Following the seed of iOS 9.3, Apple has also released the first beta of watchOS 2.2. This update brings only a few updates over the previous version. The main thing that we see is the support of multiple Apple Watches. With iOS 9.3 you can connect more than one Apple Watch to a single iPhone. And with this version of watchOS it’ll support that.
Developers can get this update on their iPhone running iOS 9.3 in the Watch app > General > Software updates > watchOS 2.2.
