Today, Longines combines the original beauty of the most remarkable of its former products with cutting-edge watchmaking technology. The Heritage models are a tribute to the pioneering spirit that has inspired Longines designers since the company's early days. The brand's products accompanied many pioneers in their adventures in the air, on land and under the sea. The very core of Longines timepieces is based on this expertise. They demonstrate the continuity of a brand and that brand's continual ability to pay tribute to history through refinement and elegance. Among the exceptional pieces in the Heritage range, the most famous is without question the Lindbergh Hour Angle Watch, a re-issue of the timepiece developed for the American pilot Charles Lindbergh in 1931. The Longines Weems Second-Setting Watch, a tribute to the navigation system devised by Captain Philip van Horn Weems, and the Longines Twenty-Four Hours, a re-issue of a watch designed especially for Swissair pilots in the 1950s, also feature among the stars of the Heritage models.
