Quartz crystals, when properly sized, oscillate (vibrate) at fixed frequencies. These frequencies are not affected by temperature variations, other vibrations, radio waves, etc.
A small quartz crystal will oscillate at 32,768 hertz (cycles per second) given a low amount of power (like that of a watch battery).
Since the number 32,768 is a power of 2, and can easily be counted by a digital counter, the quartz crystal oscillator is a perfect match for use in a digital watch. Simply put, each time the crystal oscillates, the circuitry in the watch increments a 15-bit binary digital counter. Once the counter resets to 0, one second has passed.

What clock came after pendulum clock?
The pendulum clock was followed by the quartz clock. Quartz clocks use the vibrations of a quartz crystal to keep time, and are more accurate and reliable than pendulum clocks. They have largely replaced pendulum clocks in modern timekeeping.
When were pendulum clocks replaced by more accurate clocks?
Pendulum clocks were largely replaced by more accurate clocks, such as quartz clocks and atomic clocks, in the late 20th century. Quartz clocks were first developed in the 1920s and became popular in the 1960s, offering better accuracy and durability than pendulum clocks. Atomic clocks, which are the most accurate timekeeping devices, have been in use since the mid-20th century for scientific and precision timing applications.
Why is time measured by quartz clock much more accurate than that with a traditional clock?
Quartz clocks use the natural vibration frequency of quartz crystal to keep time, which is more stable and accurate than mechanical parts in traditional clocks that can be affected by external factors. This stable frequency allows quartz clocks to maintain consistent timekeeping over long periods, resulting in higher accuracy compared to traditional clocks.
What are quartz clock?
A quartz clock is a type of clock that uses an electronic oscillator regulated by a quartz crystal to keep time. The quartz crystal vibrates at a specific frequency when an electric current passes through it, providing precise timekeeping. Quartz clocks are known for their accuracy and are commonly used in everyday timekeeping devices such as wristwatches and wall clocks.
Does temperature affect clocks?
Temperature can affect the accuracy of mechanical clocks as it can cause components to expand or contract, impacting their operation. Quartz clocks, on the other hand, are less affected by temperature changes as quartz crystals exhibit minimal expansion or contraction. Digital clocks are also less affected as they rely on electronic components.

How do quartz clocks work and what sets them apart from other types of clocks?
Quartz clocks work by using a small piece of quartz crystal that vibrates at a precise frequency when an electric current is applied. This vibration is converted into regular pulses that drive the clock's hands. What sets quartz clocks apart from other types of clocks is their accuracy and reliability. The quartz crystal's consistent vibration allows quartz clocks to keep time more accurately than mechanical clocks. Additionally, quartz clocks are typically more affordable and require less maintenance compared to other types of clocks.

Do clocks use magnetism?
Some clocks, especially those with mechanical movements, may use magnetism in their design to regulate or control the timekeeping mechanism. For example, some clocks may use a magnetic balance wheel or electromagnetic coils to help keep time accurately. However, quartz clocks and digital clocks typically do not rely on magnetism for their operation.

Who invented quartz clocks and watches?
Quartz clocks and watches were invented by Swiss engineer, Max Hetzel, while working for the Swiss company, Centre Electronique Horloger (CEH), in the late 1960s. This innovation revolutionized timekeeping by using the highly regular vibrations of a quartz crystal to accurately measure time.
How does a quartz clock keep time?
A quartz clock is a clock that uses an electronic oscillator that is regulated by aquartz crystal to keep time. This crystal oscillator creates a signal with very precise frequency, so that quartz clocks are at least an order of magnitude more accurate than good mechanical clocks. Generally, some form of digital logic counts the cycles of this signal and provides a numeric time display, usually in units of hours, minutes, and seconds. Quartz timekeepers are the world's most widely-used timekeeping technology, used in most clocks and watches, as well as computers and other appliances that keep time.Source: http://en.wikipedia.org/wiki/Quartz_clock
