Sony is working on an e-ink smartwatch for a possible release in 2015, Bloomberg reported Wednesday, citing sources familiar with the matter. According to the report, the watch will have both its face and wristband covered with e-ink material, giving it the ability to completely change its appearance. Don’t expect it to be a feature-laden powerhouse, though: The emphasis will be on style, not specs. If it indeed sees the light of day, Sony’s watch will be one of the first results of the company’s new approach to product-building.
