Watch for most people it is a necessary accessories. Although its basic function is to tell time, it also can be used as a luxury. For 
many years, have a lot of development time mechanism. Early a down weight, to track of time. The pendulum of the invention provides a more accurate timing method, but even if this technique can not well adapt to portable watches. In addition, these watches to talk after regularly, otherwise they will stop working. Then how do the quartz watches work?
For those who are not familiar with the origin of the interests of quartz, this is common, because it is in the sand of the sea as the sand of the sea. Quartz watches essential attribute is the ability of the natural vibration when the pressure on its scientific called piezoelectric effect. This pressure can be in the form of mechanical movement or charge. In other words, you can make the crystal of dance and jumping depends on surprising is very similar to the one pressure. Based on embedded crystal a watch also need to function as other parts of the timing devices. Because the reaction of quartz, taking the electric power, the battery power is part of the standard. Because it is a watch, the battery capacity is usually quite small.
The working principle of the clock is through the quartz crystal power, make its in a fixed frequency oscillation. Crystals have a natural oscillation in 32000 hz or so. Your vibration producing a small current, this is the “points” by the internal circuit frequency required. In a simulated watch, these pulses used to move within a table of mechanical gears. In digital watches, integrated circuit continue to count pulse, because they added up to a few minutes, a few hours or even days.
Because of the frequency is the constant and precise quartz watch is very reliable, in the test, even if is the lowest quality production quartz watch accurate to less than about half a second each day, more accurate production upscale quartz watch has the measured accurately, the second in less than 1% this year.
Although the precise measurement of the time request, the occasional differences, because components and the surrounding environment supporting. As the body movement part exist, friction and wear, can lead to a second time in here and there. The temperature changes, the crystallinity of subject the smallest beat shaking. Quartz watch mechanism, so that they can perform many other functions, such as computing and storage telephone number. Watch the innovation of recent may for using quartz.
