this is the Rolex Daytona, in 18k yellow gold. The Daytona only comes in 40mm. The reference number of this watch is 116528. The current price of this watch is $29,500. You should be able to get a good discount on it though!
am looking around for a datejust rolex, shops in uk refused to give me discount when i asked! back in asia, authorised dealers and even rolex shops are readily to give me one, but i dont see myself going back to the tropics too soon...
