stop worrying!!!! your phone/watch might already be state-side and just not scanned yet.
i've done these preorders for years and one year mine didn't get scanned until a couple days before launch/delivery day and it was b/c it was already sitting at the KY UPS distribution center. additionally, when I did the iPhone X launch...my phone (and a bunch of others) went on a tour of Asia due to typhoons (literally went from China to Japan to Korea to Taiwan two days before launch). then when it finally got state-side, there was a flight delay from KY > IAD due to weather on launch day and my phone didn't get to my local UPS distribution center until after they loaded trucks. i guess they held the truck or something but i still got my phone delivered to me on launch day. that was by far one of the most impressive deliveries for launch day i have experienced especially due to the tour of Asia + delays out of KY.
