Longines Lindbergh Hour Angle

About this reference

The Longines Lindbergh Hour Angle reference 989.5215, often identified by its 86-millimeter case diameter, was produced in a limited series of 10 pieces around 1987 to commemorate the 60th anniversary of Charles Lindbergh’s transatlantic flight. This specific reference is valued for its massive .925 sterling silver case and its use of the caliber L989.2, a high-frequency automatic movement featuring twin barrels. The dial follows the original 1931 design with a rotating silver center disc and black Roman numerals for calculating longitude. Due to the extremely low production volume, these watches rarely appear on the secondary market, typically commanding prices between $25,000 and $40,000 depending on provenance and condition. A notable auction result occurred at Christie’s in 2017, where a well-preserved example sold for approximately $32,500. This reference remains the largest modern reproduction of the navigation instrument Longines developed with Lindbergh.
