Sony has developed a watch made from e-paper as part of an initiative to experiment with the use of the material for fashion products. One of the predictions for next year is that fashion is going to play a huge part in shaping the tech industry. The watch face and straps have an e-paper display - comparable to the technology used in e-book readers such as Amazon's Kindle.It means the watch can alternate between several different styles of watch face and strap design & has a battery life of 60 days. Other e-paper experiments being worked on by Fashion Entertainments include shoes, bow-ties and glasses.
