Setting the Time and Date
This watch is preset with UTC differential values that represent each time zone
around the globe. Before setting the time, be sure to set the UTC differential for your
Home Site first, which is the location where you normally will be using the watch.
• Note that World Time Mode times (page E-21) are all displayed based on the time
and date settings you configure in the Timekeeping Mode.
To set the time and date

1. In the Timekeeping Mode, hold down A until the
seconds start to flash, which indicates the setting
screen.
• Be sure to configure the correct UTC differential for
your Home Site before configuring any other
Timekeeping Mode settings.
• See the “UTC Differential/City Code List” at the back
of this manual for information about the UTC
differential settings that are supported.

• The lunitidal interval is the time elapsing between the Moon’s transit over a meridian
and the next high tide at that meridian. See “Lunitidal Interval” (page E-43) for more
information.
• This watch displays lunitidal intervals in terms of hours and minutes.
• The “Site/Lunitidal Interval Data List” at the back of this manual provides UTC
differential and longitude information around the world.
• The following is the initial factory default Home Site data (Tokyo, Japan) when you
first purchase the watch and whenever you have the battery replaced. Change these
settings to match the area where you normally use the watch.
