  The origin of the wall clock


Wall clocks were originally evolved from tower clocks. In the 16th century, there were huge tower clock buildings in Europe. Due to the manufacturing technology at that time, clocks were generally larger. With the development of technology, the breakthrough of quartz clock technology in Japan in the middle of the 20th century and its application in clocks.
Small wall clocks are popular in thousands of households. At present, there are three major types of wall clocks: 1. Analog quartz wall clocks 2. Mechanical wall clocks 3. Digital wall clocks. Wall clocks are necessary in some halls and rooms, especially in general offices. Clocks should be used in these places, because they can have five functions: one is to recruit wealth, the other is to avoid evil spirits, and the third is to help the owner with luck. It is under the management, and five is time. However, if you do not know how to hang the clock, you will not be able to hang it in the wrong place. The front of the clock cannot face inward.
