How are standard watches made?

The watch is an ancient timekeeping tool, which is said to have originated in China. It is shaped like a circular plate and consists of a series of rings with different sizes, each ring represents a different time or time unit. When using the standard to measure, you only need to put it on the plane, and then choose the appropriate ring to measure the time according to the specific needs.

Gauge is a very accurate measuring tool, which is most commonly used in astronomy and military measurement. In astronomy, the standard table can measure the position and angle of the stars, thus calculating the trajectories of the sun, the moon and the stars; In military survey, the standard table can measure long-distance objects and distances, and can be used to make operational plans and tactics.

Although modern technology has developed to the point where electronic instruments can be used for more accurate measurement, standard watches, as a traditional tool, still retain its important role. In the context of the upsurge of modern humanism, standards have also been given more cultural and symbolic significance. Guibiao is not only a measuring tool, but also a symbol of traditional culture, which is of great significance to inherit and carry forward Chinese culture.
