I have a couple of these Fuerza Aerea Argentina Omega watches which were procured during the period of President Peron Presidency which ended in 1955.
After WW 2 Argentina was a powerful and rich Country and procured (imported from USA and Europe) ) the best in armaments and equipment for our Armed Forces... including watches from Rolex, Omega, Tudor and Heuer.
But these watches are found today (not easy to find indeed) in a very poor condition as they were used and sometimes abused during their armed forces times and then they were sold to civilian hands (wrists) who didn`t take good care of them. It is almost impossible to find an example like yours. Big congrats my dear friend: you own the best of the best.
I will post my two watches later when I arrive home.
Keep enjoying and loving this piece of history so much my dear friend.
Best cordial regards, Abel
