Longines Spirit Flyback 39.5mm

Longines Spirit Pilot Flyback L3.721.4.53.2 – The Pioneer Chronograph Redefining Precision

The Longines Spirit Pilot Flyback L3.721.4.53.2 is a masterpiece that combines history, innovation, and watchmaking precision. This manual-winding chronograph, crafted in stainless steel and ceramic, pays tribute to Longines’ pioneering heritage and its fundamental role in developing flyback technology, patented by the brand in 1936.

Flyback Technology: A Historic Function Designed for Aviation

The flyback complication allows the chronograph to be reset and restarted with a single action—ideal for timing successive flight stages. Originally designed for professional pilots, this function is integrated here with absolute precision thanks to the L792 caliber, a manual-winding mechanical movement beating at 28,800 vibrations per hour and offering a 68-hour power reserve.

In addition, the movement features a silicon balance spring, resistance to magnetic fields, and chronometer certification (COSC).

Sophisticated and Durable Design

With a diameter of 39.50 mm, this Spirit Pilot Flyback is built in stainless steel and ceramic, offering the perfect balance of robustness and elegance. Its details include:

• Bidirectional rotating bezel

• Water resistance to 10 bar (100 m)

• Balanced dimensions: 47.40 mm lug-to-lug, 20 mm between lugs, and 13.40 mm thickness

• Total weight of 103 g

Impeccable Legibility in Any Situation

The matte black dial with applied Arabic numerals and gold-tone hands features Swiss Super-LumiNova®, ensuring outstanding visibility. The chronograph includes:

• Central chronograph seconds hand

• 30-minute counter at 3 o’clock

• Small seconds at 9 o’clock

A design created for functionality without sacrificing the modern and refined aesthetic of the Spirit collection.
