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 or when battery level drops to
Level 4.

• 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.

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 without

any indicator.

• The illumination provided by the light may be hard to see when viewed under direct

sunlight.

• Illumination automatically turns off whenever an alarm sounds.

• Frequent use of illumination shortens the battery operating time.
