Just purchased 2 Rolexes here and have a question

[RobbieNYC]

I recently bought myself a datejust 116200 with black dial and stick markers from a trusted seller.

Then I got a 179173 from a different seller with blue diamond dial and tt oyster bracelet for my girl.

Now I'm reading where somebody here bought a bnib watch with non-original parts on it. So I'm a little worried. Both sellers assured me my watches were all original, but I don't know enough to tell.

Does the ladies 179173 come factory with oyster tt bracelet and blue diamond dial? Rolex website not showing it that way, does their site show every configuration? My watch is more common and I've seen others that are just like it, I'm more concerned about my girlfriends. Maybe I'm just paranoid, both my sellers had a ton of references. . .
