Old West Watch mainly depends on the movement model (marked in the table).
As for how much it is worth, it depends on how old and new your watch is and whether it is broken!
Normal ones can sell for 2000 to 5000 (depending on the old and new degree and brightness)
Gas needle (western, Chinese), a Swiss brand, was founded in 1886.
Founded in 1886, it has gained a certain popularity in China in the 1950s, especially its military watches. As the saying goes, "with an air needle, you are not afraid of a deep beard." In the Sino-Indian border war, China used this watch to reward the winning soldiers. When looking for an object, the other party saw that the People's Liberation Army had an air needle watch, and knew that it was a cadre of this division. Cadres who had never married a harem became the first choice for beautiful women in the station. So there appeared the famous saying "With an air needle, you are not afraid of getting a deep beard". As long as you have it, it is a symbol of status, no matter how you look, you can marry a beautiful woman. There are also night lights to promote that "air needle" can be used for reading. Although it is a bit exaggerated, the "air needle" is really good at night light.
