The next 3 decades saw the development of quartz clocks as precision time standards in laboratory settings; the bulky delicate counting electronics, built with vacuum tubes, limited their use elsewhere. In 1932 a quartz clock was able to measure tiny variations in the rotation rate of the Earth over periods as short as a few weeks. [39]
A crystal oscillator is an electronic oscillator circuit that uses a piezoelectric crystal as a frequency-selective element. [1] [2] [3] The oscillator frequency is often used to keep track of time, as in quartz wristwatches, to provide a stable clock signal for digital integrated circuits, and to stabilize frequencies for radio transmitters and receivers.
A house for sale by its owner. For sale by owner (FSBO) is the process of selling real estate without the representation of a broker or agent.

If I correctly understand the process, quartz crystals are cut to vibrate at a frequency slightly faster than 32,768 Hz, then the crystal is "rated" by comparing its frequency with a standard (e.g. Greenwich time signal or atomic clock), and the regulatory circuitry is adjusted to omit cycles so that the watch or clock keeps exact time.
