Omega oversize 18ct 285 movement

[Nickn]

I bought this 18ct gold 40mm oversized omega today
There is no model markings inside the case only 18ct on the back
Does anyone know which model it is?

There is no model, it is a locally made case with an Omega movement.

Thanks
I believe this was quite common after ww2 when gold couldn’t be exported
That’s why lots of omega in the Uk have Dennison cases
Any idea which country?

Given the time period, my guess would be Argentina or Brazil.

US, UK, France and Italy all had specific hallmarks that they used back then.
