Sony mobile announced Tuesday a pair of new Android-based devices: a smartwatch and a smartphone, Computerworld reported.

The SmartWatch 2 will have a 1.6-inch, 220x176-pixel LCD color display and the Xperia Ultra Z will have a 6.44-inch, 1,920x1080-pixel HD display. Both were announced at the Mobile Asia Expo in Shanghai and neither have a set release date or price in the U.S.

SW2 is expected to be available worldwide by September and the Ultra is due out in the third quarter.

When standing on its own, SW2 is a digital watch on which the use can also read previously received notifications.

He also said there are already 200 unique apps for the SmartWatch with one million downloads and counting. He also said he believes, based on analytics, that 41 million smart watches will be sold by 2016.

Apple, Microsoft and Samsung are also reportedly developing a smart watch for release within the next year.

The Xperia Z Ultra will run Android's 4.2 Jelly Bean operating system and will come in purple, as well as black and white. Sony used its Triluminos display technology also used for the company's Bravia HD TV. The display has 16.7 million colors and reproduces missing pixels to optimize an image.
