In iOS 10, there’s a new Face Gallery in the Watch app, which is designed to let users customize their Apple Watch faces in watchOS 3 right from their iPhones. Tweaking an Apple Watch face from an awkward angle on a wrist and on a tiny screen can be a hassle, making the Face Gallery a welcome addition to the Watch app.

This is a great idea. Watch the video below to get a sense of how this works.
