It's something straight out of Dick Tracy, but now fiction has become a reality and you can talk to friends and family from your wrist using the Apple Watch. Here, we talk you through phone calls on the Apple Watch to give you an idea of what it's like.

Find out more about the Apple Watch in our Apple Watch FAQ, Apple Watch buying guide and Apple Watch review.

How to answer a call on Apple Watch

If someone calls you while you're wearing your Apple Watch (and it's paired to your iPhone), you'll be alerted by a subtle vibration as well as an audible ringtone if you haven't set the device to silent.

Look at your watch and you'll see who's calling, along with an answer or decline button. If it's someone you want to talk to, tap the green answer button. There's a built-in speaker and microphone, so you'll be able to chat without getting your iPhone out of your bag or pocket.

Should you wish to take the phone call on your iPhone (don't forget that everyone else will be able to hear your conversation if you're speaking through your wrist unless you're using a Bluetooth headset), you can seamlessly transfer the call from the Apple Watch to your iPhone by scrolling up using the Digital Crown and tapping 'Answer on iPhone.'

If you are in a busy meeting, for example, you can mute an incoming call simply by covering the Apple Watch with your hand.

How to make a call on Apple Watch

You can also make a call directly from your Apple Watch.

Press the side button to bring up your circle of Friends. You'll see their initials and thumbnail images, which you can tap to call using the aforementioned microphone and speaker.

Tapping on the call button at the bottom left of the screen beneath the person's thumbnail will bring up a list of numbers associated with that person, which you can tap to make the phone call.

You can also use Siri to make a call by saying "Hey Siri" and then "Call Mum," for example.

There is, however, one option that is missing. If your iPhone is in your pocket and you have headphones in, you might think you could tap your watch to answer the call on your phone and speak via the headphones. Sadly, no such feature exists yet.
