This watch is preset with UTC differential values that
represent each time zone around the globe. Before setting
the digital time, be sure to first set the UTC differential for
your Home Time, which is the location where you normally
will be using the watch.

Stopwatches
Your watch has two stopwatch modes: a Single Stopwatch
Mode and a Dual Stopwatch Mode. Both stopwatch
modes measure times in 1/100-second units for the first
hour, and in 1-second units after that. In both stopwatch
modes, timing is possible up to 99 hours, 59 minutes,
59.99 seconds.
The Single Stopwatch Mode (ST1) displays the total
elapsed time and lap times for a single vehicle or runner.
The Dual Stopwatch Mode (ST2) can be used to measure
elapsed time for two vehicles or runners at the same time,
including separate lap times and the time differential
between vehicles or runners.
The data produced by either stopwatch mode is stored
automatically in watch memory, for later recall when you
need it.
• When the elapsed time being kept by either of the stopwatches exceeds 99 hours,
59 minutes, 59.99 seconds, the displayed time returns to all zeros and time
measurement continues from there. Elapsed time measurement continues until you
reset it to all zeros.
• All of the operations in this section are performed in the stopwatch modes, which
you enter by pressing C.
