Fancy the idea of taking the idea of a progress meter (such as when you're downloading a file) into real space? Check out this design watch from Pierre Haulot. The Elio Linear Scale Watch has two meters instead of hands which track hour and minutes.
Still just as readable as a regular watch, the Linear Scale Watch gives you an overall sense of how much of an hour/day you have left. Great for anal people who plan their day out down to the minutiae.
