Answer 1

An automatic watch is mechanical not electrical. It gets its power from the movements of the wearer. These movements are used to wind a spring which stores the energy.

The jewels are used in some of the bearings because they wear out much more slowly than a simple metal bearing.

So a "movement" - the name for all the bits and pieces which make the watch work - which uses semi-precious stones (the "jewels") in some of its bearings is called a jewelled movement.

And yes, an automatic movement is different from a quartz movement. Quartz is a mineral and thin slice of it, a quartz crystal, is used in some watches as the timing element, instead of an escapement - look it up in a dictionary or Wikipedia.
A quartz crystal is used as the frequency-determining element in an oscillator and this frequency, which is very stable, is used after it is divided down to 1Hz (one pulse per second) to drive a small motor which in turn drives the hands through gears.

There is quite a bit more to it than this simple description reveals, but you should be able to get the general idea.
