The first is religious persecution.
It took more than 200 years for Switzerland to become a watchmaker. In 1792, close to the French revolution, some of the citizens who supported it fled under the threat of the government. Most of these refugees came to the industrial city on the ruffah border, also Besancon city on the edge of the Jura mountains.
With no land of their own for farming, protestants from Switzerland mostly chose to work in the French national watch factory in the city of Besancon. In the prosperous past of the clock industry, Besancon was the most important chronometer producing area in France. Its peak period spanned from 17th, 18th and 19th centuries until the middle of the 20th century, with its radiation reaching all over Europe and even Asia and Africa. Although Besancon has a mature manufacturing industry base, it is a pity that Besancon has been losing local technical talents due to religious and political connections. Nearby Switzerland takes a lot of advantage.
By 1799, napoleon had returned to France and built his empire. Atheist, he reinvigorated the emerging political system, further weakened the power of religion in clever ways, and he lifted the persecution of jews and protestants, the first step toward ethnic pluralism and the subordination of religion to government in France, while reshuffling power in Western Europe. At this time, the persecuted protestants, backed by the powerful French, returned to their native Switzerland, bringing with them the latest horological techniques and the political ideas of the republic. Later, these former refugees became the mainstays that propelled the development of the watch industry in the Swiss regions of La chaux-de-fonds and Le Locle. There is also a saying that focuses on a watchmaker named Daniel Jean Richard, who is said to have first come to Le Locle and persuaded local farmers to make parts for him during the winter months when he could not farm.
The second is the heresy.
There were patent laws in places like Britain and France. A clutch of laconic French watchmakers, seeking to evade patent laws, went to the Swiss border, then a no-show zone, to make copies. In the cold winter, cats make clocks and watches in their houses, and when the spring flowers are in bloom, they take the finished products to European countries to sell. They also hired local migrant workers to make parts for them, so slowly the tabulation technology took root in Switzerland..
Whether it's a witch hunt or a heresy, Swiss watchmaking is now a world leader. Chinese people have a saying: heroes do not ask the source. It's all a joke.
