Speedmaster on the RealReal

So, just wanted some opinions here. My wife is so great, she just surprised me with a 2005 Speedmaster with box and papers that she purchased on the RealReal. The watch is in great condition but I don't have a movement shot and I am reticent to open the back in case I want to return it. The watch serial number and the registration card match, links are 849 and all seems legit. It says the watch needs to be serviced (although I don't know if this is just the blanket language they put on all watch sales).

So my questions:
1. Has anyone every purchased something like this from the RealReal.
2. What is the going rate for this if nice and clean, with the doodads, around $4000?
3. Should I hold onto it and gift it to a child once grown, or hold out for the pre-moon birth year I've been hankering for?

Many thanks. Here are a couple. I'm tempted to open the back using a ball but assuming they did check the movement.

And the back.

You make a very valid point. I guess we do get wrapped up in the chase.
It could be I don't trust anything younger than myself. I still wear my grandfather's Timex.

And you are right about my wife. I have a friend who is very much into watches (nothing overboard) but his wife is no fan (of his hobby).

One last thing, which I should have mentioned earlier but .... I've had such a good experience on this forum with vintage watches, it's spoiled me. I'm very much into the 1970s chunky Omegas, so have bought several of different seamsters -- my favorite being the soccer timer. But I've always wanted a speedster (and bought my oldest son one of this same reference (off the forum) for his graduation very recently. It resonated with him that I was giving him a representation of history, and of accomplishment, both of what has been done and what is possible. A good lesson for any child I think.
