Longines A7 Avigation

About this reference

The Longines Avigation Watch Type A-7, reference L2.779.4.53.0 (often identified by its 3592 case designation), was introduced in 2012 and remained in production for approximately five years before being replaced by smaller iterations. Collectors seek this specific reference for its 49mm stainless steel case and its faithful adherence to 1930s U.S. Army Air Corps specifications, featuring a dial angled 40 degrees to the right for pilot legibility. It utilizes the caliber L788.2, a column-wheel single-pusher chronograph movement developed by ETA exclusively for Longines. The black lacquer dial features large Arabic numerals and a date window at the six o'clock position. On the secondary market, this reference typically trades between $2,800 and $4,200 depending on condition and provenance. A notable production detail is the hinged "officer" style caseback, which opens to reveal the movement behind a sapphire crystal, a feature omitted in later, smaller A-7 releases.
