Quartz clocks and quartz watches are timepieces that use an electronic oscillator regulated by a quartz crystal to keep time. This crystal oscillator creates a signal with very precise frequency , so that quartz clocks and watches are at least an order of magnitude more accurate than mechanical clocks .
Studies have shown the change in time can affect both physical and mental health

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.
Conservation experts advise clocks need to be serviced regularly. A clock is a complex mechanical contraption made of a variety of materials and with many small moving parts. [10] Even under perfect conditions lubricants deteriorate. Clocks should be examined and re-lubricated every three years.

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.
According to experts at RWJBarnabas Health, a recent study showed that turning the clocks back can seriously affect physical and mental health. According to experts at RWJBarnabas Health, a recent ...
