Timekeeping
This watch can keep track of the current time in up to three different time zones.
Home Time
• This is the time in the city where you normally use your watch (Home City). It is the
time displayed in the Timekeeping Mode.
Local Time
• This is the time in the city located in the time zone that is highlighted on the watch’s
world map (Local Time City).
World Time
• This is the time in the city you select in the World Time Mode (page E-47).
E-10
Read This Before You Set the Time and Date!
This watch is preset with a number of city codes, each of which represents the time
zone where that city is located. When setting the time, it is important that you first
select the correct city code for your Home City (the city where you normally use the
watch). If your location is not included in the preset city codes, select the preset city
code that is in the same time zone as your location.
• Note that all of the times for the World Time Mode city codes (page E-48) and Local
Time city codes (page E-18) are displayed in accordance with the time and date
settings you configure in the Timekeeping Mode.
To set your Home City time and date
1. In the Timekeeping Mode, hold down A for about two seconds until the time zone
of the currently selected Home City starts to flash on the world map. This is the
setting screen.
• The Home City code will also appear on the display. Release A immediately
after the Home City code appears. Keeping it depressed longer (about four
seconds) will switch to the Local Time City setting screen, which is indicated
when the Local Time City code is displayed.

Swapping your Home City and Local Time City
You can use the procedure below to swap your Home City and Local Time City. This
capability can come in handy when you travel frequently between two cities in different
time zones.
To swap your Home City and Local Time City
1. In the Timekeeping Mode, select the Local Time City you want.
• For information about selecting a Local Time City, see “To specify the Local Time
City” (page E-18).
2. Hold down B for at least four seconds.
• This will make the Local Time City (which you selected in step 1) your Home City.
At the same time, it will change the Home City you had selected prior to step 2 to
your Local Time City.
Using the Watch when Travelling Between Time Zones
You can use the procedures below for smooth switching between time zones as
required.

Digital Compass/Thermometer
You can take direction readings and temperature readings in the Digital Compass/
Thermometer Mode. Direction readings are taken by the watch’s built-in magnetic
bearing sensor and displayed as one of 16 directions. A temperature sensor is used
for temperature readings.
• See “Digital Compass” on page E-26 for more information about the digital compass.
• See “Thermometer” on page E-41 for more information about the thermometer.

2. Press C to return to the Timekeeping Mode.
• For information about using the digital compass, see “To take a direction
reading” on page E-27.
• For information about using the thermometer, see “To take a temperature
reading” on page E-42.
E-24
Digital Compass
The watch takes digital compass readings automatically whenever you enter the
Digital Compass/Thermometer Mode. In addition, you can take readings manually by
performing the procedure below.
• See “Magnetic North and True North” (page E-39) for information about the two types of
north. For information about maximizing digital compass accuracy, see “Calibrating
the Bearing Sensor” (page E-33) and “Digital Compass Precautions” (page E-39).
E-26
• While the watch is taking compass readings, it
displays a direction angle and a direction indicator,
both of which change dynamically when the watch is
moved. After the compass operation is complete, the
direction pointer disappears from the display, and
the direction angle and direction indicator both show
- - -
“
”. Use the direction indicators marked around
the compass dial to record the indicated direction.
For details, see “Example: Determining your current
position and your objective on a map” (page E-31).
CAL
• The
appearing on the display after a direction
reading is complete indicates that bearing sensor
calibration is required due to either of the reasons
described below. When this happens, perform the
procedure under “Calibrating the Bearing Sensor”
(page E-33).
• It’s been 100 days since the last bearing sensor
calibration.
