The only thing you can make an issue out of with the seller is the fact that the hands are (probably) relumed.
Normally, with expensive pieces, prices of hands are known. If it would be say a 5513, than relumed hands are 200 euro where Original are double.
You can discuss that price difference.
But the fact that everybody says you paid too much, you need to forget.
They Always say that, because they rather would have sold a watch to you themselves, but didn't. And if you were in the market for another watch, you would turn to them first. Because they would not rip you off, they sell value for money. You now think.
And if you would want to sell the watch (to them), you were already softened up for the price they would offer you.
Basic "professional" seller tactics. (not meaning to offence sellers here)
