Quartz is most common, but any piezoelectric material such as topaz, Rochelle salt, or even cane sugar could be used.

What does it means a quartz watch?
It is a watch that uses an oscillator based on a quartz crystal to electronically keep time. Older watches used gears and an escape mechanism to govern the speed. In a quartz watch, a precision cut piece of quartz is used in part of a circuit to generate a specific frequency. A quartz clock works similarly, but the quartz oscillator is used to control the speed of a motor.
Why you use crystal oscillator in 8085 microprocessor?
The oscillator provides the basic clock of a microcontroller to be able to execute the instructions in a stable, periodic way. It is often used for other peripherals too, like timer, UART, etc. as frequency base, usually divided by a clock divider for integer factors, or by PLL for rational factors. If the timing accuracy of these functions is not important, a simple RC oscillator can be used. Many microcontrollers have it internally. Accuracy is in 1...10% range. For better accuracy and temperature stability, a resonator can be used. For applications where timing is critical, a crystal can be used. Most micros have built-in oscillator, so only a crystal and two caps are needed. For those which have no built-in oscillator, external crystal oscillator module may be used. There are OCXO and TCXO modules available for very high stability needs.
How does an electro magnet work in a speaker?
The electromagnet is used to vibrate the diaphragm of the speaker and a given rate (frequency) to produce a given sound.
What is quartz crtstal?
Quartz is a crystal. It is the most common mineral found on Earth and is commonly used in making watches and jewelry.
Why do you put quartz in watches?
Quartz usually gets used in two possible ways in watches. The most common way quartz gets used in watches is in the form of a quartz crystal oscillator. When a crystal of quartz is properly cut and mounted, it can be made to distort in an electric field by applying a voltage to an electrode near or on the crystal. When the field is removed, the quartz will generate an electric field as it returns to its previous shape, and this can generate a voltage. The crystal can thus be made to oscillate (vibrate) with a consistent characteristic frequency. Quartz has the further advantage that its elastic constants and its size change in such a way that the frequency dependence on temperature can be very low. In this way, the crystal can produce a dependable signal of known fixed frequency and thus can be used to measure time. Analog watches take this signal and use it to regulate the speed of movement of the hands of the watch. Digital watches can use the signal more directly to regulate when the display changes. Another more obscure application is the use of quartz crystal instead of glass to cover the watch face. The crystalline structure of the quartz makes the appearance a little nicer than when glass or plastic is used - and the quartz is a bit harder and more durable. It also is a bit more pressure resistant so it will occasionally be used this way in dive watches. Very few watches actually do this of course.
What are LCDs and how are they used?
An "LCD" is a Liquid Crystal Display. LCDs are used as parts of computer monitors and as displays in calculators, watches etc.
What are the type of monitors that use a technology similar to that used in digital watches?
LCD - stands for Liquid Crystal Display.
What is the physical standard used to establish the length of a second?
a crystal when cut to specific dimensions will vibrate at a particular frequency when an electric potential is applied across it. The length of the second is standardized by the Cs crystal.
Why are Oceanus watches so expensive?
Oceanus watches are so expensive because of the materials used in manufacturing. these materials may include Sapphire Crystal and some Diamond like coating. These materials are very durable.
What is crystal most used for?
Glasses to drink from.
Why do people wear watches facing downward?
So they don't break the crystal of the watch. My father used to do this all the time. It was a habit from when he was a coal miner.
What are chronometer watches used for?
A chronograph is a specialised watch that was first created in the 1800s and is used as a stopwatch, they are meant to be the most accurate watches to time in fractions of a second.
Is quartz used in watches?
yes, quartz is used in watches and the quartz watches are known as best watches in the world
What is the tachometer crown found on most watches used for?
It counts heartbeats.
What is the function of crystal in IC?
Not sure what your question means. In an IC (Integrated Circuit) the circuit is etched onto a single crystal of Silicon. So the crystal forms the semiconductors within the IC. or Quartz Crystals are used in electronics as stable oscillators. They vibrate at precise frequencies, which can then be used for radio transmission or reception, or can form a time base for clocks or clock pulses, used for digital electronics.
