See “To get ready for a receive operation”.
•To set the time manually
See “Specifying Your Current Location and Setting the Time”.
The watch is now ready for use.
For details about the watch’s radio controlled timekeeping feature, see “Radio•
Controlled Atomic Timekeeping”.
Charging the Watch
The face of the watch is a solar cell that generates power from light. The generated
power charges a built-in rechargeable battery, which powers watch operations. The
watch charges whenever it is exposed to light.
Charging Guide
Whenever you are not
wearing the watch, leave
it in a location where it is
exposed to light.
Best charging•
performance is achieved
by exposing the watch to
light that is as strong as
possible.
When wearing the watch,
make sure that its face is
not blocked from light by the
sleeve of your clothing.
The watch may enter a•
sleep state if its face is
blocked by your sleeve
even only partially.
Warning!
Leaving the watch in bright light for charging can cause it to become quite hot.
Take care when handling the watch to avoid burn injury. The watch can become
particularly hot when exposed to the following conditions for long periods.
On the dashboard of a car parked in direct sunlight•
Too close to an incandescent lamp•
Under direct sunlight•

Important!
Keep the watch in an area normally exposed to bright light when storing it for long•
periods. This helps to ensure that power does not run down.
Storing the watch for long periods in an area where there is no light or wearing it in•
such a way that it is blocked from exposure to light can cause power to run down.
Make sure that the watch is exposed to bright light whenever possible.
Power Levels
You can get an idea of the watch’s power level by
observing the movement of the xSecond Hand in the
regular timekeeping.
If the•xSecond Hand is moving normally at one-second
intervals, power is at Level 1.
If the•xSecond Hand is moving at two-second intervals,
power is at Level 2, which is quite low. Expose the watch
to light as soon as possible so it can charge.

3zHour Hand, xSecond Hand and
cMinute Hand stopped at 12 o’clock. All functions disabled
When power drops to Level 3, all functions will be disabled but the watch will•
continue to keep time internally for about one week. If you recharge the battery
sufficiently during this period, the analog hands will move automatically to the
correct setting and regular timekeeping will resume. After one week, all settings
(including timekeeping) will be cleared. Recharging the battery will reset all settings
to their initial factory defaults.

Power Saving
Power Saving enters a sleep state automatically whenever the watch is left for one
week in an area where it is dark.
What happens when the watch is in the sleep state
All hands move to 12 o’clock and stop.•
Auto Receive becomes disabled.•
Internal timekeeping functions continue to operate normally.•
To recover from the sleep state
Move the watch to a well-lit area or press any button.
It can take as long as 14 minutes for the watch to resume normal operation when•
recovering from the sleep state. Do not perform any watch operation during that
time.
Radio Controlled Atomic Timekeeping
This watch receives a time calibration signal and updates its time setting accordingly.
However, when using the watch outside of areas covered by time calibration signals,
you will have to adjust the settings manually as required. See “Specifying Your
Current Location and Setting the Time” for more information.
This section explains how the watch updates its time settings when the city name
selected as the current location is in Japan or China, and is one that supports time
calibration signal reception.
If your location setting is this: The watch can receive the signal from the
transmitter located here:
HONG KONG (HKG) Shangqiu City (China)
TOKYO (TYO) Fukushima (Japan), Fukuoka/Saga (Japan)

Operation Guide 5095
Even when the watch is within range of a transmitter, signal reception may be•
impossible due to the effects of geographic contours, structures, weather, the time
of year, the time of day, radio interference, etc. The signal becomes weaker at
distances of approximately 500 kilometers, which means that the influence of the
above conditions becomes even greater.
Signal reception may not be possible at the distances noted below during certain•
times of the year or day. Radio interference may also cause problems with
reception.
Fukushima or Fukuoka/Saga (Japan) transmitters: 500 kilometers (310 miles)−
Shangqiu (China) transmitter: 500 kilometers (310 miles)−
As of January 2010, China does not use Daylight Saving Time (DST). If China does•
go to the Daylight Saving Time system in the future, some functions of this watch
may no longer operate correctly.
Using this watch in a country covered by a time calibration signal that is different•
from the countries it supports may result in incorrect time indication due to local
application of summer time, etc.
To get ready for a receive operation
The antenna of this watch is located on its 12 o’clock side. Position the watch with1.
12 o’clock facing towards a window as shown in the nearby illustration. Make sure
there are no metal objects nearby.
Signal reception normally is better•
at night.
The receive operation takes from•
two to seven minutes, but in some
cases it can take as long as
14 minutes. Take care that you do
not perform any button operation or
move the watch during this time.
Signal reception may be difficult or even impossible under the conditions•
described below.

