Reference
This section contains more detailed and technical information about watch operation.
It also contains important precautions and notes about the various features and
functions of this watch.
Auto Return Feature
• If you leave a screen with flashing digits on the display (except Countdown Timer
Mode), for two or three minutes without performing any operation, the watch
automatically exits the setting screen.
• If you leave the watch in the Alarm Mode for two or three minutes without performing
any operation, it returns to the Timekeeping Mode automatically.
Scrolling
C is used in various modes and setting screens to scroll through data on the display.
In most cases, holding down C during a scroll operation scrolls through the data at
high speed.
Initial Screens
When you enter the Timekeeping, Calendar, or Alarm Mode, the data you were
viewing when you last exited the mode appears first.
Timekeeping
• Resetting the seconds to
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
without changing the minutes.
• With the 12-hour format, the PM indicator appears on the display for times in the
range of noon to 11:59 p.m. and AM 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 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is also
applied in Alarm mode.
• The times for all the city codes of the Timekeeping Mode are calculated in
accordance with each city's 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 "UTC" is the abbreviation for "Universal 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 Earth's
rotation.
Calendar
• The year can be set in the range of 2006 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.
