This is a Longines flyback chronograph produced around 1940, featuring the legendary Caliber 13ZN in a stainless steel cylinder-design case. It boasts a highly rare and unique silver two-tone snail dial.
The rare two-tone dial features a distinctive design: bar indexes at 12 and 6 o’clock, with Arabic numerals arranged in a roulette-style layout elsewhere. The two-tone coloration and the snail-style tachymeter add a sense of compact sophistication, enhancing the piece’s overall design appeal.
The cylinder case, with its elegant stepped lugs, is beautifully crafted, showcasing Longines' hallmark robustness despite being non-waterproof. It houses the renowned Caliber 13ZN, which comes standard with a flyback function. Among the wide variety of vintage chronographs, this model undeniably ranks among the very best.
Longines’ in-house chronograph calibers hold a firmly established place in horological history, and this masterpiece is no exception. It is a watch whose value and legacy will continue to be recognized and appreciated for generations to come.
