Weekend score, Omega Constellation

Hey All,

I picked up this watch over the weekend from a local antique store, not being a huge fan of quartz I was reluctant, but it was thrown in with the purchase of some other furniture and artwork to close the deal...

So now I own a quartz watch and I don't feel as dirty as people have made owning one out to be 😝

I figured at a minimum I can use it as trading fodder to help get something that I like.

I cannot seem to get a grasp on what these go for, champaign star dial and all, so if you have any input there I'd appreciate it. Just so I know what I could reasonably expect trade value wise.

Thoughts? As far as I can tell, other than needing a cleaning it's authentic, but if I'm wrong there please let me know. The deal on the other stuff was already solid, this was just icing on the cake so I'm not too worried about it.
