Is this vintage 18ct solid gold Genéve Crossdial worth it or even a fake?

Hello,
I stumbled upon this Omega Genéve from 1968 and thought: "Wow, this is beautiful", and then I saw that it was solid 18ct gold, and that really caught my attention because it was only listed at $770.

But is a watch like that even worth that much, and is the gold in the watch worth that much? Or is it too good to be true? I'm not that good at vintage watches, so I thought I'd ask a bunch of experts here on this site😀

Thanks!

Looks redialed to me.

So you’d say, it’s not worth the $770?

Yes, more like 500$
