Eone Timepieces is launching a Kickstarter campaign to sell a tactile wristwatch for the blind. Selling for $128, the analog timepiece features two metal ball bearings in place of traditional hands — one on the side of the watch, representing the hour, and one on the face, marking the minute.
With no glass covering the face, wearers can tell the time by feeling the position of the bearings, relative to upraised number lines on the face.
The watch’s working mechanism is a magnet that holds the ball bearings in place and prevents the wearer from inadvertently moving them to the wrong position. Full story for BostonGlobe.com subscribers.
