Extended data:

19 14 when the first world war broke out, the military of various countries realized the importance of "hands-free" watches, which stimulated the urgent demand of ordinary people to wear watches. 1926, the first self-winding watch was invented. Since 1960, traditional round watches have been widely liked by people.

The further improvement of Swiss watches is to miniaturize the chronograph, calendar, tourbillon and automatic clockwork of pocket watches and install them on watches. 1952, electronic watches made in America, France and Switzerland.

1967, the electronic watch center in Neuchatel developed the first timely watch, and started mass production under different Swiss brand names in 1970. Since then, new technologies have developed rapidly, and different brands of watches have also developed rapidly.

For genuine watch brands, what can be observed by the naked eye is the vertical wheel, vertical fork and balance wheel of the watch.

If you know a little about the material of watches, you can find the difference between copper and steel. Generally speaking, the vertical wheels and forks for real watches are made of steel.

Because in the use of steel, not only in surface polishing, but also in weight and wear resistance, it is better than copper. On the balance wheel, the color of the balance wheel of world-famous watch brands is mostly gold, and the material is generally beryllium alloy or zinc-copper alloy, and beryllium alloy and zinc-copper alloy are mostly used in aviation production.

So the grade is very high and the material is extremely expensive, which truly reflects the difference between famous watches and ordinary watches.
