Auto Return Features
• The watch automatically returns to the Timekeeping Mode if you do not perform any
button operation for two or three minutes while the Battery Level Screen is
displayed, or while in the Alarm, or Hand Setting Mode.
• If you leave a screen with flashing digits on the display for two or three minutes
without performing any operation, the watch automatically exits the setting screen.

through data on the display. In most cases, holding down these buttons during a scroll
operation scrolls through the data at high speed.
Initial Screens
When you enter the Timekeeping, World Time, or Alarm Mode, the data you were
viewing when you last exited the mode appears first.
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 day of the week is calculated
automatically in accordance with the date.
• 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 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.
Illumination Precautions
• 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.
Auto light switch precautions
• Wearing the watch on the inside of your wrist, movement of your arm, or vibration of
your arm can cause frequent activation of the auto light switch and illumination of the
face of the watch. To avoid running down the battery, turn off the auto light switch
whenever engaging in activities that might cause frequent illumination of the face.
• Note that wearing the watch under your sleeve while the auto light switch is turned
on can cause frequent illumination of the face and can run down the battery.
• Illumination may not turn on if the face of the watch is
More than 15 degrees
more than 15 degrees above or below parallel. Make
too high
sure that the back of your hand is parallel to the ground.
• Illumination turns off after the preset illumination
duration (see "To specify the illumination duration"), even
if you keep the watch pointed towards your face.
• Static electricity or magnetic force can interfere with
proper operation of the auto light switch. If illumination
does not turn on, try moving the watch back to the
starting position (parallel with the ground) and then tilt it
back towards your face again. If this does not work, drop
your arm all the way down so it hangs at your side, and
then bring it back up again.
• Under certain conditions, illumination may not turn on
until about one second after you turn the face of the
watch towards you. This does not necessarily indicate
malfunction of the auto light switch.
• You may notice a very faint clicking sound coming from
the watch when it is shaken back and forth. This sound
is caused by mechanical operation of the auto light
switch, and does not indicate a problem with the watch.
