A braille watch is a portable timepiece used by blind or visually impaired people.[1] Braille watch is used by touching the dial and noticing the embossments.The analog versions have a protective glass or crystal cover that is flipped open when time needs to be read and the clock-hands are constructed to not be susceptible to movement at the mere touch of the finger that a blind person uses to observe their positions.In this case, one must understand the Braille alphabet to read the watch.Electronic talking watches, which speak the time at the touch of a button, are also popular among people who are blind.
