The stopwatch can measure up to 60 minutes in 1/5-second increments (V172, V174, V175) or 1/20-second increments (V176). After measuring 60 minutes, the stopwatch hands will automatically stop at the 0 minute 0 second position.

<Notes on the movement of the stopwatch 1/20 second hand>
After the stopwatch is started, the stopwatch 1/20 second hand moves for about 1 minute and automatically stops at “0” position.
When split time is measured or the measurement is stopped, it moves to indicate the elapsed 1/20 seconds.
After split time is released or the measurement is restarted, it moves for about 1 minute and stops automatically.
In the same manner, if the stopwatch is stopped and restarted repeatedly or split time is measured and released repeatedly, it will keep moving for maximum 2 minutes after the last operation.
Before using the stopwatch
Before using the stopwatch, reset the stopwatch to make sure that the stopwatch hands are reset to the 0 minute 0 second position.
Refer to the following procedure for resetting the stopwatch.
When the seconds hand is moving at two-second intervals, the stopwatch cannot be operated.

How to reset the stopwatch
The stopwatch can be operated when the crown is at the normal position.
