Newbie Alert! Any issues with this day date?

[kkumarcpa]

Hello all,

I have been reading this forum for a while but recently joind as I am going to take the plunge and buy a ref 118238 day date.

I want one with diamond hour markers and a black, blue, or silver dial.

I found the one pictured below but it doesn't have papers and I'm wary of making such a big purchase without knowing as much as I would like. So I figured I would reach out to you experts for your advice.

The seller says its 100% rolex, but that parts may have been updated as part of routine servicing.

My biggest concern is that this may be a frankenwatch and I wouldn't even know.

The seller is Capetown Diamonds if that makes any difference.

Any thoughts, comments, opinions would be greatly appreciated.
