The difference between the RETAIL price of 5170J and 5170G
... appears to fit the pattern that Patek has traditionally charged for a J versus a G, as dr kol has noted.
However that is an apples-to-apples comparison of the RETAIL prices of the two pieces. What dr kol seems to be discussing above (and please correct me if I'm wrong) would be the spread between what he would have to pay if he bought a NEW 5170G by selling his CURRENT 5170J at prevailing prices in the secondary market for pre-owned pieces. As such, he is bringing up questions like "why might a pre-owned 5170J be trading at such a discount versus retail" and "if the 5170J was discontinued, would secondary market prices begin to rise, as with previous discontinued models."
But - such discussions are most likely best left to other forums, and is probably not appropriate here!
