A positioning system based on satellites. Signals transmitted by GPS satellites include time information
and orbit information. The distances from multiple GPS satellites are used to acquire watch position
information.
xcalibration signal
Long-wave signals emitted by transmitters set up by governments or other organizations that can be used
as timekeeping reference signals. Time calibration signals include time information only.
xtime zone
Global zones that are used to define the standard time at a specific location.
See “UTC (Universal Time Coordinated) and Time Zones” (page L-2) for more information.
xsummer time
A difference of one hour or 30 minutes applied to standard time during summer. The start and end of the
period during which summer time is applied differs according to country and geographic region. Also,
there are countries and/or regions that do not use the summer time system.
xHome City (Time Zone)
The city and/or time zone whose date and time are normally displayed by a timepiece. When GPS
position information is acquired, the current position’s city and/or time zone is the Home City (Time Zone).

(Position Information Acquisition Operation)
When position information is acquired successfully, the watch is able to determine its current location and
adjust its time and date setting accordingly.
Important!
xBefore using the watch, check its current charge level and charge it if necessary. See “Checking the
Charge Level” (page E-17).
xPerform this operation in the Timekeeping Mode (not in the Airplane Mode). See “Mode Reference
Guide” (page E-42).
xIt can take as long as 13 minutes for position information to be acquired.
1. Move to a location that is appropriate for GPS signal reception.
xSee “Appropriate Signal Reception Location (GPS Signal)” (page E-29).
2. Position the watch with its face pointed straight up and acquire position
information.
xHold down Bfor at least three seconds until the
1

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.
xOn the dashboard of a car parked in direct sunlight
xToo close to an incandescent lamp
xUnder direct sunlight
Important!
xKeep 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.
xStoring 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.
E-22
Charging the Watch
The face of the watch is a solar panel 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.
Important!
xThis watch uses a special secondary battery.
−Charging will not be possible if the watch’s temperature is outside the approximate range of
approximately –10°C to 60°C (14°F to 140°F).
−Over-discharge will occur if the watch is not charged within approximately three months after it stops
operation due to low battery power. Charging may not be possible after over-discharge occurs. See
“Power Levels” (page E-24).
Charging Guide
Whenever you are not
wearing the watch, be sure
to leave it in a location where
it is exposed to light.
xBest 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.
xThe watch may enter a sleep
state (page E-27) if its face is
blocked by your sleeve even
only partially.
E-21
Note
xIf the time and/or date setting is not correct even after you try performing the operations below, use
button and crown operations to configure time and date settings manually (page E-63).
−Change to another location and try performing a GPS signal and/or time calibration signal receive
operation again.
−Adjust the hand and day indicator home positions.
xEven in the above case, it is recommended that you move to a location that is appropriate for GPS
signal reception and perform a position information receive operation to configure time and date
settings.
xEven if you are unable to perform a GPS signal and/or time calibration signal receive operation for
some reason, the watch will keep time with average monthly accuracy of ±15 seconds.
E-20
If the time and date settings are incorrect
If the watch’s time and date settings are not correct after you finish performing the procedure above, it
could mean that the watch’s hands and/or date indicator positions are out of alignment. If this happens,
perform the home position adjustment procedure (page E-67).
xNote that an internal decoding process the watch performs after it receives a signal may cause the
time setting to be slightly off (by less than one second). Performing the home position adjustment
procedure does not correct this condition.
If time and date settings still are not correct, try performing the steps below.
Configure the Home City (Time Zone) setting (page E-59) and the summer time setting (page E-60).
Use one of the procedures below.
xPerform the GPS signal time information receive operation to configure time settings (page E-34).
xPerform the time calibration signal auto receive operation to configure time settings (page E-36).
xPerform the GPS signal auto receive operation (page E-32).
Refer to the “City/Time Zone Indicators and Time Offset Table” (page L-3) to select your Home City
(Time Zone).
Important!
xA time calibration signal can be received in specific geographic areas only. See “Time Calibration
Signal Reception Ranges and Conditions” (page E-37).
E-19
Configuring Time and Date Settings
Perform the procedures in this section when the time and date settings of your watch are not correct.

Automatic Timekeeping (by GPS Signal and Time Calibration Signal)
Time and date settings can be configured automatically by performing a GPS signal or time calibration
signal receive operation.
Important!
xBefore trying to receive GPS signal time information and/or a time calibration signal, first use GPS to
acquire GPS position information and configure Home Time (time zone) settings.
See “Acquiring GPS Position Information” (page E-30).
Daily watch operations depend on the geographical area where it is being used.
Areas that Support Time Calibration Signal Reception
A time calibration signal receive operation is performed between midnight and 5:00 a.m., and the time
and date settings are adjusted automatically. If a time calibration signal reception is not possible for some
reason, a GPS signal receive operation is performed between 6:00 a.m. and 10:00 p.m., and the time and
date settings are adjusted automatically.
Areas that Do Not Support Time Calibration Signal Reception
When a GPS signal receive operation is successful between 6:00 a.m. and 10:00 p.m., the time and date
settings are adjusted automatically.
You can also use a button operation to trigger a GPS signal auto receive operation any time during the
day, even if you are in an area where a time calibration signal is not receivable. See “Receiving GPS Time
Information” (page E-34).

Normally you should use the AT (AUTO) setting because it automatically switches between summer time
and standard time. Note, however, that in the cases below you need to change the summer time setting to
DST manually during the applicable summer time period.
−When the dot ( ) mark on the watch’s bezel or dial ring was set manually (when the dot ( ) mark is
set automatically, there is no need to change the setting from AT (AUTO)).
−The actual applicable summer time period is different from the setting summer time period in the
watch.

xThe watch is recovering from a sleep state (page E-27).
xThe time setting is being adjusted following a successful auto signal receive operation (page E-28).
■Hands suddenly stop moving. Button operation also is disabled.
The watch may be in the power recovery mode (page E-25). 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.
