Phosphor has developed digital watches that are not only ergonomic but utilize E Ink in their displays. There are two modes, a standard numeric digital display and a graphic analog hour clock, and you can switch between them depending on your mood. The display autonomously switches between white-on-black to black-on-white time each passing minute. If you like your timepiece busy, the water-resistant watches run $175.00 to $195.00, depending on your choice of style.
