hour, it can measure in 1/10 second increments. It will measure in second increments
thereafter. Split time measurement is possible.

measuring, it continues counting. When the split time is being measured, the split
time will be released and counting will continue if the mode is changed.

* For the first one hour, the 24-hour hand moves one marker in 5 minutes. After one hour
has elapsed, it automatically advances to indicate "1" on the 24-hour scale and then
continues to indicate the number of elapsed hours thereafter.
[After the first 10 minutes]
* The 1/10 second hand stays at the "0" position while the stopwatch is counting. When
the measurement is stopped or split time is measured, it indicates the 1/10 seconds
measured. When the measurement is restarted or split time is released, it returns to
the "0" position.
