As I try to learn just how a quartz watch works, I'm puzzled by the function of the copper cylindrical coil you see in all movements. My first question, then, is just what is its function? I assume it has something to do with taking the electrical energy from the battery and transmitting it to the movement, but I'm very hazy about this. Second, is the coil a component that can affect accuracy--in the sense that a higher-quality coil could be expected to be found in the better HEQ watches? Oh, one last question: Is the tuning-fork quartz crystal found near the coil? Is the crystal encased in a cylindrical enclosure?
Function of the Coil - Any Differences in Quality?
