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 2039.
•
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.
* The letters ŇUTC” stands for ŇUniversal 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. The reference point for UTC is
Greenwich, England.
12-hour/24-hour Timekeeping  Formats
The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is also
applied in all other modes.
•
With the 12-hour format, the P (PM) indicator appears on the display for times in the
range of noon to 11:59 p.m. and no indicator appears for times in the range of
midnight to 11:59 a.m.
•
With the 24-hour format, times are displayed in the range of 0:00 to 23:59. The
indicator 24 indicates the 24-hour format.
