When you go to Hong Kong, you should consider after-sales service. Moreover, Hong Kong itself is a mature second-hand and refurbished market. Many things are invisible in appearance, especially watches. It is recommended to buy locally. Professional consultants will give you good service and take care of everything after sale. You can go to the TAG Heuer counter on the first floor of Yaohan. They are brand stores, and the goods are the latest and most complete. Don't be greedy and bury hidden dangers for the future. In fact, you should buy it abroad. Travel expenses and taxes should be increased. We should promote the mainland economy and stop increasing the income of foreigners.
