Time tells history and clocks tell time. People may be born with the idea of time, but the instruments used to measure time units are not. Their emergence and development are closely related to human practice.

The "sundial" is a kind of measuring the time by using the position of the sun (one hour is equal to two hours). It consists of a needle to generate a projection and a dial with the time engraved on its face. It appeared before the Han Dynasty (206 BC-AD 220).

The science of horology, originally subordinate to astronomy, in the course of its development has been connected with mathematics, physics, chemistry, geodesy, navigation and machinery. With the beginning of the Industrial Revolution, science and technology developed by leaps and bounds, and mechanically powered timekeepers began to emerge in Europe.

The timepieces developed by Yu Xuan are based on classical clocks and watches from Britain, France and Germany. The shell of the timepieces is mostly of non-ferrous metal structure, mainly copper, and the surface decoration is mainly wire cutting enamel, painted enamel, stone inlaying and copper carving. The color is elegant, its form has church building type, screen type, trophy type, locomotive type, car type, bird cage type and so on. Its internal structure changes more, with falling weight as the power of the rolling clock, to steel ball as the power of the pressure clock. At the same time also make full use of the spring as the moving source of gear linkage system, installed some active figures, birds and beasts and water white, etc. Some clocks are also equipped with "thermometer", "weather table", "eight tone bell", "compass" and other instruments, and there are two kinds of gold-plated and antique antique treatment. In the production process to seiko imitation for the purpose. With modern techniques, with traditional technology imitation, giving timing and art in one, the parts are made of a single piece, after the fine grinding, polishing, plated 24K gold and imitation of old processing, by senior watch technicians carefully assembled, debugging, simple, elegant, noble.

Since its birth, the clock has played an extraordinary role, becoming a medium of mutual understanding and a tool of communication between the world. From the wonder of the early Western missionaries to the acceptance of the world, from the acquisition of royal goods to trade with each other, there are clocks. Clocks spread and were accepted around the world at a speed unmatched by any other Western object. More important is the world's influence on the concept of time.

The clock is not only a time-keeping tool, but also a messenger of cultural exchange and communication.

Behind the dazzling clock gives us a more historical reverie and a deeper understanding of home accessories.
