Newbie with an old Rolex

[k1ngfl1pper]

Hello all. I inherited my first Rolex - 1966 Datejust Turn-O-Graph from my father in law. I just got it back from it's overhaul (needed new crystal as well as some other work) and I'm thrilled. I have no intention of selling my watch, but instead will be handing it down to my son (who's only 5 months old now) when he's old enough to appreciate it (or when I pass on). My only concern is, I don't have any of the original documentation or box. Any help pointing me in the right direction to make sure my Rolex has everything it needs would be greatly appreciated. Thanks for having me here!
