Operation Guide 5057
The watch is shipped from the factory with the center dial
hand stopped in order to conserve battery power. Even
though the center dial hand is stopped, the watch
continues to maintain the current time internally. If the
center dial hand is stopped when you purchase the watch,
press any one of the watch's buttons to start hand
movement.

three seconds.
Press A.
Use the Timekeeping Mode to set and view the current
time and date.
• Pressing A in the Timekeeping Mode will cause the
center dial hand to move to the current day of the week.
Press A to return to normal timekeeping. The watch
also will return to normal timekeeping if you do not
perform any operation for about two seconds.
1. In the Timekeeping Mode, hold down A for about three
seconds until the watch beeps.
• The stopwatch second hand and center dial hand will
move to 12 o'clock and stop there. This is the setting
mode.
2. Use D (+) and B (–) to change the time (hour and
minute) setting.

24-hour hand also is at the correct position.
3. After the time setting is the way you want, press C.
• This will cause the watch to beep and change to the
year setting mode.
4. Use D and B to change the year setting.
• You can set the year within the range of 2000 to 2099.
• Use B to move the stopwatch second hand
clockwise to the value of the tens digit that you want
to specify. To set 2012, for example, move the hand to
10.
• Use D to move the center dial hand clockwise to the
value of the units digit that you want to specify. To set
2012, for example, move the hand to 2.
5. After the year setting is the way you want, press C.
• This will cause the watch to beep and change to the
month setting mode.
6. Use D to move the stopwatch second hand clockwise
to the month you want to specify. To set March, for
example, move the hand to 3 (Mar).

• The date will change automatically when the current time reaches midnight. The
date change at the end of a month may take more time than normal.
Stopwatch
You can use the stopwatch to measure elapsed time,

cumulative elapsed time, and lap times. You also can input
(stopwatch minute) hand
the distance of the course or a particular segment of the
Stopwatch second hand
course of the race you are watching. That distance is used
along with the elapsed time, cumulative elapsed time, or
lap time measured by the watch to calculate and display
the average speed for the course or segment.
• See "Average Speed" for more information.
• Never operate the stopwatch while operating a
motor vehicle. Doing so is very dangerous and can
cause an accident.
• Entering the Stopwatch Mode causes the stopwatch

• The display range of the stopwatch is 59 minutes, 59.95 seconds.
• The stopwatch continues to run, restarting from zero after it reaches its limit, until
you stop it.
• You can switch to another mode from the Stopwatch Mode only while the stopwatch
is stopped and reset to all zeros.
To start an elapsed time operation while in the Stopwatch Mode
1. In the Timekeeping Mode, press D to enter the Stopwatch Mode.
2. In the Stopwatch Mode, press B to start elapsed time measurement.
3. Press B to stop elapsed time measurement.
• You can restart and stop elapsed time measurement as many times as you like by
pressing B.
• The center dial hand rotates during the first 60 seconds only, and then stops. When
elapsed time measurement is stopped (by pressing B), the center dial hand jumps
to the 1/20 second indication (which is kept internally).
• Stopping a timing operation will cause the stopwatch second hand to stop at the
elapsed time seconds position. It will remain there if there is no distance value input.
If a distance value is input, the stopwatch second hand will then move to average
speed indication after about two seconds. After that it will move back to the elapsed
time second position.
• After you are finished measuring elapsed time, press D to reset the stopwatch to all
zeros.
• To return to the Timekeeping Mode, press D while the stopwatch is reset to all
zeros.
