Timekeeping
You can adjust the Home Time city date and time in the Timekeeping Mode.
• The analog time of this watch is synchronized with the digital time. The analog time
setting is adjusted automatically whenever you change the digital time.
• If the analog time does not match the digital time for any reason, use the procedure
described under “To adjust home positions” (page E-44) to match the analog setting to
the digital setting.
• Pressing D in the Timekeeping Mode toggles digital display between the Home
City Date and Home City Time.

Stopwatch
You can use the stopwatch to measure elapsed time, lap
times and split times. If you specify a distance value, the
stopwatch also will calculate and display speeds.
• The digital display range of the stopwatch is 99 hours,
59 minutes, 59.999 seconds. The stopwatch continues
to run until you stop it. If it reaches the above limit, it will
restart the time measurement from zero.
• The stopwatch operation continues even if you exit the

a stopwatch operation is in progress, the segments

Each segment represents one second. This is to let you
know that a stopwatch operation is in progress.
• All of the operations in this section are performed in the

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.

Time Measurement
You need to specify either lap time (page E-21) or split time (page E-23) measurement before
you start a stopwatch operation.
• If you want to measure total elapsed time, select split time measurement.

1. In the Stopwatch Mode, make sure the stopwatch is
stopped and reset to all zeros.
• If you need to reset the stopwatch to all zeros, press
A
.
2. Hold down A for about three seconds until the current
distance value setting flashes in the left digital dial.
• This is the distance value setting mode.
3. Press C to move the flashing between the values on
the left side and right side of the distance value decimal
point.
4. While a distance value is flashing, use D (+) and B (–)
to change it.
• You can specify a distance value in the range of 0.1
to 99.9.
5. After specifying the distance value you want, press A
