 When adjusting a hand or the date home position, it is recommended that after you move to a proper 

 



home position, you press 

B to move the setting back one step. Next, press D again to return it to the 

home position. This helps to ensure better home position adjustment accuracy.

 

 After confi rming that the 

3. 

x Second Hand is at the proper 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. 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 

C. This will switch to b Right Dial Hands home position 

adjustment.

 The 

 



b Right Dial Hands are at their proper home positions if they both move 

to 24. If the hands are not positioned correctly, use 

D (+) and B (–) to move 

them to 24.

 After confi rming that the 

5. 

b Right Dial Hands are in the correct home position, 

press 

C. This will advance to v Left Dial Hand home position adjustment.

 The 

 



v Left Dial Hand is in the correct home position if it is pointing at 12 

o’clock. If it isn’t, use 

D (+) and B (–) to move it to 12 o’clock.

 After confi rming that the 

6. 

v Left Dial Hand is in the correct home position, press 

C. This will advance to day home position adjustment.

 The 

 



n Day is in the correct home position if it shows 1. If it doesn’t, use D (+) 

and 

B (–) to change the day to 1.

 Press 

7. 

A to return to the Timekeeping Mode.

 The 

 



n Day moves to the current day, and then the z Hour Hand and the 

c Minute Hand will move to the current time. Wait until everything stops 
moving.

 

■ 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 

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.

 

■ 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.
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 b Right Dial Hands in the World Time Mode is one hour off from the 

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 b Right Dial Hands in the World Time Mode is off.
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 returns to moving at 

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 receive operation.

 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.

■ The current time setting is off by one hour.

Signal reception on a day for switching between STD 
(standard time)/DST (daylight saving/summer time) may 
have failed for some reason.

Perform the operation under “To get ready for a receive 
operation”. The time setting will be adjusted automatically as 
soon as signal reception is successful.

If you are unable to receive the time calibration signal, 
change the STD (standard time)/DST (daylight saving/
summer time) setting manually.

 

■ Auto Receive is not performed or I cannot perform Manual Receive.

The watch is in the Stopwatch Mode.

Auto Receive is not performed while the watch is in the 
Stopwatch Mode. Hold down 

C for about two seconds to 

enter the Timekeeping Mode.

Your Home City setting is wrong.

Check your Home City setting and correct it, if necessary.

There is not enough power for signal reception.

Expose the watch to light to charge it.

 

■ Signal reception is being performed successfully, but the time and/or day is wrong.

Your Home City setting is wrong.

Check your Home City setting and correct it, if necessary.

The watch may have 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 positions.
