When you're in a meeting or at the movies and a phone call comes in or a loud alert starts dinging, nothing compares to the social awkwardness after realizing you've forgotten to silence your watch. While you can mute the alerts on your Apple Watch with a couple of taps, by the time you fumble through the menus, you'll have already embarrassed yourself.
Thankfully, there's a better way: the Apple Watch includes a nifty little feature for silencing incoming phone calls and other audible alerts with a super quick gesture.
