We first saw E Ink on a watch a few years ago with the Seiko Spectrum now the Phosphor watches uses an E Ink display with many more options and at a much lower price point. The Phosphor watch has two buttons that let you select up to 14 different display options that include going from a black dial to a white one as well as choosing various analog and digital ways of displaying the time. The Phosphor website has a demo that lets you cycle through the options. The watch is available with either a leather or a black polyure thane band and sells for $250.
