Scrolling
The B and D buttons are used in various modes and setting screens to scroll
through data. In most cases, holding down these buttons during a scroll operation
scrolls through the data at high speed.

Initial Screens
When you enter the 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 day of the week is automatically displayed 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 batteries 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 PM indicator ( 

 ) appears on the bottom dial 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
• Illumination may be hard to see when viewed under direct sunlight.
• Illumination automatically turns off whenever an alarm sounds.
• Frequent use of illumination runs down the batteries.

Auto light switch precautions
• The auto light switch is turned off automatically whenever battery power is at Level

3.

• 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
digital display areas. To avoid running down the batteries, turn off the auto light
switch whenever engaging in activities that might cause frequent illumination.

• Note that wearing the watch under your sleeve while the auto light switch is turned

on can cause frequent illumination of the digital display areas and can run down the
batteries.

• Illumination may not turn on if the face of the watch is

more than 15 degrees above or below parallel. Make
sure that the back of your hand is parallel to the ground.

• Illumination turns off after the preset illumination

duration (see “To set the digital time and date”), 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 you 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.
