Online Watch purchase. What actions should I take if I do get scammed?

[gatorned]

I have recently ordered a new Seiko Ananta watch online through a private seller that appears to be reputable, although, honestly I was not too sure of. Normally, I would have proceeded with caution, however due to certain circumstances, I went ahead and made the purchase anyways. I understand that Paypal would cover my full purchase price.

In preparation for the unlikely outcome that I have indeed been mailed a brick, what actions could I take?

Would I be able to recover the fees/taxes I would have to pay for customs?

Once I do receive the watch, is there anyway I can verify the watch is indeed new and not pre-owned (I guess except by the private seller)?

all i can say is if you spend a bit of time and do some research which is easy on here then you would know to order from and who not to im sure everything will be fine we as noob buyers just need a little patience sometimes

Could I learn anything about the watch's history from its serial number?

If so, how?
