Longines continues to maintain a close and long -standing bond with the aviation world. The brand produced a large number of watches and chronographs for pilots, on -board equipment and other navigation tools that contributed to the development of civil and military aviation during the first half of the twentieth century. Today, Longines is giving new life to this fascinating inheritance with the watches of his “Heritage Avigation” collection.
