We always enjoy items that blend the old with the new, and the idea of blending a modern electronic clock with the sand timer, a device that is almost as old as time itself, appealed to us!
You can simply use this as a normal clock, with the usual digital display. However when you switch to the sand timer display, you see a visual representation of a 1 minute sand timer! If you turn the device over, the sand timer starts again. And if you allow the 'sand' to run all the way through, it automatically re-sets, and starts the timer again.
