Important!
x 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.
x 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
Second Hand.
x If the 2 Second Hand is moving normally at one-second intervals, power is
at Level 1.
x If the 2 Second Hand is moving at two-second intervals, power is at Level 2,
which is quite low (Low battery alert). Expose the watch to light as soon as
possible so it can charge.
Level Hand Movement Function Status
Moves at two-second
intervals.
E-10
1 Normal. All functions enabled
22 Second Hand moves at
2
two-second intervals.
3 All hands stopped at 12 o’clock. All functions disabled
x When power drops to Level 3, all settings (including timekeeping) will be
cleared. Recharging the battery will reset all settings to their initial factory
defaults, so you will need to confi gure settings again.
Time calibration signal reception and
home position adjustment disabled
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.
Charging Guide
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.
x On the dashboard of a car parked in direct sunlight
x Too close to an incandescent lamp
x Under direct sunlight
x When the watch is at Level 3, exposing it to light for a while will cause the 2 Second Hand to move to
the position of second 57. This indicates that charging has started.
Power Recovery Mode
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 continuous signal reception or other operations over a
short period. Note that all operations are disabled while the watch is in the power recovery mode.
The hands will move to the correct positions and the watch will resume normal 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.
Charging Times
Exposure Level (Brightness)
Outdoor sunlight (50,000 lux) 8 minutes 2 hours 18 hours
Window sunlight (10,000 lux) 30 minutes 6 hours 66 hours
Window sunlight on cloudy day (5,000 lux) 48 minutes 8 hours 107 hours
Indoor fl uorescent lighting (500 lux) 8 hours 94 hours – – –
* 1 Approximate exposure each day to generate power for normal daily operation.
* 2 Approximate exposure to take power up one level.
x The above times are for reference only. Actual times depend on lighting conditions.
x For details about the operating time and daily operating conditions, see the “Power Supply” section of
the Specifi cations (page E-49).
Whenever you are not
wearing the watch, be sure
to leave it in a location where
it is exposed to light.
x Best charging
performance is achieved
by exposing the watch to
light that is as strong as
possible.
Daily
Operation *1
When wearing the watch, makes
sure that its face is not blocked
from light by the sleeve of your
clothing.
x The watch may enter a sleep
state (page E-12) if its face is
blocked by your sleeve even
only partially.

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.
x There actually are two sleep state levels: “second hand sleep” and “function sleep”.
Elapsed Time in Dark Operation
60 to 70 minutes (second hand sleep)
6 or 7 days (function sleep)
x The watch will not enter a sleep state between 6:00 AM and 9:59 PM. If the watch is already in a sleep
state when 6:00 AM arrives, however, it will remain in the sleep state.
x The watch will not enter a sleep state while it is in the Stopwatch Mode, or while an elapsed time
operation is in progress in the Timekeeping Mode or the World Time Mode.
To recover from the sleep state
Move the watch to a well-lit area, perform a crown operation, or press any button.

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 “Confi guring Current Time and Date Settings Manually” (page E-32) for more
information.
x Time calibration signal reception is enabled while the watch is in the Timekeeping Mode or World Time
Mode. In this manual, all examples show time calibration signal reception in the Timekeeping Mode.
The same procedures apply while the watch is in the World Time Mode.
x Time calibration reception is based on the applicable mode’s city setting. In the Timekeeping Mode,
the city setting is the Home City. In the World Time Mode, it is the World Time City (page E-28).
This section explains how the watch updates its time settings when the city setting is a city in Japan,
North America, Europe, or China, and is one that supports time calibration signal reception.
If the city setting is this:
LONDON (LON), PARIS (PAR), ATHENS (ATH) Anthorn (England), Mainfl ingen (Germany)
HONG KONG (HKG) Shangqiu City (China)
TOKYO (TYO) Fukushima (Japan), Fukuoka/Saga (Japan)
NEW YORK (NYC), CHICAGO (CHI),
DENVER (DEN), LOS ANGELES (LAX),
ANCHORAGE (ANC), HONOLULU (HNL)
Important!
x The areas covered by HONOLULU (HNL) and ANCHORAGE (ANC) are quite far from the calibration
signal transmitters, so certain conditions may cause reception problems.
x 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.
− Mainfl ingen (Germany) or Anthorn (England) transmitters: 500 kilometers (310 miles)
− Fort Collins (United States) transmitter: 600 miles (1,000 kilometers)
− Fukushima or Fukuoka/Saga (Japan) transmitters: 500 kilometers (310 miles)
− Shangqiu (China) transmitter: 500 kilometers (310 miles)
x As of June 2013, 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 for the
China time zones.
x 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.
The watch can receive the signal from the transmitter
located here:
Fort Collins, Colorado (United States)

