Timekeeping

•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.
Calendar
•The year can be set in the range of 2006 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
