Not much was leaked about the Apple Watch Series 9 and Ultra 2 ahead of the company's launch event today, and it might be because most of the changes weren't easily photographed. One of the biggest updates to the company's flagship smartwatches is the S9 SiP (system-in-package), which promises better animations, on-device Siri processing, as well as a whole new gesture called Double Tap. The latter allows you to make a pinch gesture twice in mid-air and use it to do things like answer calls, pause music, dismiss alarms and more.
