OMEGA Constellation questions (168.009?)

Hello I inherited a Gold Omega watch from My father and I would like some help with IDying the watch, knowing how I should sell it (I’m from Portugal) and if we have any idea on its market value.

I was not able to get it open yet since the Omega store is in Lisbon and I live far away from it.

The bracelet itself has the number 368.845.

From my research it appears it’s a 168.009.

If I bring it to the store would they evaluate it?

Thank you in advance and sorry for the dump of questions, I’m just pretty overwhelmed with all this new information I am trying to compile.

Beautiful watch and very fashionable these days, it'll probably sell easily.

Βefore you sell it, make sure you're certain you won't regret it - I mention this because when it comes to family heirlooms, once they're sold, they're gone, and it's hard to get them back.

Τhis refers to the US market, but it's a very informative article on how the scrap value of gold jewelry is calculated here. For the watch, you'll need to subtract the weight of the non-gold parts (movement, crystal, etc.)
