First, what it said electric China Rolex Replica, electronic watches? Broadly speaking, any machine with button batteries as the energy of the watch list are called electric watches.
Narrowly speaking, electric watches are mechanical watches specifically refers to the process of development of electronic watches a transitional type of watch, put it in a similar shaft mosaic of semi-circular disc nail artificial stones, so that the pendulum swing axis swinging round brush plays a role, the existence of such a watch is not long, not more than the number of production.
In the future course of development, the application of electronics in electric watches without devices, such as diodes, integrated circuits and the like is called electronic watch, the only part of the electricity of course watch electronic watches.
So far, the world watches the production of mechanical watches and electronic form only two categories.
The electronic watches from the mid-1960s, although this China Rolex Replica Watches For Men, century study successfully developed a new type of watch, but because of advances in science and technology, especially the rapid development of electronic technology and new materials industries, electronic watches in a short historical period has witnessed a upgrading several rapid progress that has undergone several updates from nature.
As has been widely recognized by the international community as the watch: the balance spring electronic watch – mechanical watches with high frequency accuracy and battery as the energy output of the working process of a very stable combination of both electronic watches; electronic tuning fork watch – stable oscillation frequency of the use of electronic tuning fork watch; Analog quartz electronic watches – Applications quartz piezoelectric effect and pointer display combines electronic watches; digital quartz electronic watches – Applications quartz piezoelectric effect and diodes or LCD combines electronic watches; microwave electronic watches – using satellite broadcast signal error-free and ultra-miniature microwave receiver combination of electronic watches.
Currently, the international student off monopolized almost all electronic watches quartz digital watches.
Specific figures are the most convincing evidence, from the production of varieties and production in the world watches you can clearly see it.
Watch the world’s total output in 1975 was 224 million, of China Rolex Replica Watches which quartz electronic watch production was 7.17 million, accounting for only 3.2%.
After 16 years of development, to 1991, the world watches the output reached 828 million, of which Analog quartz watch production was 472 million, accounting for 57% of the digital quartz watch production was 232 million, the two together, quartz watch accounted for 85 percent of the world watch the annual output; mechanical watch production was 124 million, accounting for only 15%.
Thus this short 16 years of quartz electronic watches developed from an annual 7.17 million to hundreds of millions of only 7.04, an increase of 98 times.
In 1991 world production of all electronic watches quartz watch, quartz watch and pointer has an annual output of 2 times digital quartz watches.
Although in 1991 to now watch the world changed a lot, but still a monopoly of quartz electronic watches electronic watches, quartz watches 486.html outside the industry even became electronic form in lieu of that.
Watch how long should be cleaned once, which should be determined according to the following aspects: (1) the extent of the sealing of the watch.
If the seal is good, can be a bit longer interval; (2) The quality of oil is good or bad.
If the table is not volatile oil, is not lost, not bad, can be cleaned once a few years; (3) according to the conditions of use.
If the environment is clean, not often open the back cover can also be used a little longer time to clean.
Watch because of the seal is not good, easy Diaspora table except oil,Rolex Replica Watches For Men volatile and dry outside, watch the oil is dirty, bad, negative force will cause the bearing friction increases, the loss of flexibility in gear, reducing transmission efficiency, along with the swing happen to go change will have serious watch lockout.
Watch Table oil addition to their differences in quality, its various parts of the lubrication fuel and lubrication are not the same, the change of the oils are different.
Points on the table fork tile oil, due to the escapement wheel punch, lock collision between tile surface and fork, table oil flows easily be scraped or other non-work surface, soon attracted the diaspora, loss or dry This is the watch lubricated deterioration of the most powerful parts of the state, usually a year or so there will be no oil state.
Table oil wheel drive bearing portion of each department at the Rolex Replica Watches general lubrication state can be maintained for two years or so, basically dried up three years later, there are only a few traces of oil or oil film.
Put oil drilling table, due to the oil shock protection device has a role, mostly in one or two years, still maintain good lubrication; about three years, most only a thin film; basically in a dry state after four years.
If care is uneven or oil drilling gap is inappropriate, it will Diaspora in the side after oil.
Center wheel and wheel over the journal, due to the larger load bearing oil film between the journal and the diamond is often easy to squeeze, dry friction phenomenon occurs locally, the journal wear was worn plating or metal oxide-based experience rust, so watch oil deterioration, appear brown or reddish brown phenomenon, increasing friction, thereby increasing wear.
General decline in the table at the swing after three or four years and take a more significant change.
The classics, if a new table, sealing degree and work environment are good, cleaning time may be extended, but not to exceed a maximum of five years for the degree of general seal watch every two or three years should be cleaned regularly refuel once, in order to maintain oiling parts to maintain good lubrication.
