The app sandboxing in Graphene is the perfect place to use them. All you need is the Galaxy Wear app. Maybe Samsung Health, but I think that is optional.
Along with the protections built into Graphene, I use an always on VPN; and 99% of my accounts use unique email addresses, usernames, and passwords for each account.
App sandboxing is available on standard Android but that means nothing when you log into a Samsung account and give them permissions to all of your personal data.
Well, when they have fake user data and can't access any data from others apps...it means more than nothing.
Do you not have notifications on your smartwatch? No calendar, location, calls, contacts, etc?
