How useful is Android Wear without Google Apps? I'm thinking about flashing my phone to Cyanogenmod, but I have an Moto 360, so I'm wondering how much of Android Wear is still functioning without Gapps. Does anyone have experiences with this?

I don't really mind things like Google Maps not working properly, but I would like Google Search to work (at at least basic task). I also wouldn't mind installing just the Android Wear app.
When flashing cyanogenmod you can also flash GAPPS. But without it your watch will pretty useless. You won't have maps, hangouts, agenda, Google, Keep, Play Music, Reminders, etc. So I would HIGHLY recommend flashing GAPPS along with CyanogenMod.
