One of the most recognizable, classic, 1950s-Mad Men era wristwatches ever made is the Longines Flagship, which is as solid a representation of the iconic notion of a “men’s dress watch” and/or “a good Swiss watch” as anyone has ever seen (all that buy-in to the latter concept contributed in no small part to the demise of the American watch industry, but that’s a story for another day). It was 1957 when the first Flagship came out and these three new commemorative versions are about as picture-perfect as a vintage watch homage gets.
