What brand new/emerging technologies did the 1st gen Apple watch use? Apple mostly waits until a technology is proven, if they try something new they usually bury it. See the failure of "AirPower". Or something like "vision pro" mostly all been done before apart from the weird ass screen that shows people's eyes for some reason that everyone hates and will definitely not appear in v2. Apple is a terrible example of innovation for the most part.
