Getting a Great Deal on a Rose Gold Royal Oak

[Farris]

Guys,

I have created a short list of watches I love and am trying to identity which one I can get a great deal on new or used.

Here they are in order of preference:

1. Patek Nautilus Chrono All RG (this is very expensive and unless I get a great deal, out of reach)
2. AP Equation of Time
3. AP Skeleton Perpetual Calender Chrono
4. AP All RG Royal Oak Chrono - Black or White Dial

Can you guys please give me help with identifying what these can be had for as % off MSRP and if any can be had as a great deal used with box and papers?

Thank You
