Bobbee, this is a nice watch.
I do, however, question the Air Warden name, and here's why. We have at least three Air Warden advertisements, and they all show the "5" and "7" partially hidden behind the subseconds dial. We have examples of Air Wardens in the database that show this same dial configuration, so we know it existed. The overlapping of the dial elements would appear to evidence a slightly smaller diameter case, but I don't think we've confirmed that with measurements.
I also note that the examples we have of this watch with the dial that matches the ad are all white dialed, rather than black, a phenomenon that I can't explain, considering we have no ads showing a white dialed Air Warden. They all may be incorrectly identified. I have one of the white dial models myself. The only black dialed "Air Warden" in the database does look just like yours, but we have to consider the possibility that it is mislabeled.
So, what do you make of the dial layout on yours versus the ads and the other examples in the database?
If you'd like we can compare case measurements between your black dial model and my white dial model.
Below are the three ads, as well as a pic of my white dialed "Air Warden".
