I haven't seen this posted anywhere, but handoff actually works between the watch and iPad. Makes sense, since the app is really running on the phone and handoff works between the iPhone and the iPad.
I actually do use my phone less now and it's nice to be able to handoff Siri and other tasks to the bigger screen.
