Longines Spirit Pilot Flyback Manual Wind Chronograph, Black Dial on Bracelet [L3.721.4.53.6]

The Longines Spirit Pilot Flyback Manual-Winding Chronograph 39.5 mm [L3.721.4.53.6] is a highly engineered pilot’s instrument that blends historical aviation inspiration with contemporary chronograph innovation. Designed to honor Longines’ legacy in aviation timekeeping, this model features a robust stainless steel case paired with a black ceramic bezel, creating a technical yet refined aesthetic.

The matt black dial offers exceptional legibility with applied Arabic numerals and gilt hands treated with Swiss Super-LumiNova®, complemented by two chronograph sub-dials and a flyback function that enables instant resetting and restarting of the chronograph with a single action — a practical feature for timing successive intervals in dynamic environments.

Powering the watch is a manual-winding mechanical movement featuring a flyback chronograph complication, beating at 28,800 vibrations per hour and delivering a power reserve of approximately 68 hours. This movement is officially certified as a chronometer by the COSC, underscoring Longines’ commitment to precision and reliability. Longines

Securing the timepiece is a stainless steel bracelet with a double safety folding clasp and micro-adjustment system, combining comfort with secure wear. A scratch-resistant sapphire crystal with multi-layer anti-reflective coating protects the dial, and a bidirectional rotating bezel enhances timing versatility. With water resistance to 10 bar (100 metres), this Spirit Pilot Flyback is both a capable tool and a distinguished statement of aviator heritage.
