Seiko released the "Spring Drive" movement a few years ago that's interesting as well. Like the Kinetic it's a hybrid electronic / mechanical self-powered movement, but it edges further towards the mechanical, being powered by a traditional mainspring / gear train that's regulated with an electromagnetic brake instead of balance wheel.
