Movement of the stopwatch 1/20-second
• After the stopwatch is started, the stopwatch 1/20-second disk or
hand moves for about 10 minutes and
automatically stops at the “0” position.
• When the measurement is stopped or split time is measured, the stopwatch 1/20-second disk or hand
moves to indicate the elapsed 1/20 seconds.
• After the stopwatch is restarted or split time is released, the stopwatch 1/20-second disk or hand moves for
about 10 minutes and stops automatically.
• In the same manner, if the stopwatch is stopped and restarted repeatedly or split time is measured and
released repeatedly, the stopwatch 1/20-second disk or hand moves for about 10 minutes and stops
automatically.
* Before using the stopwatch, be sure to check that the crown is set at the normal position and that the
stopwatch disk or hands are reset to the “0” position.
Note: If the stopwatch disk or hands do not return to the “0” position when the stopwatch is reset to “0”, follow the
procedure in "Stopwatch disk or hand position adjustment".
