Operation Guide 4397/5079
Scrolling
The D and B 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, 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.

UTC Offset/
Code GMT Differential
• Based on data as of June 2008.
• The rules governing global times (GMT differential and UTC offset) 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.