Selecting a City
Your watch lets you select from among city codes for 29 cities around the globe, plus one code for
UTC (Universal Coordinated Time). Selecting a city code causes the watch’s time setting to change
automatically to indicate the current time in that zone.
Important!
x You can use the same steps to select a city code in the Timekeeping mode and the World Time Mode.
x In the Timekeeping Mode, the city setting is the Home City, and in the World Time Mode, it is the World
Time City.

STD/DST Switching
You can select summer time or standard time independently for each city. The initial default setting for all
cities is AT (AUTO).
Normally you should use the AT (AUTO) setting because it automatically switches between summer time
and standard time. You should change the setting to STD (standard time) or DST (summer time) in the
following cases.
− When using the watch in a city not included in the City Code Table
− When the switching dates in your location are different from those shown in the City Code Table
Daylight Saving Time (DST)
Daylight Saving Time (summer time) advances the time setting by one hour from Standard Time.
Remember that not all countries or even local areas use Daylight Saving Time.

Troubleshooting
Hand Movement and Position
■ I lost track of what mode the watch is in.
Refer to “Mode Reference Guide” (page E-22). To return directly to the Timekeeping Mode, pull out the crown
to the fi rst click hold down B for at least two seconds. To return to the Timekeeping Mode, push the
crown back in.
■ The
Second Hand is moving at two-second intervals.
Power may be low. Expose the watch to light until the
second intervals (page E-10).
■ 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-12).
x The time setting is being adjusted following a successful auto time calibration signal receive operation
(page E-13).
■ Hands suddenly stop moving. Button operation also is disabled.
The watch may be in the power recovery mode (page E-11). 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.
■ All hands are at 12 o’clock and nothing happens when I press any button.
The rechargeable battery is dead. Expose the watch to light to charge the battery and restore normal
operation.

Time Calibration Signal
The information in this section applies only when LONDON (LON), PARIS (PAR), ATHENS (ATH),
HONOLULU (HNL), ANCHORAGE (ANC), LOS ANGELES (LAX), DENVER (DEN), CHICAGO (CHI),
NEW YORK (NYC), HONG KONG (HKG), or TOKYO (TYO) is selected as the city. You need to adjust
the current time manually when any other city is selected.
■ The
Second Hand indicates N (NO) when I check the result of the latest receive operation.
Possible Cause Remedy Page
x You are wearing or moving the watch, or
performing a button operation during the signal
receive operation.
x The watch is in an area with poor reception
conditions.
You are in an area where signal reception is not
possible for some reason.
The calibration signal is not being transmitted for
some reason.
■ 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 (page E-17), which will
cause the time to be adjusted automatically according to your currently selected city. If this results in the
wrong time setting, check your city setting and correct it, if necessary (page E-28).

■ The current time setting is off by hours.
x Your city setting may be wrong. Check your city setting and correct it, if necessary (page E-28).
■ The current time setting is off by one hour.
x If you are using the watch in an area where time calibration signal reception is possible, see “To select
a city” (page E-28).
x The period when summer time is applied in the location where you are using the watch may be
different from the period set for your currently selected city. Use the procedure under “To switch
between standard time and summer time manually” (page E-31) to switch from AT (AUTO) to STD (for
standard time) or DST (for summer time).
■ 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
(page E-39).
■ Data indication is correct, but it is not in the middle of the day indicator.
The date is in the process of changing. For information about how the date changes, see page E-2.
