Now this is a difficult one to answer. Volume, location, level of greed and quality should play ionto the equation. Some may be cheap some may be inexpensive compared to other dealers watches but finaly one has to take a good look at the pictures and what movement that is driving these pieces to make that call. There is no complete answer to your question.
You should know that some watches with Asian movements can be had for a very very low price over there where they are being produced.
