First Patek – 5226G Available from AD?

I have a very nice Rolex collection and want to add a Patek. I love the 5226G and am needing some advise please:

-Is this readily available from Patek AD? (My Rolex AD doesn’t sell Patek)

-If not, expected wait time?

-Is gray an option for this reference (ie how much are super clones are an issue with Calatrva)?

-Do they come available here often? They seem to be below retail on gray.

Thanks in advance!
