SOURCE: Is this a genuine Cartier serial number

is the watch real is it says cartier r1628 water resistant swiss made 2301 cc708177 ???

SOURCE: Fake or not

Generally you have to open the watch to see the movement but a lot of fakes are plain workmanship flaws.
A real Cartier will not be made from base metal. It will be made from stainless steel or precious metal.
A real Cartier will most likely be built with screws in the band instead of cotter pins.
When you pull the crown to set there will be no play in the set lever. In other words when you spin it, it will begin to turn the hand immediately and there will be a slight resistance. It will not feel loose.
As stated, the best way to tell is to look at the movement. Cartier uses a high grade Swiss movement most likely marked ETA.

SOURCE: Dont have a problem but

Ebay will protect you if it is a fake so you should call Cartier to verify the service done there. Hopefully they will do that over phone but you may have to go in. They keep excellent records on each watch by the serial numbers. They will have all the records and you can also transfer this watch to your name and address. Good luck, usually the fakes don't provide so much info on the watch the way yours did but go ahead and register it and review the records to be sure.
