Zhengzhou Vientiane City, Guizhou Watch Shop, Lanzhou Si Optical Shop. According to the query of Rolex information, we learned that the three domestic authorized dealers are Zhengzhou Vientiane City, Guizhou Watch Company, and Lanzhou Si Optical Company. Of these three, Rolex is a classic brand in the Swiss watch industry. The original Rolex logo was a palm with five fingers spread out, which indicated that the brand's watches were entirely crafted by hand. Later, it gradually evolved into the registered trademark of Crown.
