Germany (Mainflingen), England (Anthorn), the United States (Fort Collins),
China (Shangqiu), and Japan (Fukushima, Fukuoka/Saga).
Current Time Setting

calibration signal. You also can perform a manual procedure to set the time
and date, when necessary.

your Home City (the city where you normally will use the watch). For
more information, see "To specify your Home City" below.
• 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 "Timekeeping" for more information about manual time
• The U.S. 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.
Operation Guide 3147
The electricity generated by the solar cell of the

• When you are not wearing the watch on your
wrist, position the face so it is pointed at a
source of bright light.
