Rolex ladies datejust with Presidential band

[Olliebug]

Hi, I am looking at a 1987 ladies datejust. It has the gold presidential band.

However, my concerns are that the history card indicates that it has aftermarket dial (it is black),aftermarket diamond bezel and aftermarket crystal.

I can understand the aftermarket crystal, but what about the dial and bezel?

Would this be considered a “true” Rolex? Especially if I had to get it serviced by Rolex - or even by an authorized dealer?

Would these aftermarket parts lower the value?

I’m definitely not Rolex knowledgeable, but it’s a beautiful watch and in good condition.
