Too Long; Didn't Read
By default your watch will come with a bunch of watch faces ready to go. Most likely you won’t ever use a majority of them. The easiest way to customize your faces is through the <a href="https://itunes.apple.com/us/app/watch/id1069511734?mt=8" target="_blank">Watch app</a> on your phone. I recommend you look through the Face Gallery to find the faces that best suit your needs and personality. For me, my main watch face is Numerals because I like the minimal look of it. It’s followed by a Modular watch face which allows for more of my most used complications. I then have an Activity Digital face for exercise, and an Astronomy face because I like space 🚀.
