Question on gold Omega Constellation Quartz 1333, could be rare

I recently inherited the Omega Constellation Quartz watch pictured here. I went to a watch repair store to get it checked out, and it was confirmed that the whole thing is 18k gold. (The bracelet number is 398.0856.) After doing some research online, it looks like a 1333 model from the late 70s or early 80s, though it doesn't seem like many of these were made in all gold.

I'm not attached to it, but not sure what to do with it. It runs, but needs to be fixed since the date doesn't turn over and the clock isn't consistently keeping time. I'd be happy to sell it just for the gold, but not sure what type of money this could get me. (The watch guy guessed $1,500 at the low end.)

Any advice, insights or guidance? Should I try to get it fixed and sell it as a watch, or is there not enough of a market for this model? And if I did, what's a reasonable price to ask? Or is the best bet to just sell it for gold? Is the watch guy right on what I could get for that?

Thanks!

Not much of a market for these as a watch so it comes down to melt value. I would imagine a pawn shop would give you the price per gram once the movement has been removed.

The movement can't weigh very much so you can just weigh it to get a ballpark value.
I'm a sucker for Quartz Omegas but sorry to say this one doesn't press too many buttons. It must be pretty narrow too, 32 mm ?

Actually the dial on this one does not appear to be solid gold (no OM markings).

Keep the watch since gold prices will stay rising 😀

Hi, if you still have it, i am interested in buying thé watch.
