About the early 16th century, sometimes thousands of inventions , the first is to use gravity as a power source , this time only be accommodated in a fixed account areas such as tall buildings , walls on which hung the bell , that is to live a chain system Made with the iron hammer , and rotating around the wheel ; was invented to use the spring will operate , which is now winding watches . This time on account reduced a lot in size , like large eggs , can be installed in the pocket , which is invented by the locksmith in Nuremberg, Germany Nuremberg eggs (Nuremberg Egg), all parts of this watch is hand- made , so costs Time-consuming work , and the only watch and everything in between each . Until the 19th century, gradually developed to machine manufacturing, quality control was able to . So far , the name watches very uniform structure , even in the same area , said there are many different methods or translation , but the world lacks unity on the provisions of watch components . Therefore, the Swiss movement manufacturer ETA used to number the first number to represent in order to watch the buying of parts in the industry, when correct. But the movement had the same name national brands , but there are still differences in the structure , code will be different . Watch the operation is the use of leverage , just like swinging back and forth like a repeat , the basic operation of the order of center wheel by winding → → → the third round of the fourth round of the messenger → → → escape wheel balance wheel , and then placed Round of reaction to the messenger bounce a simple harmonic motion in situ.
