The stopwatch can carry out measurements for up to 60 minutes in increments of 1/5 of a second.
When the measurement reaches 6 hours, the stopwatch hands are automatically reset to the 0-second position.
When the measurement reaches 60 minutes, the stopwatch second hand automatically stops at the 0-second position.
When starting the stopwatch again and then the buttons are operated to stop the stopwatch or to measure a split time, the stopwatch second hand displays the measured time from the restart.
After the stopwatch is restarted or a split time measurement is released, the stopwatch second hand advances for 60 minutes at the longest.
