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 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 Coordinated Universal Time (UTC) for each
city, based on your Home City time setting.
World Time
The seconds count of the World Time is synchronized with the seconds count of the
Timekeeping Mode.
