Other city codes 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 b
Lower Left 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 b
Lower Left 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.

Lower Left Dial Hands one minute.
Holding down D or B will start high-speed hand movement in the applicable
direction. To stop high-speed hand movement, press any button.
