Too much crystal electric power triggers distortion during the oscillator waveform. Furthermore, it causes overheating on the crystal, consequently rendering the resonant frequency unstable. Additional essential would be that the thin plated electrodes can be melted off an overdriven crystal, destroying the gadget.
