This watch designed for the blind is so cool, not only is it up for prestigious design awards, but apparently only a very small percentage of those ordering it are visually impaired. it will be available later this year.
I want one too. the ball bearing round the edge tells the hours. it has no hands to get damaged or gunked up, and does not rely on sound (or light), or the ability to read braille. (Many visually impaired people become so later in life and do not have mad braille skillz)
It's named after a paralympian gold medalist who lost his sight in Afghanistan, and the project originally used crowdfunding to get going.
