This is a Mickey Mouse watch. The hand-winding mechanism is broken. The hands move, but it can't be wound. So, if you're interested, please get it fixed. Size is about the size of a 500 yen coin. Thank you. Feel free to ask questions. ① About 17 Jewels There are many pivots inside a wristwatch. Most are for gears, but there are also pivots for the rotating balance wheel and springs. These move precisely with a small amount of force, but to keep them running accurately for decades, wear on the bearings is out of the question. Therefore, to minimize wear, components made of natural (artificial) gemstones are used in the bearing parts. Rubies and sapphires are used. Both stones are suitable for bearing parts because they have ① hardness, ② are resistant to wear, and ③ do not easily generate heat. The number of these stones used in a single watch is indicated by 8 jewels, 17 jewels, or 23 jewels. 17 jewels means 17 stones, and 23 jewels means 23 stones. It is said that the more stones there are, the longer the lifespan and the more accurate the movement, but it's just a matter of giving a sense of luxury depending on the number of jewels. There was a time when the number gradually increased, but in reality, 17 jewels are sufficient. Some stones are used. The gold is probably gold plating, but I'm not sure.
