It's always a pleasure to help an enthusiast,
even a good goldsmith can make in casting the case .
In the 1970s , many of the datejust , day date , president , were duplicated with cases remade in casting by goldsmiths ...... the beginning of replicas
I believe i need to found a good goldsmith, just received a reply from Phong and they no longer provide real gold case
I remember the first case made by goldsmiths, here in Italy was very popular a fake daytona in real gold!
