ξWith the 24-hour format, times are displayed in the range of 0:00 to 23:59, without any indicator.

ξThe year can be set in the range of 2000 to 2099.

ξThe 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 batteries replaced.

ξThe current time for all city codes in the Timekeeping Mode is calculated in accordance with the UTC time offset of each city, based on your Home City time setting.

World Time

ξThe seconds count of the World Time is synchronized with the seconds count of the Timekeeping Mode.

ξAll World Time Mode times are calculated from the current Home City time in the Timekeeping Mode using UTC time offset values.

ξThe letters “UTC” is the abbreviation for “Coordinated Universal Time”, which is the world-wide scientifi c 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.
