The so-called mastery of watches is actually a very broad concept. If you can repair watches, you are more proficient in watches than ordinary people, and you can modify them yourself, then you are more proficient in watches than ordinary masters. If you can make your own tourbillon, and the daily difference is within 10 second, you can call it true mastery. If it is an independent watch, even if two zeros are added after 2000 yuan, some people will appreciate it. The current problem is that some practical watches in Switzerland are only in their early 3000 s, and they use the basic movements of ETA and SW. If your single watch costs 2000 yuan, then the comprehensive cost of a single watch is about 2300-2500 yuan, including publicity and platform charges. Your cost is too high for a non-printed watch with no mass base. . .

However, you can try to make a few finished products first and hang them on a famous watch forum in China to see the reflection. However, no matter the case, waterproof performance and shock absorption, you have to make a bright spot before your cousins will have the intention to buy. But for most people who don't know anything about watches, your method won't work. They would rather buy 800 Casio. . .
