(Converts light to
electrical power.)
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. Charging is reduced significantly if the face is even only partially

Radio Controlled Atomic Timekeeping
This watch receives a time calibration signal and updates its time setting accordingly.
This watch is designed to pick up the time calibration signals transmitted in Germany (Mainflingen), •
England (Anthorn), the United States (Fort Collins), China (Shangqiu), and Japan (Fukushima, Fukuoka/
Saga).
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 City (the city
where you normally will use the watch). For more information, see “To specify your Home City”.
When using the watch outside the areas covered by the time signal transmitters, you will have to •
adjust the current time setting manually as required. See “To set the time and date manually” for more
information about manual time settings.
The North American time calibration signal can be picked up by the watch while in North America. The •
term “North America” in this manual refers to the area that consists of Canada, the continental United
States, and Mexico.
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.

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 (five
times for the China signal). When any auto receive is successful, 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 pointing 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.
12 o’clock
or
Make sure the watch is facing the right way.•
Proper signal reception can be difficult or even impossible under the conditions listed below.•
Inside or among
buildings
Signal reception normally is better at night than during the day.•
Time calibration signal reception 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 operations or move the watch during
this time.
The time calibration signal the watch will attempt to pick up depends on its current Home City code •
setting as shown below.
The areas covered by the *HNL, ANC, and MOW city codes are quite far from the time calibration signal
transmitters, and so certain conditions may cause problems with signal reception.
Calibration signal reception is disabled while a countdown timer operation is in progress.•

Note
When a calibration time is reached, the watch will receive the calibration signal only if it is in either the •
Timekeeping Mode or World Time Mode. Reception is not performed if a calibration time is reached
while you are configuring settings.
Auto receive of the calibration signal is designed to be performed early in the morning, while you sleep •
(provided that the Timekeeping Mode time is set correctly). Before going to bed for the night, remove
the watch from your wrist, and put it in a location where it can receive the signal easily.
The watch receives the calibration signal for two to 14 minutes everyday when the time in the •
Timekeeping Mode reaches a calibration time. Do not perform any button operation within 14 minutes
before or after the calibration times. Doing so can interfere with correct calibration.
Remember that reception of the calibration signal depends on the current time in your Home City, as •
kept in the Timekeeping Mode.

Swapping your Home City and World Time City
You can use the procedure below to swap your Home City and World Time City. This changes your Home
City to your World Time City, and your World Time City to your Home City. This capability can come in
handy when you frequently travel between two cities in different time zones.
If your current World Time City supports receipt of a time calibration signal, making it your Home City •
enables calibration signal reception.
For information about which cities support time calibration signal reception, see “To specify your Home •
City”.
To swap your Home City and World Time City
In the World Time Mode, use 1. D to select the World Time City you want.
Hold down 2. A and B until the watch beeps.
This will make the World Time City you selected in step 1 your Home City, and cause the hour and •
minute hands to move to the current time in that city. At the same time, it will change the Home City
you had selected prior to step 2 your World Time City, and cause the content of the upper and lower
displays to change accordingly.
After swapping the Home City and World Time City, the watch stays in the World Time Mode with the •
city that was selected as the Home City prior to step 2 now displayed as the World Time City.
World Time digitally displays the current time in one of 48 cities (29 time zones)
around the world. A simple operation swaps your Home City with the currently
selected World Time City.
The times kept in the World Time Mode are synchronized with the time being •
kept in the Timekeeping Mode. If you feel that there is an error in any World
Time Mode time, check to make sure you have the correct city selected as
your Home City. Also check to make sure that the current time as shown in
the Timekeeping Mode is correct.
Times in the World Time Mode are based on UTC offsets. See the “City •
Code Table” for information about the UTC offsets that are supported.
All of the operations in this section are performed in the World Time Mode, •
which you enter by pressing C.
