A lot of bros have pm me on more information of watch shops in Singapore . So to cut the story short and make your hunt easier . Make a trip to bencoolen plaza , their are many shops on the same floor selling watches , rolex, iwc , pam , even to casio or seiko. After which, popby to golden landmark hotel which is 5mins walking distance . There is a shopping mall inside the hotel which also have many shops selling preowned rolex.
As for website , just google the names that I had posted in the pervious thread and u sure can find. Normally, all of them closes around 7pm . As I was informed by mod not to list out all the shops name and received too many pm, those who are keen , please read from this thread and google their website. If still cannot find, then I try my best to help u but rewards is kopi and roti on u if I am in Subang
