The American 1921 is without a doubt one of the most charismatic watches ever made. With its square case, the crown on the top left corner, and a dial turned half a quarter to the left, it is unlike any other watch. Like no other timepiece, it represents the Roaring Twenties yet hasn't lost any of its appeal a century later. To mark this unique anniversary, Vacheron Constantin has taken upon itself to make a faithful recreation of the original American 1921. The brand only made 24 of them in their year of launch, of which one resides in Vacheron Constantin's private collection.
