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 day of the week is automatically displayed in accordance with the date (year,

month, and day) settings.

· 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.

· The current time for all city codes in the Timekeeping Mode and World Time Mode is

calculated in accordance with the Greenwich Mean Time (GMT) differential for each

city, based on your Home City time setting.

· GMT differential is calculated by this watch based on Universal Time Coordinated

(UTC*) data.

* UTC 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 reference point for UTC is Greenwich, England.
