Sony has started teasing a new smartwatch ahead of the 2013 Mobile Asia Expo scheduled to take place in Shanghai from June 26th to the 28th. The Japanese manufacturer repeatedly tweeted “it’s time” in reference to MAE13 and claimed “one in three smartphone users want smart wrist wear” on Twitter. Sony also proudly boasted that wearable tech is in the company’s DNA, pointing to the classic Walkman as proof. We already know Sony will soon unveil the Xperia Z Ultra, a behemoth of an Android smartphone with a 1080p 6.4-inch display and powered by a Snapdragon 800 processor. Now, it seems Sony will be announcing a sequel to its SmartWatch as well.
