When did humans begin to have the concept of "time"?
The distant ancestors of mankind first knew that time would pass from tomorrow. About six thousand years ago, "Zhong" first appeared on the stage of human history: the sundial was born in the kingdom of Babylon. The ancients used sundials to master time according to the length and orientation of the sun's shadow. 4000 years ago, the leaky carving came out, enabling people to know the time day and night. Clocks and watches appeared after the middle of the thirteenth century.
/kloc-the early mechanical clocks that appeared in northern Italy and southern Germany around 0/270 were powered by a weighing hammer, which rang the attached clock every hour and automatically struck the time. 1336, the first public clock was installed in a church in Milan. In the next half century, clocks and watches spread to European countries, and churches in France, Germany and Italy built bell towers one after another.
Soon, the clockwork technology was invented, and the size of the clock was greatly reduced. 15 10 years, German locksmiths first made pocket watches. At that time, the production of clocks and watches seemed to be limited to the sideline of locksmith. It was not until later that the accuracy of clocks and watches became higher and higher, and the skills of clocks and watches became more and more complicated, and professional watchmakers appeared.
1806, a watch specially made by Napoleon's wife and queen J. Jopifen is the earliest known watch record. This is a watch that pays attention to decoration and makes bracelets. At that time, pocket watches were very popular in men's world, and watches were regarded as women's accessories.
1885, the german navy ordered a large number of watches from Swiss watchmakers, and the practicality of watches was affirmed by the world and gradually popularized.
At the beginning of this century. The predecessor of Rolex-Wilsdorf &; Davis Company launched silver gentlemen's watches and ladies' watches, which was a great success and led watch manufacturers to compete to develop watches. Switzerland, which is famous for its pocket watch skills, also took the lead in making watches. 1926, Rolex developed a completely waterproof watch "ROLEX OYSTER", and in 193 1, it took the lead in bringing the self-winding watch "OYSTER PERPETUAL" to the market. Longines is not to be outdone, and its precision aviation clock flies across the Atlantic with American pilot Lindbergh, making it famous. 1929, CHRONOGRAPH, a watch with stopwatch function, came out, and CHRONOMETER, a precision watch for flight, was developed on this basis the following year.
At the end of 1960s, the history of mechanical watches turned a new page: 1969, Seiko Watch Company developed the world's first timely electronic watch, and the daily error was reduced to less than 0.2 seconds. 1972, Hamilton Company of the United States invented the digital display watch, and the motor and gear disappeared from the watch.
New technologies in watch manufacturing are emerging one after another, but mechanical watches have not died out. Although the output was greatly reduced, the manufacturing skills remained. Swiss watch manufacturers, in particular, still have a soft spot for mechanical watches, insisting on producing high-grade mechanical watches and exporting them to all parts of the world.
