Forget kinetic, if by kinetic you mean the wrist movements. It's not even remotely possible to use. There are some variations that could work:
Wireless charging stations spreading to shop counters, restaurants, coffee houses stand a better chance.

It's going to take a while. A really long while. Very, very long. Have a look at regular watches, not mechanical, but kinetically charged quartz. How long did that take to develop? 18 years, at Seiko, and not long after, Citizen just overtook the tech with solar charging. Quartz watches are incredibly frugal. Quartz, an amazing achievement that took at least 30 years to develop for the wrist, and to industrialize. Trivialized today, but when it happened it was amazing. For a while there was also tech that used the body's chemistry to charge the batteries, but it wasn't really competitive, not even for frugal quartz watches. What we call smartwatches are in a different league though, microcomputers, with processors, radios, colorscreens... which are just beginning to be able to last a couple of days of battery power. Being small enough to fit on a wrist is an incredible development in and of itself. Kinetic charging from the wrist - run a marathon and your smartwatch, through a kinetic charger, would last perhaps a few seconds, not enough to even boot up. So kinetic, good luck.
