Digital Hour Glass Watch
This is a cool looking idea, the sand + time watch, an egg timer for your wrist.
The watch would function in two ways, the first as a conventional watch displaying the time (hours at the top, minutes at the bottom) but in the more interesting other mode the display will take on the form of an old fashioned egg timer and display the sand falling from the top screen to the bottom.
I do like how the old and new technologies are merged in the sand + time watch, shame it’s just a concept for now.
Concept over at idealist.
