A braille watch
A braille watch is a portable timepiece used by the visually impaired to tell time. It is used by touching the dial and noticing the embossments. Both analog and digital versions are available. The analog type differs from the ones used by the sighted in that it lacks the protective glass cover and the clock-hands are constructed to not be susceptible to movement at mere touch of finger that a blind person uses to observe their positions. In other form, the dots (like braille script) keep changing position as time changes. In this case, one must understand the Braille alphabet to make use of such watches. Nowadays, electronic talking watches, which literally tell time at touch of a button, are more popular among blind people.
