Hello everybody, I just bought a 1963 cal 853 and was trying to research it a bit. I found this site: which states that both rose gold on steel as well as the "dubble logo" was uncommon on the cal 853 Ingenieurs. I was wondering if this is true for the automatics? and if so how many might have been made? I don't have much of a camera right now so i included the pictures from the seller here:
thanks!
