Tim Cook says the Apple Watch provides "new intimate ways to connect and communicate" from your wrist.
The main piece of functionality on Apple Watch comes from the crown. Cook calls it a "digital crown," and it's used to zoom in and out or to scroll. You can press the crown to go back to the home screen.
When you raise your wrist, the display turns on.
The homescreen is a series of dots. Each dot is an app. The watch is touchscreen, so you can swipe.
The Apple Watch also has a magnetic, wireless charger.
Apple has made a variety of different straps in different materials and colors so you can customize your Apple Watch.
The Apple watch comes in two sizes.

The Apple Watch Edition is made from 18 karat gold.
The Apple Watch has customizable information within it, like weather, a calendar, and other widgets.
The Apple Watch has a "taptic engine," a vibration the watch sends to your wrist when you get notifications.
When you get a notification, you raise your wrist to see it and then swipe up to respond. Apple has predictive responses for you too.

You can see all your photos too — just zoom in to see each individually, and swipe through.
There's an Apple Maps app too. You can zoom in with the crown.
Apple Watch's "digital touch" app lets you communicate with friends and talk with little drawings.
