    12-hour and 24-hour timekeeping
    With the 12-hour format, the PM indicator appears above the hour digits 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.


    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 in the
    upper right dial will appear and disappear sequentially
    as stopwatch seconds are counted. 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.
    Speed hand
    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
    No speed calculation is performed when 0.0 is specified as the current distance
    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.
