indicate a speed value, which is calculated based on the
distance you specified and the elapsed time.
The speed value is indicated as described below.
Speed hand: Up to 100
Upper display segments: 100 unit
A 1000 indicator points to 1000 (located to the right of
the upper display segments) when the speed value
exceeds 1000.
• The speed hand indicates speed values less than 100.
Only even-numbered values are indicated.

Time Measurement
You need to specify either lap time or split time measurement before you start a
stopwatch operation.
• If you want to measure total elapsed time, select split time measurement.
To specify lap time or split time readings
1. In the Stopwatch Mode, make sure the stopwatch is stopped and reset to all zeros.

Elapsed Time Measurement
Use the following procedure to measure elapsed time, without taking lap time or split
time readings.
To perform elapsed time measurement
Select split time (

) measurement and then perform the following button operations.
D Start ➝ D Stop ➝ A Reset
• If you have a distance value specified for the current elapsed time measurement, the
upper display segments and speed hand will indicate the speed when you press D
to stop the elapsed time operation.
• After pressing D to stop an elapsed time operation, you could press D again to
restart from the point where you left off.
Lap Time
A lap time reading shows the time elapsed since the last
lap time reading was taken.
• If you want the watch to calculate the speed of each lap
(when all of the laps are the same distance), specify the
lap distance for the distance setting.
• If you want the watch to calculate the speed of the entire
race, specify the race distance for the distance setting.
A speed will be indicated each time you take a lap

reading, but these lap speeds will not indicate actual
speed of the entire race.
To set up the stopwatch to take lap time readings
