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
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
Second Hand will jump to the current value whenever B (Stop) or D (Split) is pressed.
Though the
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
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”.
Hand Functions
x Second Hand: Indicates the currently selected World Time City.
v Left Dial Hand: Indicates the current STD (standard time) or DST (daylight
saving time) setting of the currently selected time zone.
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
Left Dial Hand to STD or DST.
This indicates the World Time Mode.
Use 2. D to move the
Second Hand to the city code you want to select as the
World Time City.
The
Right Dial Hands will move to the current time in the time zone of the
current city code. At this time, the
Hour Hand and
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
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
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
Second Hand to NYC in order to select
New York as the World Time City.
Wait until the
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
Second Hand will point to your new World Time City
(TYO in this example).
The
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.
Using the Alarm
When the alarm is turned on, an alarm will sound for about 10 seconds each day when the time in the
Timekeeping Mode reaches the preset alarm time. This is true even if the watch is not in the Timekeeping
Mode.
Hand Functions
x Second Hand: Indicates the current alarm ON/OFF setting.
v Left Dial Hand: Points to ALM.
b Right Dial Hands: Indicate the current alarm time setting in 24-hour format.
To change the alarm time setting
Use 1. C to move the
Left Dial Hand to ALM.
This indicates the Alarm Mode.
Use 2. D (+) and B (–) to change the alarm time setting.
Each press of either button will move the
Right 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.
The alarm always works based on the time kept in the Timekeeping Mode.
The watch will return to the Timekeeping Mode automatically if you do not perform any operation in the
Alarm Mode for about two or three minutes.
To turn the alarm on or off
In the Alarm Mode, press A to toggle the alarm on and off. The
Second Hand will indicate the current ON/
OFF setting.
To stop the alarm
Press any button.
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
Hour Hand,
Minute Hand, and
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
Second
Hand completes one full revolution.
Though the
Second Hand will stop momentarily about three seconds after
you hold down D, do not release the button yet. Wait until the
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
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
Hour
Hand,
Minute Hand, and
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
Second Hand stops and then
starts moving again.
Hold down 2. D for about three seconds.
The
Second Hand will start to move when you fi rst press D. Keep D
depressed until the
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
Second Hand home position adjustment.
If the
Second Hand moves to 12 o’clock, it is in the correct home position. If
it doesn’t, use D to move it to 12 o’clock.
Each press of
C in the home position adjustment mode will cycle through the
adjustment settings as shown below.
