Spirit Chronograph Flyback 39.5 Stainless Steel / Blue

Ref. L3.721.4.93.9

The Longines Spirit Pilot Flyback L3.721.4.93.9 debuted in 2026 as part of the Longines Spirit collection, a line that references the brand’s historical involvement in aviation timekeeping and pilot’s watches. The model features a round stainless steel case fitted with a ceramic bezel and is water-resistant to 10 bar. The bezel is bi-directional rotating and forms a functional element of the watch’s pilot-oriented design. The case is equipped with a scratch-resistant sapphire crystal with several layers of anti-reflective coating applied to both sides. The dial is finished in matte blue. Applied Arabic numerals serve as hour markers, while silvered polished hands indicate the time. A small seconds display is positioned at 9 o’clock, contributing to the instrument-style layout associated with pilot’s watches. Power is provided by the Longines calibre L792, a hand-wound mechanical movement beating at 28,800 vibrations per hour. The movement offers a power reserve of approximately 68 hours and drives the central hours and minutes together with the small seconds indication at 9 o’clock. The L3.721.4.93.9 is fitted with a blue rubber strap secured by a buckle. The strap is equipped with the Longines interchangeable system, allowing it to be easily replaced without tools.
