Have had a chance to look at my AJTT.
Pages 713/4/5 are great to reference thank you.
Omega did produce some very short runs of bespoke and obscure enamel dials - like coats of arms - but also maps of countries such as Brazil and Palestine.
However, they are all of very high quality and all have the Omega symbol.
So, I'm more than ever convinced that the 'Arabia' or 'Saudi' dial at auction is an after market addition and may be a one off.
A quick snap of Omega enamel dials, from AJTT, for those that are interested.
