Am I allowed to be furious? DD40 Scam!

[lordoflords7]

Hi all thanks for reading.

So long story short, in July bought a DD40 in rose gold with chocolate baguette diamond face. Gorgeous watch and fell in love with it. I wear it daily and it brings me lots of pleasure. Bought from a local grey-market dealer.

Couple of days after I bought it, I noticed a small "smudge" on one of the baguettes. Brushed it off and moved on.

Today went to another dealer who looked at the smudge and said "it's a finger-print!" He showed me clearly the whorls of the fingerprint.

Anyway, we tracked down the model number from the white tag and it turns out that my watch has had a face swap. It was orginally stardust or some rubbish colour. Cue panic and dismay.

My questions:
1) Can I go back to dealer and give him a and try and get some money back?
2) How do I know the diamonds are real? Or the face indeed is Rolex original?
3) Will it affect resale value? Or should I lose the white tag?
4) Am I upset about nothing and a face swap is "business as usual"?
5) How should I clean the smudge? RSC? Myself?

Any advice is very welcome. Sorry for going on a bit!

(P.s. I can't get a picture that's worth uploading sorry. It's a very tiny smudge but still there!)
