Few of us think about it — because most of us can see — but nearly every watch on the market requires sight in order to tell the time. Not the Eone Bradley Watch. Named after a former soldier who lost his sight to an IED, this unisex timepiece is designed to be used by everyone — hence the name "Eone". It does so by marking the minutes and hours with two ball bearings, which are set in tracks in the solid titanium body and change positions via hidden magnets inside. The result is a simple, stylish watch that you don't have to watch to use.
