Seiko announced their second E-ink watch Thursday. The watch has a new display system that is just as legible as the original, but allows for a much richer range of imagery and data to be displayed on the watch dial. The original watch had a segmented display (much like an ordinary watch). This watch replaced that display with an E-ink screen about an inch across. The new screen has 80,000 pixels, which gives it 300 dpi.
I'm looking forward to when this watch gets hacked. This is a real screen, not your ordinary watch display. There's a near infinite number of ways you can show the time and date.
