World Time
• The seconds count of the World Time is synchronized with the seconds count of the
Timekeeping Mode.
• All World Time Mode times are calculated from the current Home City Time in the
Timekeeping Mode using UTC time offset values.
• The UTC offset is a value that indicates the time difference between a reference
point in Greenwich, England and the time zone where a city is located.
• The letters “UTC” is the abbreviation for “Coordinated Universal Time”, which is the
world-wide scientific standard of timekeeping. It is based upon carefully maintained
atomic (cesium) clocks that keep time accurately to within microseconds. Leap
seconds are added or subtracted as necessary to keep UTC in sync with the Earth’s
rotation.

Scrolling
The B and D buttons are used in various modes and setting screens to scroll
through data on the display. In most cases, holding down these buttons during a scroll
operation scrolls at high speed.
Initial Screens
When you enter the World Time or Alarm Mode, the data you were viewing when you
last exited the mode appears first.
Timekeeping
••
••
• Resetting the seconds to
00
while the current count is in the range of 30 to 59
causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are
reset to
00
without changing the minutes.
• The year can be set in the range of 2000 to 2099.
• The watch’s built-in full automatic calendar makes allowances for different month
lengths and leap years. Once you set the date, there should be no reason to change
it except after you have the watch’s battery replaced.
E-32
To turn the button operation tone on and off
In any mode (except when a setting screen is on the display), hold down C to toggle
the button operation tone on (the MUTE indicator not displayed) and off (the MUTE
indicator displayed).
• Holding down C to turn the button operation tone on or off also causes the watch’s
current mode to change.
• The MUTE indicator is displayed in all modes when the button operation tone is
turned off.
Auto Return Features
• If you leave the watch in the Alarm Mode for two or three minutes without performing
any operation, it automatically changes to the Timekeeping Mode.
• If you leave a screen with flashing digits on the display for two or three minutes
without performing any operation, the watch automatically exits the setting screen.
E-31
• Map: In the Timekeeping and World Time modes, the map shows the zone where
the currently displayed digital time is from. In the Alarm, Timer, and Stopwatch
modes, it shows the zone of the currently selected Home City Time (T-1).
• Digital dial: In all modes, segments indicate the current Home City Time (T-1) hour,
minute, and second.
Button Operation Tone
The button operation tone sounds any time you press one
of the watch’s buttons. You can turn the button operation
tone on or off as desired.
