Authentic Moonwatch? Help!

I’m trying to buy a wedding gift for my fiancé in the form of a vintage Speedmaster Moonwatch as we both love space etc etc etc ... but I know NOTHING about watches, whatsoever. Neither Omega nor any other brand.

I came across this one on eBay and thought it looked cool but obviously (1) missing a photo of the back, (2) weirdly has a booklet from 2011 despite being a 2017 Omega archive purchase of a 1976 watch and (3) not a ton of detail on what exactly the original band is that the seller has removed.

That said, if I could resolve these issues I still don’t know if this is legit. I did research the bezel and it looks like it could be an genuine DNN version that would have been around in 1976 but that’s based really on one online resource.

I’m sorry if I’m not posting this properly but would be very appreciative of guidance!

As noted above, the price will go higher. And it will need a service for use so allow another $500-1000 for that. That seems a lot to spend based on a few pictures with some important information missing.

Is 1976 important for you? It just has quite a few unknowns and you could end up spending many thousands for a watch that won't turn out to be exactly what you want. It's a lovely thought to buy such a watch, though these vintage watches can be a minefield. You'd normally want to do a lot of research and choose something that is sold with a warranty as you're not a watch person.

I assume you're not interested in a new Speedmaster? This could be bought to tie in with your engagement or wedding and will be special because of that. At least you know it will all be correct and come with a five (?) year warranty.

Good luck, Chris
