A small wrist watch is just a common accessory,both man and women,elder and younger like to wear the watch only for the style and function of timing .so do the evolutionary history of the watch be ignored.Have you ever think of the technology behind your watch?

A small wrist watch is just a common accessory,both man and women,elder and younger like to wear the watch only for the style and function of timing .so do the evolutionary history of the watch be ignored.Have you ever think of the technology behind your watch ?
Long time ago, the watch is one of the timepiece.our ancestor utilized many ways to get the time before the timepiece.For example,Sundial used for estimating the time accoding to the position of the sun ray,the Funnel used to record the time by the flowing sand.the Funnel is called the"sun watch"or"sand watch"by people .But this is not a true watch.because the fundation of a watch is the oscillation period.
Dating back to the 14th century ,the first wind up watches come up, and were carried in your pocket. the basic components are still similar with the watch in today. The following parts are used in a wind up watch:A spring,An oscillator,A numbered dial,Two hands,Gears.That necessary parts form a simple workable watch.the power produced by the spring,the time base come from the an oscillator,the gear for the ticking rate on the dial.
In the 1960s, Bulova replaced the oscillating balance wheel with a transistor oscillator which is a new technology that time. It is a new technology used a tuning fork,the applied method is almost the same regular rate between the transistor oscillator and the turning fork.However,this is a more accurate method of keeping time was still being sought.there is only 1 second difference with the actual time oneday.
During the same period,the new technologies such as integrated circuits and LED technology whcih is less expensive and highly accurate technologies were introduced. But there is a problem that these new technologies could be applied only if a battery be small enough to match a watch.How to finding a new skinny element to fit the watch instead of the big battery ?Under the demand of devolopment of then human.And the quartz crystal was decided upon as the new element after study one generation by another generation . the most advantage of the quartz is that quartz maintains its crystalline properties,even when exposed to intense heat.The accuracy of the quartz is unaffected by most solvents and very accurate. it produces an electronic charge by compressing a crystal.Thin sheets of quartz are plated like an integrated circuit and chemically engraved to make these crystals which make the watch be small and delicated.
From that time ,a tuning fork shaped crystal is used in most of the modern quartz watches.precision of the angle of quartz cut with respect to the crystalline axis. The accuracy is also affected by the amount of contamination allowed to get through the encapsulation to and onto the surface of the crystal.To keep good indifferent time ,the watch maker must pay attention to the cut method of the quartz. Today most of the quartz in watches has one-second pulses, which are driving a small electric motor that connects to gears to move the hands on the face.
Also nowadays the digital watch is used by more more people because of accuracy and variety in design .the ring of the crystal comes from the oscillation created by the electronics inside the watch amplifying internal noise.and Then converting this to digital circuits by pulsation.
the machinery watches is the orignal of watch,a period that the quartz watch nearly drove the machinery away,since the high cost and complicated winding up equipment.But in the recent years,the machinery watch come over and is popular with the high-class society.In the channel of time ,the machinery become the new spoiled fashion again.
At this time,people are busy in work,punctural time is more important,the level of the life is the middle between the devoloped and the poor,common people can not object the charming of the brand watch but limited by the much expensive price.Since that ,the replica watch come out by the requirement of the society.The replica Rolex,replica omega watches,Replica Baume Mercier Watches are sold very well the result of the survey show.
From the development of the watch ,we known that the devolopment depend on the technology and the concept of the fashion that time.
