Sony Corp. is developing a watch made out of electronic paper for release as soon as next year in a trial of the company's new venture-style approach to creating products, according to people familiar with the matter.

The watch's face and wrist band will be made from a patented material that allows the entire surface area to function as a display and change its appearance, the people said, asking not to be named because it has not been announced. The device will emphasize style, rather than trying to outdo more technological offerings like Apple Inc.'s watch and Sony's own SmartWatch, they said.

At stake is more than a win against Apple and Samsung Electronics Co. A decade of cost reductions and job cuts has soured Sony's culture of innovation, once celebrated for the Walkman and the Trinitron television. CEO Kazuo Hirai formed a business creation division this year under his direct control to fast-track promising products, and the watch is one of the effort's first results.
