• The watch continues to operate, even when it is not exposed to light. Leaving the
watch in the dark can cause the battery to run down, which will result in some watch
functions to be disabled. If the battery goes dead, you will have to re-configure watch
settings after recharging. To ensure normal watch operation, be sure to keep it
exposed to light as much as possible.

General Guide
• Press C to change from mode to mode.
• About 1.5 seconds after you enter the Dual Time Mode, Alarm Mode, or Hand
Setting Mode the hands will move the position that indicates the current setting of
the mode. You cannot change to another mode while the hands are moving. To
change to another mode, either press C before the hands start to move, or wait
until the hands stop before pressing C.
• In the Timekeeping Mode (except when a setting screen is on the display), press B
to illuminate the face of the watch.
Radio-controlled Atomic Timekeeping
This watch receives a time calibration signal and updates its time setting accordingly.
The time calibration signal includes both Standard Time and Daylight Saving Time
(summer time) data.
• Supported time calibration signals: Germany (Mainflingen), England (Anthorn).
• See the information under "Signal Reception Troubleshooting" if you experience
problems with time calibration signal reception.
Current Time Setting
This watch adjusts its time setting automatically in accordance with a time calibration
signal. You also can perform a manual procedure to set the time and date, when
necessary.
• The first thing you should do after purchasing this watch is to specify your
Home Time Zone, which is the time zone where you normally will use the
watch. For more information, see "To specify your Home Time Zone" below.
• When using the watch outside the range of the time signal transmitter, you have to
adjust the current time setting manually as required. See "Timekeeping" for more
information about manual time settings.

Operation Guide 4719
The electricity generated by the solar cell of the watch is
stored by a built-in battery. Leaving or using the watch
where it is not exposed to light causes the battery to run
down. Make sure the watch is exposed to light as much as
possible.
• When you are not wearing the watch on your wrist,
position the face so it is pointed at a source of bright
light.
• You should try to keep the watch outside of your sleeve
as much as possible. Even if the face of the watch is
blocked only partially from light, charging will be reduced
significantly.

Timekeeping Mode
1. In the Timekeeping Mode, hold down A until the GMT
differential value starts to flash, which indicates the
setting screen.
• The GMT differential value indicates the time
difference in hours between Greenwich Mean Time
and the currently selected time zone.
• The second hand will move at high speed to the 12
o'clock position, where it will stop.
• The DST indicator indicates that Daylight Saving Time
(summer time) is turned on for the currently selected
time zone.
2. Use B (+) to select the time zone you want to use as
your Home Time Zone.
• The following are the GMT differential values for major
cities in the Western Europe time zones.

• The actual level at which some functions are disabled depends on the watch model.
• Be sure to read "Power Supply" for important information you need to know
when exposing the watch to bright light.
If the analog hands aren't moving...
If the analog hands aren't moving, it means that the power saving mode has stopped
them to save battery power.
• See "Power Saving" for more information.
• The hands also stop when the watch's battery runs down.

Press C.
3. Press A to exit the setting screen.
• The second hand will advance at high speed to the correct position and resume
normal movement from there.
• Normally, your watch should show the correct time as soon as you specify your
Home Time Zone. If it does not, it should adjust automatically after the next auto
receive operation (in the middle of the night). You also can perform manual receive
or you can set the time manually.
• Selecting +0.0, +1.0, or +2.0 (+1.0, +2.0, or +3.0 while DST is turned on) as your
Home Time Zone automatically turns on auto receive. When auto receive is turned
on and you are within the reception range, the watch will receive the time calibration
signal from the applicable transmitter automatically (in the middle of the night) and
update its settings accordingly. For information about the relationship between time
zones (GMT differential values) and transmitters, see "Transmitters".
• See the maps under "Approximate Reception Ranges" for information about the
reception ranges of the watch.
• If you are in an area that does not use Daylight Saving Time (summer time), turn off
the DST setting.
• Even if the time calibration signal is received correctly, there are some times when
the analog hands may not indicate the correct time. If this happens, use the
procedures under "Adjusting the Home Positions" to check the home positions of the
hands, and make adjustments as required.
Time Calibration Signal Reception
There are two different methods you can use to receive the time calibration signal:
auto receive and manual receive.
• Auto Receive
With auto receive, the watch receives the time calibration signal automatically up to six
times a day. When any auto receive is successful, the remaining auto receive
operations are not performed. For more information, see "About Auto Receive".
• Manual Receive
Manual receive lets you start a time calibration receive operation with the press of a
button. For more information, see "To perform manual receive".
Important!
• When getting ready to receive the time calibration signal, position the watch as
shown in the nearby illustration, with its 12 o'clock side facing towards a window.
This watch is designed to receive a time calibration signal late at night. Because of
this, you should place the watch near a window as shown in the illustration when you
take it off at night. Make sure there are no metal objects nearby.
• Button operations are indicated using the letters shown
in the illustration.
• Each section of this manual provides you with the
Minute hand
information you need to perform operations in each
mode. Further details and technical information can be
found in the "Reference" section.
