David Chavez's conceptual braille watch is a simple solution to time-reading for the blind. Instead of tracing the hands on a crystal-less watch face, the visually impaired simply trace the bumps (raised by rotating discs) with their fingers. I actually wouldn't be too averse to owning a watch like this: it would be excellent for covertly checking the time during a terrible movie or a tedious blind date.
