Named after former naval officer Bradley Snyder who lost his sight in 2011 while serving as a bomb diffuser in Afghanistan.

Created as a collaboration among engineers, product designers, and people with vision loss, the Bradley watch allows you to feel what time is. The Bradley Element features raised, beveled hour markers that allow you to feel the time by touch: elongated line segments for three, six, nine, and twelve, and shorter line segments for the other markers. Two magnetized ball bearings travel around the watch face in separate, recessed tracks: one track around the center of the watch face’s surface for the minute, and one track around the outside edge of the watch face for the hour. If the bearings move, shake your wrist gently, and they will return to the correct time.
