Braille watch
A braille watch is a watch (timepiece) where time is displayed in braille. When you touch the dial, you can feel the embossments.
The first braille watches were analog, but today you can buy digital braille watches as well.
Classic analogue braille watches will typically have a protective glass or crystal cover over the display, and you need to flip this cover open to be able to touch the embossments and the clock-hands. The clock-hands are constructed in a way that makes it difficult to accidentally change their position.
Digital braille watches have no clock-hands. Instead, dots (that make up the braille script) will continuously be changing positions. While an analogue braille watch tend to be understandable to anyone, a digital braille watch is only suitable for those how know braille.
Nowadays, braille watches are facing competition from watches that will say what time it is (aloud) at the touch of a button.
