1940s Longines Cal.13zn "Tre-tacche" Step bezel Water-resistant Two-tone multi-scaled dial with Archives

A very rare Longines chronograph manufactured in the early 1940s, featuring the legendary Cal. 13zn movement, with a "Tretake" 37.5mm step design screw-back waterproof case and a silver two-tone multi-scale dial. The step design and three-point screw-back waterproof case, from which the "Tretake" gets its name, are characteristic of Longines' substantial construction. The oversized 37mm case housing the Cal. 13zn exhibits an overwhelming presence, making this a precious piece. The dial design is also exceptional, featuring a silver two-tone base with a tachymeter (black) and a telemeter (blue) in a multi-scale design, which is rare for Longines, known for simpler designs. The beautiful patina adds a wonderful vintage charm. Longines' in-house caliber chronographs are firmly established masterpieces in watch history, and they are expected to continue to be highly regarded and cherished in the future.
