Longines - Chronograph Flyback Years 30s – Calibre 13ZN - 5454312 - Men - 1936

Very rare Longines chronograph from 1936 (36 mm diameter excluding crown), an extraordinary example from the golden era of watchmaking.

This piece stands out for its perfect contemporaneity and absolute historical integrity: serial number 5454312 is stamped both inside the Staybrite steel case back and engraved directly on the movement bridges. This unique correspondence certifies its birth and the originality of every component.

The watch is powered by the legendary manufacture caliber 13ZN with column-wheel chronograph operation (17 jewels, 18,000 A/h), a manually wound movement revered by collectors for its superb technical architecture.

The Snap-On Mobile LugsThe true distinctive element of the three-piece case is represented by its fascinating stainless steel movable lugs.
The lugs are hinged to the case by a screw pin and feature a geometrically angular design that softens and adapts to the curvature of the wrist.
This vintage solution, born to ensure ergonomics before the spread of fixed lugs, gives the timepiece a unique vintage character.

The original dial shows a beautiful patina that attests to its authenticity.
The configuration is a classic bicompax with counters decorated with concentric circles (azurage) and blued steel feuille hands with a bluish sheen.
The refined triple scale stands out: inner minute scale at 1/5 of a second in black, central red telemeter scale, and outer blue tachymeter scale.

The case features a two-step bezel, rectangular pushers, and a fluted crown.
The movement is perfectly functional (start, stop and reset operate normally).
It is completed by a leather strap and generic buckle, and is housed in a splendid original Longines box, not period to the reference but contemporaneous to the brand.
