I agree with all that the P has to be more exclusive than the R. But in order for that to happen, they have to produce it for only two years. Then what is left for the 5270? All metals have been done except a J, but that doesn't seem like the end of the line.
My only concern was the salmon dial. Some shots make it look lighter and some richer and with a deeper hue. I'm sure the dials are consistent, so it's the photos. The photo on this thread makes it look perfect.
I have a 5270P on order with a delivery date of January 2020. I had never tried the watch in the metal and yesterday I had the chance to try a 5270R, Never worn, but traded in by one of those collectors who buys multiple Patek's a month and trades them without having worn them. There was no wear on
