there are very real uses for wearables, especially waterproof ones - kayaking, for example. Keep your phone in your drybox, use your watch to tell your wife how much longer you'll be, or to drop pins on your favorite fishing spot. There are a lot of times i don't want to take my phone out of my pocket or backpack for various reasons, but it'd still be nice to be able to control it easily without having to fiddle with it or press any buttons. Working on the mill in the shop, for example. Or welding. ...or when i'm wrenching on my truck and my phone is inside it, but i'm underneath. The list goes on and on. If they can pull it off well, i can see it being useful.
