Not a President or Air King
Yesterday we saw an article about how President Elect Barack Obama wears a Secret Service Chronograph and before that he wore a Tag-Hauer.
I saw in a post that Leo put up on WatchTalkForums.com that people have suggested McCain wore an Rolex Air King. In this photo from November of 1982, you see John McCain with his wife Cindy the month he was elected to the United States House of Representatives from the state of Arizona.
It appears to me that in the photo below, John is wearing a Rolex Datejust.
