In what is likely the most leaked Apple product launch ever, more information gathered from the iOS 11 GM (Golden Master) firmware as well as sources like Verizon, tell us we are going to see a brand new version of the Apple Watch, called Series 3 according to a page on Verizon's website.
Looking very much like its predecessors, the new Apple Watch Series 3 sports a new face, a coloured digital crown and will likely have variants with LTE functionality that's somehow tied in to the user's iPhone SIM card. According to KGI’s Ming-Chi Kuo, the LTE models aren't capable of making or taking calls independently. Non LTE enabled Apple Watch models are expected as well.
