Probably an Omega De Ville from the "Symbol" series, model BA 196.0316. 4530.62.00 is the Omega PIC number, but in this case it's more likely 4430.13.
Due to being quartz, a bit small by today's sizes and not an "in" style the value is less than many mechanical vintage watches.
The bezel is 18 karat solid gold, it has the original strap and it's in reasonable condition.
You can check eBay for recent sales to get an idea of value.
