In 2013, CST introduced the CST-01 ultra-thin, flexible E Ink watch. The company later raised over $300,000 in a kickstarter campaign, offering each watch for $129.
Unfortunatly, CST faced production problems, and due to low component yields, and actual price of each watch climbed to $260. CST decided to change its manufacturor (Flextronics), but it is almost out of money.
