Apple Watch connects to your iPhone via Bluetooth 4.2 and displays notifications, apps, and more on its 1.5" display. It can also connect directly to the Internet thanks to 802.11b/g/n Wi-Fi. The internal battery lasts for up to 18 hours of normal use and is recharged with an included inductive magnetic charger. Enjoy the iOS apps you love on your iPhone, tailored for Apple Watch. Leave your phone in your pocket and view notifications on your wrist. Apple Watch displays alerts from your iPhone so you can respond or dismiss them at will. Its Taptic engine gives you a gentle tap on your wrist or an audio cue when notifications come in.
Talk to Apple's digital assistant Siri just like you would on your iPhone to launch apps, record notes, search the web, reply to messages, and more. Simply hold down the digital crown or raise your wrist and say "Hey, Siri" to hear her respond. Customize the face of your Apple Watch to fit your needs, from chronographs to digital faces to a model of the solar system. Add the complications of your choice to the watch face so you can see the information most important to you.
