Moeris Grand Prix

Hello everyone :)

Was wondering if anyone know's anything about this particular watch???

All I know is that it is a Moeris Grand prix, and that it was purchased in the 1970's.
And also that it has a Demi Hunter case.

I do not know if it is gold or not?

Perhaps it is just rolled gold, or gold plated?

Your opinion and comments would be much appreciated.

Many thank's

Robert
