Roc - msrp, purch price, retained value

[airchitect]

So, first and foremost I have only recently even began to consider AP as an add to my small collection and one "single" watch fits the bill.....the ROC. Now I'd love either a blue or black dial but know nothing about the AP market. I know msrp is about 23k but beyond that, what should I expect to pay at an AD? what discounts have you guys worked out? hows the value retention? Stepping from Rolex into another brand feels like walking through a mine field! But man thats a damn fine watch
