Detailed Product Description: | Dongguan electronic watches parts manufacturers mechanical clock is a mechanical watch with a hammer or a spring release energy as the driving force to promote a series of gears operated by the escapement governor regulate speed gear train to the pointer indicates the time and measurement time of the timer . Electronic clock electronic watch is a modern electricity appeared to show a digital timer and quartz pointer powered LCD. Watches have always been one commodity favorite people. Since the founding of New China, the state has invested heavily in the development of the watch industry, the rapid development of the industry so that, after the reform and opening up and globalization of China's economic development to Chinese watch industry brought prosperity. After decades of development, the Chinese watch industry has experienced a feed assembly - Exterior Parts Manufacturing - Product Development - the creation of the development of the brand, currently has a comprehensive range of watch manufacturing industry, all parts are available in addition to the high-end movement outside processing and production. From a regional pattern of view, the country has been formed to Guangzhou, Shenzhen and the Pearl River Delta region as a leader, six watches, Fujian, Zhejiang, Jiangsu, Shandong, Tianjin and other main producing areas; from the production point of view, China has become the world's largest producer of watches, Clock output ranked first in the world. According to monitoring data Preview Industrial Research Institute Monitoring Center data show that in 2011, China's output of clocks and watches are respectively 159 million and 130 million. Although the development of the watch industry has made considerable progress, but the domestic watch business and its brand reputation and influence in the international market is still insignificant, although the proportion of output has reached more than 80%, but the output value accounting for less than 30%, still no voice and pricing. Watch Industry Development 140 BC to 100 years, the ancient Greeks created the Olympic timer with 30-70 gear system components. [1] -139 year 78 AD Han, Zhang Heng manufacture turn leaking armillary sphere, the celestial globe with a gear system and timing clepsydra banded together to promote clepsydra drip evenly rotating celestial globe, just turn one day a week, which is the earliest mechanical clock. In 1350, the Italian Dante created the first tower clock RBI simple mechanical structure, the difference between day 15 to 30 minutes, indicating that the only organization in the hour; from 1500 to 1510, Germany's first steel spring instead of heavy 亨莱思Hammer, created using crown wheel escapement of small mechanical clock; after 1582 years ago, the Italian Galileo invented the pendulum gravity; in 1657, the Dutch Huygens introduced the gravitational pendulum mechanical clock, the creation of the pendulum clock. 1660 British Hooker invention gossamer, and instead of the crown with a back wheel escapement escapement; 1673, Huygens balance spring in turn composed of the governor applications in portable timepiece; an hourglass hourglass 675 years, Britain's Clement watt device is made with a fork easiest anchor escapement mechanism, this mechanism has been used in the simple pendulum wall clock. 1695, wheel British invention Tom escapement level; in 1715, the British invented Graham escapement still make up less than retreat escapement mechanism for the development of sophisticated mechanical watches foundation ; 1765, Marchi British invention freedom anchor escapement mechanism, namely modern tile escapement fork vertical predecessor agencies; 1728 ~ 1759, the British Harrison produce high-precision standard nautical bell; 1775 ~ 1780, Britain's Arnold created a sophisticated table with the escapement. 18 to the 19th century, the watch manufacturing industry has gradually achieve industrial production, and reached a very high level. 20th century, with the rapid development of the electronics industry, battery-powered clock, AC Bell, electro-mechanical watch, Analog quartz electronic watches, digital quartz electronic watches after another, day difference is less than 0.5 seconds clocks, watches into the Microelectronics technology and precision machinery of the new era of combining quartz Main products: watches accessories and other fasteners, connectors, screws, other connectors, terminals, other plug, other bearings, other electronic hardware, other common hardware accessories, other metal processing, other communication cables, nuts, tube processing, grinding, cutting, rivets, lathe, communication products processing, non-standard parts machining, shaft machining, other mechanical parts processing machinery is a mechanical clock bell with a hammer or a spring release energy as the driving force to promote a series of gears operated by the escapement governor regulate speed gear train to the pointer indicates the time and measurement time of the timer.
