Google has re-introduced us to Project Soli, a gesture-recognition tech that's now small enough to fit in a smartwatch. What's that got to do with Apple Watch, you might be wondering? The gestures they've demonstrated today include a call-back to what we mentioned back in May of 2015: that the Apple Watch Digital Crown would be out-done by Google's Project Soli for smartwatches when the time came. That time is now. 

The Apple Watch's Digital Crown allows you to move through screens and lists and you can select items by tapping the device - certainly. It's simple. What Google's new implementation of radar technology in Project Soli does is to move your hand away from the watch - you don't have to touch it at all.
