The digital hourglass offers the simplicity of an hourglass by starting the count down as soon as it is turned over. Unlike a sand hourglass, the duration of the count down is adjustable between 1 second and 100 minutes. As the timer counts down, "digital sand" flows from the upper to the lower part. This gives a reading at a glance of time remaining. Time elapsed and remaining is also shown. Repeated identical timing operations only require inverting the hourglass, but different times can be easily toggled in. Use as a conventional timer is possible. One button cell battery is included.