What you should do next depends on whether you are using Auto Receive or2.
Manual Receive.
Auto Receive: Leave the watch over night in the location you selected in step 2.•
See “Auto Receive” for details.
Manual Receive: Perform the operation under “To perform manual receive”.•
Auto Receive
With Auto Receive, the watch performs the receive operation each day•
automatically up to three times between the hours of 2 a.m. and 4 a.m. (1 a.m.
and 3 a.m. for the Chinese calibration signal). When any receive operation is
successful, none of the other receive operations for that day are performed.
When a calibration time is reached, the watch will perform the receive operation•
only if it is in the regular timekeeping. The receive operation is not performed if a
calibration time is reached while you are configuring settings.
To perform manual receive
In the regular timekeeping, keep1. Adepressed (for about two seconds) as the
xSecond Hand goes through the following sequence.
Moves to•YES (Y) or NO (N) to indicate the last signal reception result, then to
Receiving (RC).
The2. xSecond Hand indicates the operations the watch is currently performing.
When the xSecond
Hand is pointed here: It means this:
Receiving (RC) Reception is in progress.
YES (Y) Reception was completed
successfully.
NO (N) Reception failed for some reason.
The receive operation is complete when the3. xSecond
Hand moves to YES (Y) or NO (N) for about five
seconds, and then resumes regular timekeeping.
You can return to the regular timekeeping manually by•
pressing Awhile the xSecond Hand is pointing to
YES (Y) or NO (N).
When the receive operation is successful, the watch•
adjusts the time setting accordingly. It does not adjust
the setting if the operation failed.
Note
To interrupt a receive operation and return to the•
regular timekeeping, press any button.
To check the result of the latest receive operation
In the regular timekeeping, press A.
The•xSecond Hand will move to YES (Y) for five
seconds if the latest receive operation was successful,
or NO (N) if it was not. After that, regular timekeeping
will resume.
You can return to the regular timekeeping manually by•
pressing Awhile the xSecond Hand is pointing to YES
(Y) or NO (N).
Note
The•xSecond Hand will indicate NO (N) if you have
adjusted the time setting manually since the latest
receive operation.

Troubleshooting
Hand Movement and Position
 The xSecond 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 xSecond 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 time setting is being adjusted following a successful auto time calibration•
signal receive operation.
 The current time setting is off by hours.
Your location setting may be wrong. Check your location setting and correct it, if
necessary.
 The hands are off.
This could indicate that the watch has been exposed to magnetism or strong impact,
which has caused problems with proper hand alignment. Adjust the watch’s hand
home position alignment.

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 xSecond Hand starts moving normally
(at one-second intervals).
 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.
Time Calibration Signal
The information in this section applies only when HONG KONG (HKG) or TOKYO
(TYO) is selected as the current location. You need to adjust the current time
manually when OFF is selected as the current location.
 The xSecond Hand indicates NO (N) when I check the result of the latest
receive operation.
Possible Cause Remedy
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 configured for Auto Receive of the time calibration signal
which will cause the time to be adjusted automatically according to your currently
selected location. If this results in the wrong time setting, check your location setting
and correct it, if necessary.
 Auto Receive is not performed or I cannot perform Manual Receive.
Possible Cause Remedy
Your location setting is wrong. Check your location 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 is wrong.
Possible Cause Remedy
Your location setting is wrong. Check your location setting and correct it, if
necessary.
The watch may have been exposed
to magnetism or strong impact, which
has caused problems with proper
hand alignment.
Adjust the watch’s hand home positions.
