It is a nice article, but I will be the guy to pick at some nits.
re: Kinetic movements. The keystones of Kinetic is that it uses a normal quartz movement, but the battery (or storage capacitor originally) is recharged by the motion of the rotor. It is not "winding" anything. In this sense it can be thought of more closely related to solar-powered movements, not really mechanical. Personally I do not consider them in the hybrid category at all.
re: Seiko SpringDrive. This is a hybrid that is closer to 85% mechanical automatic. It uses a mainspring that must be wound-up to move the gear-train that moves the hands. The difference is that the rotor also charges up a storage capacitor similar to a Kinetic, and that in turn powers the electronic module that replaces the balance of a purely mechanical movement. So the module applies the braking-force instead of a balance-wheel-and-pawl-system. There is no electric stepper-motor providing the motion, it is a wound-up spring doing that.
I am not sure what you consider to be "advancements in the early 20th century" that led directly to quartz movements. Really it took the invention of digital circuitry more in the middle of the century, then a pulse-counter circuit, a quartz-regulated oscillator, and the stepper-motor. Then it all had to be miniaturized with integrated circuits. Quartz watches at the beginning were technological marvels and were very expensive. Think about how Seiko markets SpringDrive today.
There were stepping-stones to the quartz movement. In the 1950's there were some watches with an electric motor and a battery. They were considered a convenience as you did not have to remember to wind it daily. Not really any more accurate. In the early 1960's Bulova invented the Accutron movement. Accutron was a more accurate electrically-powered movement because it used an electrically-driven vibrating tuning-fork to actually push motion through a gear-train and to the hands. The vibration could be tuned to stay accurate with less than 6 seconds a month of variation. It was this higher-end market that quartz watches were invented to compete in, and eventually dominate.
