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.
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 “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.

Based on data as of December 2009.
•
The rules governing global times
(UTC offset and GMT differential) and
summer time are determined by each
individual country.
In December 2007, Venezuela
*
changed its offset from –4 to –4.5.
Note, however, that this watch displays
an offset of –4 (the old offset) for the
CCS (Caracas, Venezuela) city code.
