Google is internally building two Android Wear smartwatches, according to Android Police, and they could be Nexus-branded.
The report says one of the smartwatches will be larger, with a diameter of 43.5mm, and features LTE, GPS, and a heart-rate monitor.

The smaller Android Wear smartwatch will not include LTE nor GPS, and it has a diameter of 42mm. Unlike the larger smartwatch, the smaller one is said to feature interchangeable bands and a more "Apple Watch-like" design.
The new Android Wear smartwatches from Google could be released following the next Nexus handset from a HTC-Google collaboration.
Google uses its Nexus platform to showcase hardware it believes will work best with the latest version of Android. While the Nexus devices are sold to consumers, it's seen as a way for Google to lay a framework for Android device OEMs.
Android Police, citing multiple sources, adds the two smartwatches could feature Google Assistant integration -- the platform Google unveiled at Google I/O 2016 -- as a way of users gaining contextual information through "an ongoing two-way dialogue".
"The assistant is an ambient experience that will work seamlessly across devices and contexts," Google wrote in a blog post following the developer conference in May. "So you can summon Google's help no matter where you are or what the context. It builds on all our years of investment in deeply understanding users' questions."
Google also announced Android Wear 2.0 in May, as the biggest update to Android Wear since its inception. It features a new user interface, standalone apps, enhancements to Google Fit, and more. It's currently in testing with developers and is expected to launch in the fall.
No pricing or release date has been leaked for the smartwatches. Google declined to comment on the rumor.
