Operation Guide 5083 (OC)
Note
The Stopwatch Mode can indicate elapsed time up to 23 minutes, 59.99 seconds.
In the following cases, the hands of the watch are moving, so pressing
D
or
B
will not perform any
stopwatch operation.
While the hands are moving to elapsed timekeeping after you enter the Stopwatch Mode
−
While the watch is changing dates at midnight
−
Once started, stopwatch timing continues until you press
B
to stop it, even if you exit the Stopwatch Mode
to another mode or timing reaches the stopwatch limit defi ned above.
Whenever you enter the Stopwatch Mode, the hands of the watch move to their initial Stopwatch Mode
positions. If you did not reset the stopwatch the last time you used it, the hands will return to the positions
they were in the last time you exited the Stopwatch Mode.
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
0
. 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
v
Left 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
v
Left 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”.

Left Dial Hand:
Indicates the current
STD
(standard time) or
DST
(daylight
saving time) setting of the currently selected time zone.
b
b
Right Dial Hands:
Indicate the current time in the selected World Time City in
24-hour format.
To view the time in another time zone
Use
1.
C
to move the
v
Left Dial Hand
to
STD
or
DST
.
This indicates the World Time Mode.
Use
2.
D
to move the
x
Second Hand
to the city code you want to select as the
World Time City.
The
b
Right 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.
To specify standard time or daylight saving time (DST) for a city
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
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 time).
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
b
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
b
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.

Auto Correction of Hand Home Positions
Strong magnetism or impact can cause the hands and/or day setting to be off, even if the watch is able
to perform the signal receive operation. Auto correction of hand home positions correct the hand position
automatically.
Auto correction is performed in the Timekeeping Mode only.
Auto correction corrects the positions of the
z
Hour Hand
,
c
Minute Hand
, and
x
Second Hand
. For the
dial hands and day, you must perform the manual adjustment procedure under “Adjusting Home Positions
Manually”.
Each hour, the watch performs automatic correction of the hand positions from –55 minutes to +5 minutes.
You also can trigger auto correction of hand home positions manually, if you want. See “To trigger auto
correction of hand home positions” for more information.
Auto correction of hand home positions can take up to three and a half minutes to complete.
If hand positions are off by one hour or more, correct them using the procedure under “To trigger auto
correction of hand home positions” or “Adjusting Home Positions Manually”.
To trigger auto correction of hand home positions
Perform the following procedure when the time setting is off.
In the Timekeeping Mode, hold down
D
for about six seconds until the
x
Second
Hand
completes one full revolution.
Though the
x
Second Hand
will stop momentarily about three seconds after
you hold down
D
, do not release the button yet. Wait until the
x
Second Hand
completes a full revolution before you release
D
.
To interrupt an ongoing correction operation and return to the Timekeeping
Mode, press
D
again.
If you release
D
when the
x
Second Hand
stops the fi rst time (after about
three seconds) in the above operation, the watch will enter the home position
adjustment mode, which is described under “Adjusting Home Positions
Manually”. If this happens, press
A
to return to the Timekeeping Mode and then
perform the above operation again.
Manually triggered auto correction of hand home positions performs the following
two steps.
The hands will move automatically in order to determine the home positions of
1.
the watch.
After the hand home positions are determined, the watch will return to normal
2.
timekeeping automatically. This completes the correction operation.
Adjusting Home Positions Manually
Strong magnetism or impact can cause the hands and/or date of the watch to be off, even if the watch is able
to perform the signal receive operation. If this happens, perform the applicable home position adjustment
procedures in this section.
Hand home position adjustment is not required if the time and day settings are correct.
You also can use auto correction of the hand home positions to correct the home positions of the
z
Hour
Hand
,
c
Minute Hand
, and
x
Second Hand
.
Note
Any time after you enter the home position adjustment mode in step 1 of the following procedure, you
can return to the Timekeeping Mode by pressing
A
. The watch also will return to the Timekeeping Mode
automatically if you do not perform any operation for about two or three minutes in the home position
adjustment mode. In either case, any adjustments you made before the watch returned to the Timekeeping
Mode will be applied.
To adjust home positions manually
Hold down
1.
C
for about two seconds until the
x
Second Hand
stops and then
starts moving again.
Hold down
2.
D
for about three seconds.
The
x
Second Hand
will start to move when you fi rst press
D
. Keep
D
depressed until the
x
Second Hand
stops.
The watch is now in the home position adjustment mode.
The watch will exit the adjustment mode automatically if you do not perform
any operation for about two or three minutes.
First is
