😄 That's a terrible design.If Facetime is the only thing that comes to your limited mind, when you read the word camera, then I am happy that you're not a part of Apple's engineering team.
I am talking about a camera either in a band or on the top edge of the watch, that would allow to take pictures and videos without iPhone. This was requested by customers since the introduction of the first Apple Watch. See Wristcam prototype and many others.
