Manufactured around the 1940s, this Longines stainless steel cylinder-design flyback chronograph is powered by the renowned Cal.13ZN and features a rare two-tone “unique” dial.
The scarce two-tone dial has an exceptionally distinctive layout: bar indexes at 12 and 6 o’clock, while the remaining positions feature roulette-style Arabic numerals. The combination of the two-tone coloration and the snail tachymeter scale further enhances the dial’s dense, intricate aesthetic and emphasizes the watch’s striking design character.
The beautifully executed cylinder case with elegant stepped lugs is non-waterproof, yet it retains the solid and substantial construction typical of Longines. It houses the celebrated Cal.13ZN movement—an exceptional chronograph caliber equipped with a standard flyback function. Among the many variations of vintage chronographs, this model undoubtedly ranks among the very finest examples.
Longines’ in-house chronograph calibers are masterpieces that have been firmly established in the history of watchmaking, and their reputation will undoubtedly continue to be recognized and appreciated for generations to come.
