Longines Twenty-Four Hours Heritage Model L2.751.4.53.4

A thoughtfully executed modern reissue of the Longines Swissair reference 6603, a rare  (less than 100) and historically significant pilot’s watch originally produced in the 1950s. This contemporary version remains faithful to the spirit and design language of the original, while benefiting from updated manufacturing techniques and materials.

Measuring 47mm in diameter, the case size mirrors the large proportions typical of mid-20th century aviation watches, designed for maximum legibility in cockpit conditions. The oversized onion-style crown further emphasizes its utilitarian roots, allowing for easy adjustment even while wearing gloves. The dial retains the clean and practical layout associated with its vintage predecessor, offering a clear connection to its Swissair heritage.

This particular example is in excellent condition, showing minimal signs of wear and presenting well both cosmetically and mechanically. It is accompanied by its original inner and outer presentation boxes, along with the instruction book and warranty card.
