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”.

 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 the 

1. 

watch.

 After the hand home positions are determined, the watch will return to normal 

2. 

timekeeping automatically. This completes the correction operation.

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.

 Hold down 

1. 

C at least 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 home adjustment mode 

 

•

automatically if you do not perform any operation for 
about two or three minutes.
 First is 

 

•

x Second Hand home position adjustment.

 If the 

 

•

x 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 

 

•

home position, press 

C. This will switch to z Hour 

Hand and 

c Minute Hand home position adjustment.

 The

z Hour Hand and c Minute Hand are at their 

proper home positions if they both move to 12 o’clock. 
The 

b 24-hour Hand also will move along with 

z Hour Hand movement, and cannot be adjusted 
individually. If the hands are not positioned correctly, 
use 

D (+) and B (–) to move them to their proper 

home positions.

 After confi rming that the 

4. 

z Hour Hand and c Minute 

Hand are in their correct home positions, press

■ 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 at least 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 

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 time setting is being adjusted following a successful auto time calibration signal 

 

•

receive operation.
 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 power recovers. To help power recover, leave the 
watch in a location where it is exposed to light.

■
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.
If you are using the watch in an area where time calibration signal reception is 
possible, see “To confi gure Home City settings”.
If you are using the watch in an area where time calibration signal reception is not 
possible, you may need to change your Home City’s STD (standard time)/DST 
(daylight saving/summer time) setting manually. 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.

 

■ The World Time indicated by the n Right Dial Hands in the World Time Mode is 

The STD (standard time)/DST (daylight saving/summer time) setting of the selected 
World Time City may be wrong. Select the correct STD (standard time)/DST (daylight 
saving/summer time) setting.

 

■ The World Time indicated by the n Right Dial Hands in the World Time Mode 

Your Home City settings may be wrong. Check your Home City settings and correct 
them, if necessary.

 

■ 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 to move at one-second intervals, but then suddenly 

The watch probably is not suffi ciently charged yet. Continue keeping it exposed to 
light.

The information in this section applies only when LON, PAR, ATH, HNL, ANC, LAX, 
DEN, CHI, NYC, HKG, or TYO is selected as the Home City. You need to adjust the 
current time manually when any other city is selected as the Home City.

 

■ The x Second Hand indicates NO (N) when I check the result of the latest 

 You are wearing or moving the watch, 

  

•

or performing a button operation during 
the signal receive operation.
 The watch is in an area with poor 

  

•

reception conditions.

Keep the watch in an area where reception 
conditions are good while the signal receive 
operation is being performed.

You are in an area where signal reception 
is not possible for some reason.

See “Approximate Reception Ranges”.

The calibration signal is not being 
transmitted for some reason.

Check the website of the organization that 

  

•

maintains the time calibration signal in your 
area for information about its down times.
Try again later.

  

•

 

■ The current time setting changes after I set it manually.
You may have the watch confi gured for Auto Receive of the time calibration signal, 
which will cause the time to be adjusted automatically according to your currently 
selected Home City. If this results in the wrong time setting, check your Home City 
setting and correct it, if necessary.
