Auto Return Features
• If you leave the watch in the Alarm Mode for two or three minutes without performing
any operation, it changes to the Timekeeping Mode automatically.
• If you leave a screen with flashing digits on the display for two or three minutes
without performing any operation, the watch saves any settings you have made up
to that point and exits the setting screen automatically.
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 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.
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 differential values.
• The UTC differential 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 “Universal Time Coordinated”, 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.
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.
• Even if you turn off the button operation tone, the alarm,
Hourly Time Signal, and Countdown Timer Mode alarm
all operate normally.
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 (
not displayed) and off ( displayed).
