A braille watch

A braille watch is a portable timepiece used by the blind or visually impaired to tell time.[1] It is used by touching the dial and noticing the embossments. Both analog and digital versions are available, 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 the digital form, the dots (like braille script) keep changing position as time changes; 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.[2]
