Adjusting the Home Positions
Strong magnetism or impact can cause the hands and/or date of the watch to be off.
If this happens, perform the applicable home position adjustment procedures in this
section.
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.

Troubleshooting

Hand Movement and Position
■ ■ I lost track of what mode the watch is in.
Refer to "To select a mode". To return directly to the Timekeeping Mode from any
other mode, hold down C for about two seconds.
■ ■ The x Second Hand is moving at two-second intervals.
■ ■ All the watch's hands are stopped at 12 o'clock and none of the buttons work.
Power may be low. Expose the watch to light until the x Second Hand starts moving
normally, at one-second intervals.
■ ■ The hands of the watch suddenly start moving at high speed, even when I do
not perform any operation.
This could be due to any one of the following causes. In all cases, the hand movement
does not indicate malfunction, and should stop shortly.
The watch is recovering from a sleep state.
The watch is returning to the Timekeeping Mode automatically from the Alarm
Mode.
■ ■ Hands suddenly stop moving. Button operation also is disabled.
The watch may be in the power recovery mode. Do not perform any operation until the
hands return to their normal positions (in about 15 minutes). The hands should return
to their correct positions when normal operation returns. To help power recover, leave
the watch in a location where it is exposed to light.
■ ■ The current time setting is off by hours.
Your Home City setting may be wrong. Check your Home City setting and correct it,
if necessary.
■ ■ The current time setting is off by one hour.
Use the procedure under "To toggle the Home City time between standard time and
daylight saving time" to change the STD/DST setting.
■ ■ The hands and/or day indications are off.
This could indicate that the watch has been exposed to magnetism or strong impact,
which has caused problems with proper hand and day alignment. Adjust the watch's
hand and day home position alignment.

z Hour Hand and c Minute

n Right Dial Hand is in the
World Time Mode
■ ■ The World Time indicated by the b Lower Left Dial Hands in the World Time
Mode is one hour off from the actual time in the selected time zone.
The STD (standard time)/DST (daylight saving time) setting of the selected World
Time City may be wrong. Select the correct STD (standard time)/DST (daylight saving
time) setting.
■ ■ The World Time indicated by the b Lower Left Dial Hands in the World Time
Mode is off.
Your Home City setting may be wrong. Check your Home City setting and correct it,
if necessary.
Charging
■ ■ The watch does not resume operation after I expose it to light.
This can happen after the power level drops to Level 3. Continue exposing the watch
to light until the x Second Hand starts moving normally (at one-second intervals).
■ ■ The x Second Hand starts moving at one-second intervals, but then suddenly
returns to move at two-second intervals.
The watch probably is not sufficiently charged yet. Continue keeping it exposed to
light.
