Is it possible with Xamarin Studio create a Watchface project for Android Wear?
Yes it is. Take a look here
Thanks Sebastian, so I think the only way it's create yourself the project, because the support from Xamarin is there.
Yes support is there as well as a project template. Just start Xamarin Studio. Start a new solution and click at the Android app section. There you will find a watch project on the right sight. It is a general watch project not specific to watch faces. But it will get you started.
