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 watchOs 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 watchOs battery replaced or when battery power drops to
Level 5.
" 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.
" The times for the Timekeeping Mode and all the city codes of the World Time Mode
are calculated in accordance with each cityOs UTC differential.
" 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 OUTC� is the abbreviation for OUniversal 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 EarthOs
rotation.
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 PM indicator (PM) 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, without
any indicator.
Illumination Precautions
" Illumination may be hard to see when viewed under direct sunlight.
" Illumination automatically turns off whenever an alarm sounds.
" Frequent use of illumination runs down the battery.
