r/rolexauthentication

Can you confirm if this is authentic based on these photos? I’m asking for the photo of the movement to be sure.

I work a minimum wage job and my regular randomly tells me he wanted to gift me a watch. I thought it was gonna be like a cheap watch but I saw that it’s Rolex. But I’m hoping it’s fake since there’s no one one would pay this much for a watch for someone who just makes their coffee 😭

I was given a Rolex that was apparently my great grandfathers. I know nothing about Rolex so I am trying to authenticate it and get an idea of what it may be worth?
