Important!
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 Stopwatch Mode. If you exit the Stopwatch Mode while a stopwatch operation is in progress, the segments along the top of the upper digital display (upper display segments) will indicate the seconds of the current time. 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 Stopwatch Mode, which you enter by pressing C.

•The day of the week is displayed automatically in accordance with the date (year,

•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.
