As with anything on eBay, feedback is everything. There are quite a few sellers in Singapore that have very good feedback because they sell authentic watches for less. You can buy right from their eBay storefront or wait for something good to come up on their auctions to really save money. Often you get a warranty (not sure if it would be honored by the manufacturer) and full packaging. Other times you might not get packaging or an owner’s manual. I have personally bought two watches this way, saving hundreds of dollars each time. They arrived quickly, were 100% authentic and came with full packaging. Keep in mind the high shipping costs with these dealers. One of my purchases was shipped air freight that added around. I was aware of this ahead of time and figured it into my bidding.
