Setting the Time and Date Manually
Make sure you select your Home Time Zone before you change the current time and
date settings. Dual Time Mode times are all displayed in accordance with the
Timekeeping Mode settings. Because of this, Dual Time Mode times will not be correct
if you do not select the proper Home Time Zone before setting the time and date in the
Timekeeping Mode.
• When setting the time and date, you can also configure settings for your Home Time
Zone (the time zone where you normally use the watch) and summer time (Daylight
Saving time or DST).
To set the time and date manually

differential value starts to flash, which indicates the
setting screen.
• The second hand will move at high speed to the 12
o’clock position, where it will stop.

• Auto DST ( ) can be selected only while –5.0, –6.0, –7.0, –8.0, –9.0, –10.0, +8.0, or
+9.0 ( –4.0, –5.0, –6.0, –7.0, –8.0, –9.0, +9.0, or +10.0 while DST is turned on) is
selected as the Home Time Zone. For more information, see “Daylight Saving Time
(DST)” below.
Daylight Saving Time (DST)
Daylight Saving Time (summer time) advances the time setting by one hour from
Standard Time. Remember that not all countries or even local areas use Daylight
Saving Time.
The time calibration signals include both Standard Time and DST data. When the auto
DST setting is turned on, the watch switches between Standard Time and DST
(summer time) automatically in accordance with the signal it receives.
• The auto DST setting can be turned on only while –5.0, –6.0, –7.0, –8.0, –9.0, –10.0,
+8.0, or +9.0 ( –4.0, –5.0, –6.0, –7.0, –8.0, –9.0, +9.0, or +10.0 while DST is turned
on) is selected as the Home Time Zone.
• If you experience problems receiving the time calibration signal in your area, it is
probably best to switch between Standard Time and Daylight Saving Time (summer
time) manually.
To change the Daylight Saving Time (summer time) setting
1. In the Timekeeping Mode, hold down A until the GMT differential value starts to
flash, which indicates the setting screen.
2. Press C to display the DST setting screen.
3. Press B to cycle through the DST settings in the sequence shown below.
Auto DST ( ) DST off ( ) DST on ( )
4. Press A to exit the setting screen.
• The DST indicator appears on the display to indicate that Daylight Saving Time is
turned on.
• Turning on DST causes the GMT differential value to be increased by one.
