1. In the Timekeeping Mode, keep A depressed (for
about five seconds) as the second hand moves to the
last signal reception result ("Y" or "N"), then to "READY"
(or "R" for some models), and then to the city code of
the currently selected Home City.

Home City.
LON, PAR, ATH, TYO, ANC, LAX, DEN, CHI, NYC
• The watch will not adjust the DST setting automatically while either of following

• If you want to proceed with adjusting the current time and date setting, continue
from step 3 under "Configuring Time and Date Settings Manually". If you do go the
date and time adjustment procedure, note that you will not be able to return to this
Home City and daylight saving time setting procedure. To return to this procedure,
you will need to press A to exit the time and date setting procedure, and then
perform this procedure from step 1, above.
5. When everything is the way you want, press A.
• This will apply your settings and return to normal timekeeping. The second hand will
move to and start timekeeping from the appropriate seconds count in accordance
with the watch's internal timekeeping.
Configuring Time and Date Settings Manually
You can use the following procedures to adjust the time and date settings when the
watch is unable to receive a time calibration signal for some reason.
1. In the Timekeeping Mode, keep A depressed (for about five seconds) as the
second hand moves to the last signal reception result ("Y" or "N"), then to "READY"
(or "R" for some models), and then to the city code of the currently selected Home

Auto Hand Home Position Correction
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 hand home position
correction corrects the hand position automatically.
• Auto correction is performed in the Timekeeping Mode only. However, auto
correction is never performed while a countdown timer operation is in progress.
• The auto correction operation corrects the positions of the second, minute, and hour
hands. Home position correction of the dial hands and day must be performed
manually, using the procedure under "Manual Home Position Correction".
• Each hour, the watch performs automatic correction of the hand positions from –55
minutes to +5 minutes.
• You also can trigger the auto hand home position correction operation manually, if
you want. See "To trigger the auto hand home position correction operation
manually" for more information.
• The auto hand home position correction operation 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 the auto hand home position correction operation manually" or
"Manual Home Position Correction".
To trigger the auto hand home position correction operation manually
• 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 watch will beep and 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 watch beeps and the second hand stops the first time
(after about three seconds) in the above operation, the watch will enter the manual
home position correction mode, which is described under "Manual Home Position
Correction". If this happens, press A to return to the Timekeeping Mode and then
perform the above operation again.
The manually triggered auto home position correction operation performs the following
two steps.
1. The hands will move automatically in order to determine the home positions of the
watch.
2. After the hand home positions are determined, the watch will return to normal
timekeeping automatically. This completes the correction operation.
Manual Home Position Correction
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. If this happens, perform the
following home position correction procedure.
• Hand home position correction is not required if the time and day settings are
correct.
• You also can use auto hand home position correction to correct the home positions
of the second, minute, and hour hands.
1. In the Timekeeping Mode, hold down D for about three
seconds until the watch beeps and the second hand
stops. Release D at this time.
