First time Rolex buyer- help needed!

[bubbles6789]

Hello!

I'm shopping for a watch for my fiance's 30th birthday trying to stay around the ~2k mark.

I found this watch and was wondering if anybody could help me verify if it's real, its value and give me a "condition grade" based on other used models you've seen (is this in good condition?). I'm just extra worried, as it has insurance documents, however it doesn't have an official proof of authenticity (however the seller has a very positive previous Rolex sales rating). Pictures attached! 


Also, opinions or suggestions for a model for a younger guy would be greatly appreciated!

Thanks!
