A travesty of the Omega Constellation Megaquartz

The parts do have value, as these are difficult watches to maintain well & parts can be hard to find. Your best bet is to list them on eBay.

Real shame the watch was broken up, but I guess you know that 🙁

From what I recall, the movements are hard to work on. So unless you really know what you're doing with it, you could easily go down another rabbit hole it you want to rebuild it. Well, assuming you can find the parts you need...

Personally, I would sell it as it is. Then someone who knows what they're doing can take it for spares. There are collectors and specialist watchmakers who want spare movements like this as back up in case they need to cannibalize parts in future.

That said, if you know your way around the movement and don't mind getting stuck with random bits that don't sell, you could try breaking it down and selling it for individual parts. I doubt that's worthwhile for most people, but you might feel differently.

We used to have a UK member who specialised in these, but he hasn't been around for a long time.

Actually, you might want to contact Simon Freese as he used to service these for members who had them. He's a UK watchmaker a lot of us use. You can get his details by googling him. Even if he doesn't want to buy what you have, he might give you a better idea of what to do, or of value.

Update - I've remembered that it's @Tom Dick who is into these & he's still around 😗
