Quartz crystal in quartz watches work on the principle?
Quartz is a naturally occurring silicate mineral composed of silicon dioxide (SiO 2 ). Its hardness is 7 on the Mohs scale and it is in the trigonal crystal system. Quartz pos…sesses a glassy luster and does not exhibit cleavage. The average specific gravity of quartz is 2.62. Quartz can be found in all three rock types, igneous, metamorphic, and sedimentary. Quartz has a white streak, but specimens can be appear colored by impurities or exposure to heat or radiation to hues of white, pink, red, orange, yellow, blue, green, black, smokey, milky, or purple. Quartz is a mineral, chemical composition of silicon dioxide, one of the most common minerals on the planet.
It works by using the piezoelectric effect: if a small voltage is applied to a specially prepared crystal of quartz it vibrates at a definite and almost constant frequency whi…ch can be used to power a tiny motor to turn the hands of the watch.

Quartz is the second most abundant mineral in the Earth's continental crust, after feldspar. It is made up of a continuous framework of SiO 4 silicon--oxygen tetrahedra, wit…h each oxygen being shared between two tetrahedra, giving an overall formula SiO 2 . There are many different varieties of quartz, several of which are semi-precious gemstones. Especially in Europe and the Middle East, varieties of quartz have been since antiquity the most commonly used minerals in the making of jewelry and hardstone carvings
Quartz crystals are the naturally occurring crystalline structure of the mineral (quartz) with an atomic arrangement of silicon and oxygen, chemical formula SiO 2 , forming in… the hexagonal crystal system.
No, mechanical and automatic watches are powered by a mainspring, quartz watches are powered by a battery. A mechanical watch needs to be manual wound by the crown and is lack…ing a rotor. An automatic watch is wound by a rotor that tightens the mainspring, it can also be manually wound by the crown.

Quartz and mechanical watches use vastly different technology to power movements. A quartz crystal watch uses a tiny battery to electronically power the movement. A mechanical… watch uses a balance wheel and hairspring. Hand-winding the mechanical watch powers the movement. For more information please refer to the related link below:-

Both quartz and rock crystal are made up primarily of silicon dioxide. The main difference between them is that rock crystal does not have any significant amount of trace elem…ents that would color it. Quartz does contain coloring trace elements.
Quartz has the property of being piezo electric. It can bend with electricity or produce electricity by bending. Cutting a quartz crytal to precise dimensions will allow it it… resonate when stimulated. Electronics in the watch use the crystal in an oscillator circuit to produce a frequency, typically 32,768Hz. This can be divided down using electronic counters, to give one pulse every second. In an analogue watch, this one pulse is applied to a stepper motor which moves the second hand, one second. Gears from the second hand drive the minute and hour hands like a conventional watch. Digital watches use an LED or LCD display, driven by counter circuits that advance one second at a time.
Quartz is a piezoelectric material. This means that it vibrates when current is passed through it. It also means that when it is vibrated or put under pressure, it generates c…urrent. When current is passed through a quartz element, it vibrates, which in turn puts some current back into the circuit. This creates a feedback look that creates a waveform in the electrical signal; this wave can then be used as a clock by using electronic components to measure the number of wave cycles that have passed. This means that quartz is an integral part of any timing circuit, and timing is important for watches, computers, and anything that requires coordination between different parts.
