If you’re saving wrist space for the Apple Watch, you might have to free up the other wrist for Nixie. Nixie is the first wearable camera that can fly, and it can be carried around strapped to your wrist just like a watch. When you take it off, it unfolds into a quadcopter with a swiveling camera to take photos or videos of you. After it’s flown around and captured whatever you’re up to, it returns so you can slap it back on your wrist. Basically, it’s a much more convenient option than keeping a drone in your backpack.
