bcoz as d electronic watches now available use vibration of a crystal of a substance called quartz to mesure time . d frequency of da vibrting quartz crystal in side these cloks n' watches is so regular dat dey lose or gain only 1s every10 years.....

What is the difference between quartz and automatic movements in watches?
Automatic watches are self-winding ie. they need no battery and are wound by the slightest movement of the owner's wrist. Rolex invented the modern automatic back in the 1930s. A quartz watch is powered by a battery - it keeps time by pulsing electrical current through the tiny quartz crystal, which oscillates at a predictable rate and hence keeps very accurate time. Quartz watches can have either an analog dial with the traditional hands or have a digital display - or both.
Quartz crystal in quartz watches work on the principle?
Piezo-electric Effect
How do quartz watches work?
with a magic wand
Why it is written quartz in watches?
This refers to a Quartz Movement which means the watch is battery powered
What do the different movements of watches?
The two main categories are mechanical and quartz. Mechanical watches are split into two categories: manual and self-winding (aka automatic watch). Mechanical watches are powered by a wound spring that drives the gears. Automatic watches have a small spinning weight (called a rotor) that helps wind the spring which powers the watch. Manual watches rely on the watchwearer to wind the crown (knobs on a watch). Quartz watches are mostly powered by batteries and use the fast vibration of a quartz crystal to keep time.
Is quartz used in watches?
yes, quartz is used in watches and the quartz watches are known as best watches in the world
What watch keeps the best time?
So-called "atomic wristwatches" keep the best time. They keep time as well as quartz wristwatches during the day, and they receive radio transmissions at night with the correct time. All "quartz wristwatches" keep excellent time -- they drift less than 15 seconds a month when they are worn (kept close to body temperature) -- even low cost watches well under $30. Analog quartz watches and digital quartz watches have the same accuracy. Mechanical watches are not as accurate as quartz watches.
Are Quartz watches the best over digital?
Quartz watches actually use quartz crystals to keep time. Quartz is related to the time keeping mechanism. Quartz watches can also have digital display.The word 'digital' refers only to the display and not mechanism type.
What is used in quartz watches that helps to give accurate time?
A quartz chronometer will employ an electronic oscillator that enables the timepiece to record the passage of time - see related link below for additional information .
Do quartz watches have a battery?
Yes all quartz watches need a battery to work.

Does quartz watches contain moving mechanisms as well?
Yes, many quartz watches have real moving hands for second, minute and hour.
What mineral is used in watches?
quarts

What kind of precision instrument is quartz found in?
Quartz is used in timepieces such as watches or clocks.
