Question 1: If it's a tax refund, it's best to use your brother's credit card. If the credit card is not enough at one time, it will be handled in batches. Use your card to make up the brush. The credit card tax refund record must be consistent with the passport holder's, so as to submit the tax bill and refund the tax at the airport. You can refund the tax to your brother's account and transfer it to you after returning home.
Question 2: All Swiss watch shops and souvenir shops can use debit cards with the logo of "UnionPay" issued by banks in China, and the exchange rate will be settled twice. (China domestic bank 1 time; Swiss merchants 1 time).
The third question: if it is a watch with a price of 20,000-30,000 yuan, it is not much different from the domestic price, and the discount plus tax refund is about 5,000 yuan; If it is a 50,000-60,000 watch, the price difference is more than 1 1,000 yuan. (Swiss merchants like cash settlement, and the preferential margin is large; If you swipe your card, the discount range is small, which is of course related to the bargaining level. )
Question 4: Ordinary China tourists buy more Omega and Longines in Switzerland, but people who really know watches prefer Rolex, such as myself.
Question 5: You don't have the exact model of Blancpain watch, so I can't tell you the exact price, but my brother bought a small Blancpain gold watch with a calendar in Hendry, Tianjin. At that time, the price was10.4 million RMB. When I arrived in Switzerland, I found that the watch was discounted and the tax refund was only over 90,000 RMB. (In fact, the more expensive the watch, the greater the price gap with China. )
Finally, before your brother goes to Switzerland, you should do your homework, edit your favorite watch brand, picture and domestic price, then print it out and let him take it with you. Just choose three according to your own preferences. Some watches are not necessarily in stock in Switzerland. After all, many people in the world go to Switzerland to buy watches, where the styles are complete and the shipments are large. Ask if you have any questions! I hope I can help you!
