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.

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 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 batteries replaced.
World Time
• The World Time Mode times are calculated from the current Home City time setting
in the Timekeeping Mode, using the Greenwich Mean Time (GMT) differentials
associated with each city code.
• The GMT differential is a value that indicates the time difference between Greenwich
Mean Time and the time zone where a city is located.
• GMT differential is calculated by this watch based on Universal Time Coordinated
(UTC) data.
