Very cool and looks to be in really nice condition.
These have got to be damn rare for this simple reason that in the Shah's Iran there couldn't have been many people that could afford such a watch. I wonder if the elite were a powerful enough market for Omega to produce these in some limited numbers for retail sale or if they are more of a custom-type order?
I know this thread is old, but I thought I could add to the historical context here. My father tells me that back in the time of the Shah, there were actually quite a lot of watch stores in Iran, especially in the main cities. My family lived in Tehran, but he travelled all around the world (and throughout Iran) as part of his job in big pharma. He was a "watch guy" and so he purchased many watches throughout Iran. When I asked him about watches with farsi characters, he said the reason you don't see them very often is because people typically purchased the same models that were available throughout the world. As far as brands, he said the higher end brands you would typically see on well established people were Omega, Rolex, and Fortis. Breitling was also a brand that was seen, but typically it was on pilots. In fact, there is a model that they made at the request of the Shah, that he gifted to the "top guns" in their air force. Otherwise, people wore Seiko and Citizen quite a bit, especially post-Quartz days.
Also, it's unfortunately a popular myth that there were not many well to do people at the time of the shah. Peoples' financial situations were definitely better than today. :/ I was young when we had to escape the country due to the crazy theocrats, but everyone who lived through the time of the Shah and then afterward tells the same story of going from a wonderful time to a terrible time.
Sadly, my family escaped with very little in terms of possessions, but they brought over a gold women's Omega and a gold Fortis.
Very nice Omega here, I'd love to get one.
