It even lets you customize your watch face to present time in a more meaningful, personal context that’s relevant to your life and schedule. Apple Watch makes all the ways you’re used to communicating more convenient. And because it sits right on your wrist, it can add a physical dimension to alerts and notifications. For example, you’ll feel a gentle tap with each incoming message. Apple Watch also lets you connect with your favorite people.
