Sony has secretly been building their own skunk works department in Japan. 200 researchers are trying to flesh out ideas that have nothing to do with the core markets or products that Sony currently is marketing. One of them, to be released next year is a smartwatch, made entirely of e Ink Mobius.
Mobius uses a TFT technology that will enable the watch to be much lighter and rugged . One of the main selling points behind this watch is that it will weigh less than 50% of an equivalent glass based TFT. One of the only consumer products on the market to use this technology was the Sony 13 inch writing Slate, that despite its 13.3 inch display weighs less than a six inch Kindle.
The premise behind the new e Ink watch from Sony is that the screen and band are made entirely of e-paper. This will allow people to not only customize their watch face, which is standard fare int he world of watches, but also the wristband too. Unlike the Pebble, which actually does not use e Ink, the battery life should garner about a month of constant use.
