Thanks for the long winded introduction. I really feel like I know you. Your watch is as Swiss as South American cheese. It's native to South America. Really quite unique. So unique I think it may be one of a kind...
As @BenBagbag is saying with a hint of sarcasm, the watch isnt an Omega. Everything about it is fake.
Let's have a guessing competition as to what movement hides inside the "18K Gold" case. My entry is an Adolph Schild Caliber 1130, 13''' (AS 1130). Maybe even engraved with "OMEGA" and possibly "Seamaster".
