Hello guys,
Sorry for creating a new thread.
Recently, my grandfather passed on to me an inheritance which included many of his exclusive watch collection.
Other than the President Rolex 18k, the next "Gold" based watch is this Omega Constellation below;
I don't know much about it but, I would appreciate the help in specifications about this particular watch including model and such. Also, if someone can tell me how much they're worth nowadays (specially with the value of gold higher than previous years) that would be nice.
Here are the pictures. I don't have the original box as this was bought around 1979.

 

Could you get a little more glare on the face? We can still see some of it.

Okay, enough ball busting. It's about a decade earlier than 1979. Looks like a 168.017 with a caliber 564 inside. Can't tell you anything else without better pictures, particularly of the case back (inside and out) and movement. You'll probably need a watchmaker to open it. Have it serviced if you plan on wearing that nice heirloom.

 

Just uploaded more pictures in case that helps! Thank you thus far.
