NM, personally, I am sure.. But I have always believed that watch collections are such an individual thing, that no two collections could ever be the same, so, to keep a long discussion short, (with respect) that statement is my belief, and I totally respect yours and anyone elses thoughts towards other watches. OTOH. Here's the case back of my Heuer Autavia Argentinian Air Force Insignia and number. (Tool if there ever was one) Reportedly to have seen air time during the Falklands / Malvinos conflict.
