There’s a Kickstarter project that Andrew Plumb (@clothbot) backed and caught my attention. It is a wrist-band watched based on an e-ink display. The battery cell looks like it can provide about a month worth of charge. A very unique looking watch and for an (apparently) limited time, there is a $100 reward level. As Andrew said, it might be worth it to just take the watch apart!
