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 home position adjustment mode. In either case, any 

adjustments you made before the watch returned to the Timekeeping Mode will be 

applied.

To adjust the home positions

 Hold down 

1. 

C

 for about two seconds until the watch beeps twice and enters the 

Timekeeping Mode.
 Hold down 

2. 

D

 for about three seconds until the watch beeps.

 The watch is now in the home position adjustment 

 

mode.
 The watch will exit the adjustment mode automatically 

 

if you do not perform any o peration 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 

 

C

 in the home position adjustment 

mode will cycle through the adjustment settings as

they both move to 12 o’clock. The 

b

 

Lower Dial 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

 (–) to move them to their proper 

home positions.

 After confirming that the

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.

 Day

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.

World Time Mode

The World Time indicated by the 

n

 

Right 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 

n

 

Right 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.
