1.Enter the Sunrise/Sunset Mode.
•This will display the sunrise and sunset times for the current date (as kept by the Timekeeping Mode) at the location specified by the city code, latitude, longitude, and GMT differential you specified using the procedure under “To specify a city code to check its sunrise and sunset times” and “To configure longitude, latitude and GMT differential settings”.
2.While the sunrise/sunset time are on the display, use D(+) and
•The date (year, month, and day) will appear first, followed by the sunrise and sunset time for that date.
•You can select any date between January 1, 2000 and December 31, 2099.

To record a Time Recorder timeIn the Timekeeping Mode, hold down Bto record the Home City time (month, day, hour, minutes, seconds, and DST on/off setting).
•The recorded time flashes for about two seconds, and then it is assigned a record number. After that, the Timekeeping Mode screen appears.
•Records are assigned numbers sequentially from #01 through #30.

•If you think that the sunrise and/or sunset times are not correct for some reason, check the watch’s city code, longitude, latitude, and GMT defferential settings.
•The sunrise and sunset times displayed by this watch are times at sea level. Sunrise and sunset times are different at altitudes other than sea level.
Sunrise/Sunset Graphic
In the Sunrise/Sunset Mode, the graphic in the upper right corner of the display shows the daylight hours and nighttime hours for the currently selected date. In the Timekeeping Mode, the graphic shows the daylight hours and nighttime hours for today’s date.
•The dark segments of the graphic indicate nighttime hours, while the light segments indicate daytime hours.
•The flashing segment in the graphic in the Timekeeping Mode is the one that represents the current time.
•Each graphic segment represents one hour.

•Storing a new time record when there are already 30 records stored in memory automatically deletes record #01, shifts the remaining records upwards by 1, and stores the new record as #30.
To recall Time Recorder timesIn the Time Recorder Mode, use B(+) and D
•If you recorded a new Time Recorder time since you last entered the Time Recorder Mode, the newest record appears first. If you have not recorded a new time, the record you were viewing when you last exited the Time Recorder Mode appears first.
To delete all Time Recorder timesIn the Time Recorder Mode, hold down A to delete all Time Recorder times.

Bearing ModeWorld Time
Solar azimuth | The Bearing Mode lets you determine approximate | |
directions using a displayed angle value that indicates the | ||
| ||
| angle to the sun (solar azimuth). | |
| • All of the operations in this section are performed in the | |
| Bearing Mode, which you enter by pressing C. |
Important!
Before trying to use this watch to calculate the solar azimuth, make sure to check that the following settings are configured correctly for your current location.
City code and current time settings Longitude, latitude, and GMT differential
City code
Timekeeping
Mode time
Current time in the selected city code
World Time shows the current time in 30 cities (29 time zones) around the world.
•For full information on city codes, see the “City Code Table”.
•The current time for all city codes in the World Time Mode is calculated in accordance with the Greenwich Mean Time (GMT) differential for each city, based on your Home City time setting.
•All of the operations in this section are performed in the World Time Mode, which you enter by pressing C.
The above settings used by this operation are the same as those you configure to calculate sunrise and sunset times. If you have already configured these settings for sunrise/sunset operations, you need only to configure the solar traverse directions here.
•The factory default configuration of the Bearing Mode settings is:
Latitude: North 35 degrees; Longitude: East 140 degrees; GMT Differential: +9
hours; Solar Traverse Direction: South.
•Note that you cannot use the Bearing Mode to determine directions in the following cases.
When the sun is not visible At night
When sun traverses the sky directly overhead or when you cannot determine if it traverses to the north or south
To set the solar traverse directions

by you, along with the watch’s location setup (city code, date, time, longitude, latitude, GMT differential) to calculate and display the solar azimuth.
To determine your bearings1.Enter the Bearing Mode.
•The watch uses the solar traverse directions, along with the watch’s location setup (city code, date, time, longitude, latitude, GMT differential) to calculate and display the current solar azimuth.
2.Find the same value on the bezel as the angle value displayed for the solar azimuth on the Bearing Mode screen.
3.Position the watch so the value you found in step 1 is pointing at the sun.
4.The 12 o’clock position of the watch should now be pointed towards true north.

•Note that the bearings produced by the Bearing Mode are intended for general
reference only.
While in the World Time Mode, press D to scroll through the city codes (time zones) to the east or Bto scroll to the west.
•If the current time shown for a city is wrong, check your Timekeeping Mode time and Home City settings and make the necessary changes.
To toggle a city code time between Standard Time and Daylight Saving Time
|
|
| 1. In the World Time Mode, use B and Dto display the |
|
|
| city code (time zone) whose Standard Time/Daylight |
|
|
| Saving Time setting you want to change. |
|
|
| 2. Hold down A to toggle Daylight Saving Time (DST |
|
|
| indicator displayed) and Standard Time (DST indicator |
|
|
| not displayed). |
|
|
| • The DST indicator is on the display whenever you display |
|
|
| a city code for which Daylight Saving Time is turned on. |
DST indicator |
| • Note that the DST/Standard Time setting affects only the | |
|
|
| currently displayed city code. Other city codes are not |
|
|
| affected. |
•Daylight Saving Time (DST) cannot be turned on and off while GMT is selected as the city code.
•Daylight Saving Time (DST) advances the time setting by one hour from Standard Time. Remember that not all countries or even local areas use Daylight Saving Time.
•The watch will perform a signal receive operation even if it is in the World Time Mode when a calibration time is reached. If this happens, the World Time Mode time settings will be adjusted in accordance with the Home City time.
