Japanese SANKYO has licensed the brand. Several companies in Guangdong, Jiangsu and Zhejiang have purchased the license and can produce movements under the name sankyo. Although the names are the same, the products are far different. Sankyo is now just a no-name product. It is better to buy music boxes than other brands. If you want to buy a music box, buy one with Yunsheng movement, and don’t buy anything else. If you want to buy more expensive ones, you can choose Swiss Yujue or high-end Lehmans under Yunsheng, but the prices are really expensive.
