There is Rolex you want there at price almost the same as you get in HK at less 5% of HK Rolex list price.
After tax 8% refund plus some surcharge of foreign exchange using your card, it would be better you could pay in cash or some part in cash to get a better deal.
The price is in Swiss France, which is about 8.03 HK Dollars.
Well, Friend of mine bought the Ref 116000 in Purple which is almost impossible to buy in HK there at Lucerne!
We cannot see DeepSea Ref116660 D-Blue, Daytona Black Ref 116520 and Submariner Hulk Ref 116610LV in display, but I believe they have it in the drawer if you ask them!
Thanks for Watch Fever Secret Agent Susana's input.
