3k is reasonable, especially if the majority of the scratching is to the bracelet and the case is in overall good shape, which is what this looks like. Per @dsio's added eBay link, the seller has the same description.

If you plan on buying it I think it is a reasonable deal just go into it with your eyes open. You will likely need to account for the cost of a service, and if you like that bracelet just have it polished up. Me personally, I would also factor in the cost of a newer gen bracelet or strap.

Probably the right call. One will come along! I agree with @chiefenergy strongly: set a definite budget and buy the best example that you can get within that budget, especially if it is a watch that you plan on hanging on to versus flipping out of your collection in a couple of years.
