ring as you rotate it.  
After unlocking the crown, grasp the ring and pull the crown out.  
Unlocking the Crown  
Rotate the ring part of the crown towards you until it loosens  
completely.  
Rotating the Crown  
Crown ring  
With the crown pulled out, grasp the ring and rotate the crown  
towards you to move the hands of the watch.  
You can also perform high-speed hand movement using the  
operations described below. Note that there are two levels of high-  
speed movement (High-speed 2 is faster).  
Pressing the Crown Button  
You can press the crown button while the crown is locked.  
x Use High-speed 2 when changing the minute hand setting in the  
Timekeeping Mode, Timer Mode, and Alarm Mode.

Note  
High-speed 1  
x You can use high-speed hand movement when configuring time settings in the  
Timekeeping Mode, Alarm Mode, or Countdown Timer Mode, or when adjusting the  
home positions of the hands.  
With the crown pulled out, rotate it rapidly away from you two times.  
Pushing the Crown In  
Carefully press the button of the crown the push the crown back in.  
High-speed 2  
After starting the High-speed 1 operation, rotate the crown rapidly  
away from you two more times.  
Important!  
High-speed Cancel  
x To prevent unintentional operation, the button press operation of the crown  
becomes disabled automatically for about eight seconds after you push the crown  
back in. It will become re-enabled after about eight seconds.  
Rotate the crown towards you or press any button.  
E-6  
E-7  
Note  
x While crown button mode switching is disabled, pressing the crown button will  
cause the xSecond Hand to move to the 3 o’clock position. The xSecond Hand  
will resume normal timekeeping when you release the crown button.  
x If you do not perform any operation for more than three minutes after pulling out the  
crown, crown operations will become disabled automatically. If this happens, push  
the crown back in and then pull it out again to re-enable crown operations.  
To re-enable crown button mode switching  
Hold down the crown button as you press A.  
Disabling Crown Button Mode Switching  
You can use the following operation to disable crown button mode switching.  
This helps to prevent accidental mode changes while wearing the watch.  
To disable crown button mode switching  
1. Hold down the crown button for at least two seconds until the watch beeps and  
then press A.  
x At this time the xSecond Hand will move to the 3 o’clock position.  
2. Release both buttons.

Power Recovery Mode  
Charging Times  
The watch is designed to go into a power recovery mode that stops hand operation  
temporarily whenever power suddenly drops below a certain level due to overuse  
of the alarm tone over a short period. Note that all operations are disabled while the  
watch is in the power recovery mode.

operation after power recovers (in about 15 minutes). Putting the watch in a location  
where it is exposed to light will help power to recover sooner.

To recover from the sleep state  
Move the watch to a well-lit area, press any button, or perform a crown operation

Power Saving  
Power Saving enters a sleep state automatically whenever the watch is left for a  
certain period in an area where it is dark. The table below shows how watch functions  
are affected by Power Saving.

The vMode Disk uses three different pointers to indicate a variety of different  
information: a mode pointer, a split pointer, and a lap pointer.  
Timekeeping Mode

Mode Pointer  
The mode pointer is in a fixed position. Whenever you enter a mode, the vMode  
Disk will rotate until the current mode indicator (AL, TR, ST, TM, or WT) is aligned  
with the mode pointer. The mode pointer is also used for indication of standard time  
(STD) and summer time (DST).

Split Pointer  
Selecting a Mode  
The split pointer is marked on the vMode Disk. Whenever you enter the Stopwatch  
Split Mode (page E-46), it indicates the current status of the stopwatch operation.  
While a normal stopwatch elapsed time measurement operation is in progress, the  
split pointer will point to RUN. When a split time is indicated by the hands (which are  
temporarily stopped), the split pointer will point to SPL. Stopping the elapsed time  
measurement operation will cause the split pointer to move to STP (stop).  
With this watch, everything starts from the Timekeeping Mode.  
To determine the watch’s current mode  
Check what the mode pointer is indicating on the vMode  
Disk as shown under “To select a mode” (page E-28).

lap time measurement in the Stopwatch Mode, the vMode Disk will rotate so the  
lap pointer points at the current lap number (1 through 5). If the current lap number is

Troubleshooting  
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 xSecond Hand starts moving  
normally, at one-second intervals (page E-18).  
Hand Movement and Position  
I lost track of what mode the watch is in.  
Refer to “To select a mode” (page E-28). To return directly to the Timekeeping Mode  
from any other mode, press and hold the crown button (without unlocking the crown)  
for at least two seconds.  
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.  
x The watch is recovering from a sleep state (page E-23).  
x The watch is returning to the Timekeeping Mode automatically from the Alarm Mode  
(page E-61).  
When pressing the crown button to enter the Stopwatch Split Mode from  
the Timekeeping Mode, the crown needs to be held down longer than when  
switching to another mode.  
The watch is designed this way in order to ensure that the Timekeeping Mode is not  
exited unintentionally due to accidental pressing of the crown button. When entering  
the Stopwatch Split Mode from the Timekeeping Mode, press the crown button and  
hold it down until the mode changes.  
Hands suddenly stop moving. Button operation also is disabled.  
The watch may be in the power recovery mode (page E-20). 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.  
E-76  
E-77  
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 (page E-32).  
Crown Operations  
The watch seems to change modes on its own.  
The watch will change modes whenever you press the button part of the crown. You  
can disable mode switching when the crown button is pressed, if you want.  
See “To disable crown button mode switching” (page E-8).  
The current time setting is off by one hour.  
You may need to change your Home City’s STD (standard time)/DST (daylight saving)  
setting. Use the procedure under “To toggle the Home City time between standard  
time and daylight saving time” (page E-36) to change the STD/DST setting.  
The watch will not change modes.  
Crown button mode switching may be disabled. Re-enable crown button mode  
The hands and/or day indications are off.  
switching.  
See “To re-enable crown button mode switching” (page E-9).  
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 (page E-71).  
Nothing happens when I rotate the crown while it is pulled out.  
You did not perform any operation for more than three minutes while the crown was  
pulled out, causing operation to become disabled automatically. Push the crown in  
and pull it back out again to re-enable operation.

automatically for about eight seconds after you push the crown back in. It will become  
re-enabled after about eight seconds.

Charging  
World Time  
The watch does not resume operation after I expose it to light.  
This can happen after the power level drops to Level 3 (page E-18). Continue  
exposing the watch to light until the xSecond Hand starts moving normally (at one-  
second intervals).  
The indicated World Time is wrong.  
There is a problem with your Home City settings.  
Check your Home City settings.  
See “To configure Home City settings” (page E-32).  
The xSecond Hand starts to move at one-second intervals, but then suddenly  
returns to moving at two-second intervals.  
The watch probably is not sufficiently charged yet. Continue keeping it exposed to  
light.  
The indicated World Time is one hour off.  
The summer time setting for the World Time city is wrong.
