  Quartz clock - Wikipedia, the free encyclopedia
A quartz clock is a timepiece that uses an electronic oscillator which is made up by a quartz crystal to keep precise time.
In modern quartz clocks, the resonator is tuning fork shaped, laser-trimmed or precision lapped to vibrate at 32,768 Hz.
If a quartz wristwatch is "rated" by measuring it against an atomic clock's time broadcast, and worn on one's body to keep its temperature constant, the corrected time can easily be as accurate as 2 seconds per month, more than good enough to perform celestial navigation.

 Watch - Wikipedia, the free encyclopedia
Expensive, collectible watches valued more for their workmanship and aesthetic appeal than for simple timekeeping often have purely mechanical movements and are powered by springs, even though mechanical movements are many times less accurate than quartz movements.
Because these watches are regulated by an external time source of extraordinarily high accuracy, they are never off by more than a small fraction of a second a day (depending on the quality of their quartz movements), as long as they can receive the external time signals that they expect.
In the early 1980s Seiko marketed a watch with a television receiver in it, although at the time television receivers were too bulky to fit in a wristwatch, and the actual receiver and its power source were in a book-sized box with a cable that ran to the wristwatch.

 Replacing the Quartz Watch Battery
A quartz watch consists of a quartz oscillating crystal, an electronic circuit to drive it, a means of displaying time and a battery to power the whole system.
The battery in a quartz watch generally rests in a well with a negative battery contact strap on the bottom and a positive contract strap on the side.
In many quartz watches, mainly digital or a combination of analog and digital, the electronic circuit must be cleared before the battery is changed.

Despite their similarity to mechanical watches, it was necessary to develop a new technology to transform the timed intervals provided by the quartz crystal into mechanical energy to rotate the hands.
Quartz is a piezoelectric material, meaning that it generates an electrical charge when mechanical pressure is applied.
Quartz crystals were first used as a time standard by Warren Marrison, who invented the first quartz clock in 1927.

 Quartz Crystal Watch
The use of the quartz crystal is known as the piezoelectric effect.
The piezoelectric effect using quartz crystals was discovered by the Curie brothers in 1880, and in the years following was studied extensively by them.
They found that when quartz and certain other crystals are stressed, an electric potential is induced in nearby conductors and, conversely, that when such crystals are placed in an electric field, they are deformed a small amount proportional to the strength and polarity of that field.

 How do quartz watches work?
Quartz timepieces use the nature of the quartz crystal to provide a very accurate resonator which gives a constant electronic signal for timekeeping purposes.
Quartz crystals can be cut at a consistent size and shape to vibrate at thousands of times per second, making them extremely stable resonators for keeping very accurate time.
Their quartz clock was a very large device as compared with today’s quartz wristwatches which also use microchip and liquid crystal display technology.

Most high-end watches are automatic meaning they do not use a battery at all rather they are powered off the motion of the wearer.
This refers to a watch that has undergone a series of precision tests to verify that the automatic movement keeps proper time and doesn't fluctuate, with either plus or minus, more than an allotted time within a 24-hour interval.
Mechanical Movements are hand-wound, In hand-wound watches the mainspring is fastened at one end to the inner surface of the barrel and at the other end to the core.

During the 1970s, the "quartz watch" burst onto the scene as the newest high-tech gadget.
Initially, these watches had red LED displays and they cost around $500 in the United States.
Since then, the quartz watch has evolved so that either an LCD or a traditional mechanical (hour and minute hand) movement displays the time, and the price has fallen dramatically.
