Tianjin Seagull
Tianjin Seagull Watch Group () is a watchmaking company located in Tianjin, China. Founded in 1955, it is the world's largest manufacturer of mechanical watch movements, producing one quarter of total global production by volume. History The company was originally formed as Tianjin Watch Factory in January 1955 with four craftsmen on order of the People's Republic of China government. In 1990, the Tianjin Watch Factory was awarded the status of a national company, and in 1992, the Tianjin Seagull Corporation was founded. That same year, the decision was made to discontinue the production of mechanical watches in favour of quartz watches; five years later it came to a complete reversal of this decision. It has since produced exclusively mechanical movements and watches. In 2000, Tianjin Seagull Watch Group went public, and in 2003 a representative office in Hong Kong was opened. In 2010, the company moved to new production and administration facilities near Tianjin Airport. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tianjin (; ; Mandarin: ), alternately romanized as Tientsin (), is a municipality and a coastal metropolis in Northern China on the shore of the Bohai Sea. It is one of the nine national central cities in Mainland China, with a total population of 13,866,009 inhabitants during the 2020 Chinese census. Its built-up (''or metro'') area, made up of 12 central districts (all but Baodi, Jizhou, Jinghai and Ninghe), was home to 11,165,706 inhabitants and is also the world's 29th-largest agglomeration (between Chengdu and Rio de Janeiro) and 11th- most populous city proper. It is governed as one of the four municipalities under the direct administration of Chinese central government and is thus under direct administration of the State Council. Tianjin borders Hebei Province and Beijing Municipality, bounded to the east by the Bohai Gulf portion of the Yellow Sea. Part of the Bohai Economic Rim, it is the largest coastal city in Northern China and part of the Jing-Jin-Ji megap ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
China
China, officially the People's Republic of China (PRC), is a country in East Asia. It is the world's most populous country, with a population exceeding 1.4 billion, slightly ahead of India. China spans the equivalent of five time zones and borders fourteen countries by land, the most of any country in the world, tied with Russia. Covering an area of approximately , it is the world's third largest country by total land area. The country consists of 22 provinces, five autonomous regions, four municipalities, and two Special Administrative Regions (Hong Kong and Macau). The national capital is Beijing, and the most populous city and financial center is Shanghai. Modern Chinese trace their origins to a cradle of civilization in the fertile basin of the Yellow River in the North China Plain. The semi-legendary Xia dynasty in the 21st century BCE and the well-attested Shang and Zhou dynasties developed a bureaucratic political system to serve hereditary monarchies, or dyna ...

Watch Movement
A watch is a portable Clock, timepiece intended to be carried or worn by a person. It is designed to keep a consistent movement despite the motions caused by the person's activities. A wristwatch is designed to be worn around the wrist, attached by a watch strap or other type of bracelet, including metal bands, leather straps or any other kind of bracelet. A pocket watch is designed for a person to carry in a pocket, often attached to a chain. Watches were developed in the 17th century from spring-powered clocks, which appeared as early as the 14th century. During most of its history the watch was a mechanical device, driven by clockwork, powered by winding a mainspring, and keeping time with an oscillating balance wheel. These are called ''mechanical watches''. In the 1960s the electronic quartz clock, ''quartz watch'' was invented, which was powered by a Battery (electricity), battery and kept time with a vibrating quartz crystal. By the 1980s the quartz watch had take ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mechanical Watches
A mechanical watch is a watch that uses a clockwork mechanism to measure the passage of time, as opposed to quartz watches which function using the vibration modes of a piezoelectric quartz tuning fork, or radio watches, which are quartz watches synchronized to an atomic clock via radio waves. A mechanical watch is driven by a mainspring which must be wound either periodically by hand or via a self-winding mechanism. Its force is transmitted through a series of gears to power the balance wheel, a weighted wheel which oscillates back and forth at a constant rate. A device called an escapement releases the watch's wheels to move forward a small amount with each swing of the balance wheel, moving the watch's hands forward at a constant rate. The escapement is what makes the 'ticking' sound which is heard in an operating mechanical watch. Mechanical watches evolved in Europe in the 17th century from spring powered clocks, which appeared in the 15th century. Mechanical watches are ...

Hong Kong
Hong Kong ( (US) or (UK); , ), officially the Hong Kong Special Administrative Region of the People's Republic of China ( abbr. Hong Kong SAR or HKSAR), is a city and special administrative region of China on the eastern Pearl River Delta in South China. With 7.5 million residents of various nationalities in a territory, Hong Kong is one of the most densely populated places in the world. Hong Kong is also a major global financial centre and one of the most developed cities in the world. Hong Kong was established as a colony of the British Empire after the Qing Empire ceded Hong Kong Island from Xin'an County at the end of the First Opium War in 1841 then again in 1842.. The colony expanded to the Kowloon Peninsula in 1860 after the Second Opium War and was further extended when Britain obtained a 99-year lease of the New Territories in 1898... British Hong Kong was occupied by Imperial Japan from 1941 to 1945 during World War II; British administration resume ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tourbillon
In horology, a tourbillon (; "whirlwind") is an addition to the mechanics of a watch escapement to increase accuracy. It was developed around 1795 and patented by the Swiss-French watchmaker Abraham-Louis Breguet on June 26, 1801. In a tourbillon the escapement and balance wheel are mounted in a rotating cage, with the goal of eliminating errors of poise in the balance giving a uniform weight. Tourbillons are still included in some modern wristwatches, the mechanism is usually exposed on the watch's face to showcase it. Types of tourbillon Single axis tourbillon Patented by Breguet in 1801, the single axis tourbillon minimizes the difference in rate between positions caused by poise errors. The tourbillon was invented to complement the split bi-metallic balance which was inherently difficult to poise. In the most common implementation of this, the tourbillon carriage is carried by the fourth pinion, within a stationary fourth wheel. The escape pinion is engaged with this ...

Chinese Standard Movement
The Chinese Standard Movement, also commonly known as the "Tongji" (Chinese: 统机, "unified") movement, is a mechanical watch movement that was developed in the People's Republic of China during its fourth Five-Year Plan in the 1970s. It was designed by engineers from several early Chinese watch factories as part of a Ministry of Light Industry initiative to consolidate the industry, and with a few exceptions it became mandatory for all factories to discontinue the production of their own movements and to mass-produce the standard movement. Because of this, the production of the standard movement defines an entire era in the history of Chinese watchmaking. Once the most commonly produced mechanical/automatic watch movements in China, the numbers produced and their quality (at least for a majority of produced movements) have since declined significantly; today the movement lives on typically in simple (even crude) automatic and skeletonized (i.e. using hollowed-out parts and s ...

Manufacturing Companies Based In Tianjin
Manufacturing is the creation or production of goods with the help of equipment, labor, machines, tools, and chemical or biological processing or formulation. It is the essence of secondary sector of the economy. The term may refer to a range of human activity, from handicraft to high-tech, but it is most commonly applied to industrial design, in which raw materials from the primary sector are transformed into finished goods on a large scale. Such goods may be sold to other manufacturers for the production of other more complex products (such as aircraft, household appliances, furniture, sports equipment or automobiles), or distributed via the tertiary industry to end users and consumers (usually through wholesalers, who in turn sell to retailers, who then sell them to individual customers). Manufacturing engineering is the field of engineering that designs and optimizes the manufacturing process, or the steps through which raw materials are transformed into a final product. T ...
