The Longines Avigation Bigeye

Longines continues to keep a close and long-standing connection with the world of aviation. The brand has produced a large number of pilots' watches and chronographs, on-board equipment and other navigation instruments which aided the development of civil and military aviation during the first half of the 20th century. Today, Longines is bringing this exciting heritage back to life with watches from its "Heritage Avigation" range.
