One of the great casio watches!
-24hours countdown set to the second.
-24hours stop watch with digital tachymeter
-3 alarms and an hour chime
-Two tone beeps on changing mode
-And automatic switch to back to time keeping.
A great little mode is the ability to push the right frontal button to have a glimpse on the stop watch.
The stopwatch is spectacular with the three digital eyes showing visual representation of tenth of second, and the seconds and the speed.
The tachymeter goes from 999 km/h to.... Slow.
You can enter the distance of the lap before the calculation.
it was 300$ in 1991
it was a serious attempt for Casio to propose high end watches
the great Chrono!
enjoy as always
