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” on page E-12.
• 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
current digital time and date manually” (page E-40) for more information about manual
time settings.
• 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.
