Help! Buying a Speedmaster Racing for proposal

Hello! 😀

I just bought this watch on Chrono24 for proposing to my current boyfriend and I'm a bit nervous!

I have no experience in buying high end watches, so I would REALLY appreciate any feedback on whether this looks legit. Also, any advice on how can I make sure it's original once I receive it the US?

Thanks so much in advance!
