Great topic, Mark . . . and your top five (or is it nine?) is a great group of chronographs. As I read your message, three Autavias came to mind, as favorites / important ones in the history of the Autavia line.

• First is the "Viceroy" . . . this one had the classic black, red and white color scheme . . . whether we are looking at the early ones (Derek Bell) or the later ones, in the larger cases, this is a classic Autavia color scheme. Yes, we love the white, blue and black of the Sifferts, but I have to put the black, red and white of the Viceroys on ths list. I choose the Viceroy model, because it was so popular, and it allowed anyone with $88 to have a fine racer's chronograph.
• Next, I wanted to add the 73633 Israeli military Autavia . . . you have shown the big black one (perhaps for the colonel or general, or the Navy diver), so let's add this one for the sargeant. I see that Jarl had the same idea.
• Finally, I want to add a GMT Autavia to the list, to bring in the red and blue colors. I will add the Zodiac GMT, as a representative of the 2446 Autavias, and also to carry the flag of the "poor men" to the party.

: Autavias is the most iconic Heuer in my eyes.

: I was popular as new, and it's very popular among collectors today.

: One of my favorites is this very simple military watch from Israel
