... It is so nice and nostalgic to view those old ads.
I feel they are referring to both Pan American and Swissair with those words about two famous Airways Companies.
It is suggested by the little drawing of a Douglas DC 6 or 7 airplane with the Swiss cross on its tail.
We have always read about the connection of Rolex/Pan Am giving birth to the GMT, but never about Swissair, so this add is very interesting and a Great finding!
Have a nice day friends!!
Very cordially, Abel.
