Often those "higher rate" movements are wasted anyway on a timekeeping device that doesn't have any way to set the time precisely.

Quartz, on a network connected watch, is able to be reliably within tens of milliseconds of the official time which is a level of accuracy you're never going to get on a watch where you manually set the time. It's physically impossible to control your fingers with timing as short as that. There's no way you can press the button within 100 milliseconds of a reference timepiece time unless you spend an hour trying again and again then check how far off you were.

This is a solved problem. I'm all for finding new and interesting ways to solve it... but I don't like the claim that this is a "new chapter" in watchmaking.
