Longines Spirit Flyback Green Dial Men 42mm L38215532

Celebrating Longines’ historic invention of the flyback chronograph in 1925 and blending heroic aviation heritage with precious-metal craftsmanship, the Longines Spirit Flyback 42mm L38215532 stands as a premier technical triumph in Swiss pilot horology . Forged in a commanding 42.00 mm surgical-grade 316L stainless steel case crowned with an 18-karat yellow gold cap (200 microns) on the bidirectional rotating bezel, screw-down crown, and chronograph pushers, this model features satin-brushed surfaces, polished bevels, and an ultra-hard green ceramic bezel insert with luminescent markings . The dial showcases a rich, matte sunray green finish with gilded accents, applied Arabic numerals, and five applied gold stars—the historic hallmark of Longines' highest-grade movements—alongside a bi-compax chronograph layout beneath a domed anti-reflective sapphire crystal . Powered by the exclusive in-house Calibre L791.4 column-wheel automatic flyback movement certified by the COSC (Contrôle Officiel Suisse des Chronomètres), it operates with an antimagnetic monocrystalline silicon balance-spring and delivers a robust 68-hour power reserve . Mounted on an interchangeable green calfskin leather strap secured by a double-security folding clasp with an integrated micro-adjustment system, it provides 100 metres (10 bar / 330 feet) of water resistance and is protected by an official 5-year Longines international warranty .

Design & Craftsmanship

Pioneering Aviator Heritage & The 42mm Two-Tone Gold Cap Architecture

Longines filed the patent for the world's first flyback chronograph mechanism in 1935 (registered in 1936), equipping legendary aviators such as Richard Byrd and Amy Johnson. Measuring 42.00 mm in diameter, 17.00 mm in thickness, and 49.50 mm lug-to-lug, reference L3.821.5.53.2 carries this historic DNA into modern luxury . Forged from surgical-grade 316L stainless steel, the case combines vertical satin-brushed case flanks with mirror-polished bevels. The bidirectional rotating bezel ring, knurled screw-down crown, and dual pump pushers are encased in an 18-karat yellow gold cap 200 (a thick, durable layer of solid gold bonded to steel) . A dark green polished ceramic insert completes the bezel, offering scratch immunity and tactile grip for pilots and navigators .
