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 displayed automatically 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 power drops to
Level 5.
• The times for the Timekeeping Mode and all the city codes of the World Time Mode
are calculated in accordance with each city’s UTC offset.
• The UTC offset is a value that indicates the time difference between a reference
point in Greenwich, England and the time zone where a city is located.
