12-hour and 24-hour timekeeping
• With the 12-hour format, the PM indicator appears in the left digital 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
the PM indicator.
• The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is
applied in all other modes.
Important!
• Check to make sure that the speed hand is not moving before you perform any
Stopwatch Mode button operation.
Specifying a Distance Value
You can use the procedure below to specify a distance value, if you want. If you
specify a distance value, the watch will calculate and indicate speed for certain
stopwatch operations.
• The distance value represents kilometers, miles, or any other distance unit you want.
Specifying a distance value of 10.0, for example, can mean 10.0 kilometers or 10.0
miles.
• No speed calculation is performed when 0.0 is specified as the current distance
value.
• For lap time readings, you can specify either the lap distance (when all the laps are
the same distance) or the total race distance.
• For split time readings, you can specify the total race distance only. Though the
watch will indicate a speed each time you take a split reading, they will be based on
the total race distance, and so they will not indicate actual intermediate split speeds.

Swapping your Home City and World Time City
You can use the procedure below to swap your Home City and World Time City. This
changes your Home City to your World Time City, and your World Time City to your
Home City. This capability can come in handy when you frequently travel between two
cities in different time zones.
To swap your Home City and World Time City
1. In the World Time Mode, use D to select the World Time City you want.
2. Hold down A and B until the watch beeps.
• This will make the World Time City you selected in step 1 your Home City, and cause
the hour and minute hands to move to the current time in that city. At the same time,
it will change the Home City you had selected prior to step 2 your World Time City,
and cause the content of left digital dial to change accordingly.
• After swapping the Home City and World Time City, the watch stays in the World
Time Mode with the city that was selected as the Home City prior to step 2 now
displayed as the World Time City.

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 Features
• If you leave the watch with a flashing setting on any display dial for two or three
minutes without performing any operation, the watch will exit the setting mode
automatically.
• The watch will return to the Timekeeping Mode automatically if you do not perform
any operation for two or three minutes in the Alarm Mode.
High-Speed Movement
• The D and B buttons are used to change setting in various setting modes. In most
cases, holding down these buttons will start high-speed movement.
Warning!
••
• Always make sure you are in a safe place whenever you are reading the watch
••
using the auto light switch. Be especially careful when running or engaged in
any other activity that can result in accident or injury. Also take care that
sudden illumination by the auto light switch does not startle or distract others
around you.
••
• When you are wearing the watch, make sure that its auto light switch is turned
••
off before riding a bicycle or operating a motorcycle or any other motor
vehicle. Sudden and unintended operation of the auto light switch can create a
distraction, which can result in a traffic accident and serious personal injury.
To turn the auto light switch on and off
In the Timekeeping Mode, hold down B for about three seconds to toggle the auto
light switch on (auto light switch on indicator displayed) and off (auto light switch on
indicator not displayed).
• The auto light switch on indicator remains in all modes while the auto light switch is
turned on.
• In order to protect against running down the battery, the auto light switch will turn off
automatically approximately six hours after you turn it on. Repeat the above
procedure to turn the auto light switch back on if you want.

When you enter the Stopwatch Mode, World Time Mode or Alarm Mode, the data you
were viewing when you last exited the mode will appear first in the left digital dial.
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 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 when battery has replaced.
• The current time for all city codes in the Timekeeping Mode and World Time Mode is
calculated in accordance with the Coordinated Universal Time (UTC) for each city,
based on your Home City time setting.
3. Check the positions of the hour and minute hands.
• The hands are in the correct home positions if they
are pointed at 12 o’clock. If they aren’t, use D
(clockwise) and B (counterclockwise) to adjust their
positions.

return to regular timekeeping.
• This will cause the hour and minute hands to move to

Illumination Precautions
• Illumination may be difficult to see when viewed under direct sunlight.
• Illumination turns off automatically whenever an alarm sounds.
• Frequent use of illumination runs down the battery.
Auto light switch precautions
• Avoid wearing the watch on the inside of your wrist. Doing so causes the auto light
switch to operate when it is not needed, which shortens battery life. If you want to
wear the watch on the inside of your wrist, turn off the auto light switch feature.
More than 15 degrees
too high

• 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 in about 1.5 seconds or 3 seconds,
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 toward 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.
