Prices in Hong Kong are generally above HK$ 60,000 and less than HK$ 70,000. Take shops as an example. There is a difference between parallel imports and licensed goods in Hong Kong. Licensed goods are fine. You can find out what you have in Rolex official website. Everything is fine. Parallel imports refer to Hong Kong banks sent to Hong Kong by Rolex headquarters, but bought by watch shops in other countries. Generally speaking, this is no problem, especially for some large watch shops with the background of Hong Kong jewelry enterprises. It is recommended to buy Hong Kong licensed products or Japanese licensed products. Also, the green ghost is a global bestseller, so you should be prepared to be out of stock. Before you go, you might as well check the phone number on official website and call them to keep it.
If you don't want to go to Hong Kong, you might as well look at the counters in China. If you can get about 15% discount, it is also very cost-effective, saving you money on air tickets and hotels.
