My automatic watch contains an electronic circuit, so I'm not sure what your point is.

Interesting. What is the circuit for ?

Are you sure it's not powered by a standard watch battery ?

Yes, it is a quartz movement with a capacitor that is charged by a mechanism similar to a mechanical auto-winding watch.
