Motorola says the watch, called the Moto 360, will be available this summer in "a selection of styles." (The use of 360 is probably a good indication that a round face will at least be one of those options.)
The electronics firm, which Google agreed to sell to Lenovo in January, is one of several companies partnering with Google to bring the Android operating system to wearable devices. LG has also announced its own Android-powered watch, the LG G Watch, and said it will release more details on that device in the "coming months."
Making it easier for developers already well-versed in Android to make apps for wearables, analysts say, is a key development for Google as it looks ahead to its next battle with Apple for app users' loyalty.
Speaking of apps, developers interested in making cool things for the Moto 360 can sign up for more information on the company's Web site. And anyone interested in seeing what Motorola has planned for our increasingly intelligent wrists can sign up to see the Google Hangout reveal today (Wednesday) at 2 p.m., EDT.
