It is an RM065 500K Ohm Trimpot Trimmer Potentiometer.  The potentiometer is easy to mount on a PCB and can be adjusted using a screwdriver.

A crystal oscillator is an electronic circuit or device which is used to generate a stable frequency with the help of a crystal instead of a tuned circuit. The crystal when vibrates, it acts like a resonator & as a result generates an oscillated frequency. The resonator circuit uses a crystal to generate the oscillation.
