Longines - Engineer Chronograph Cal. 13ZN - Men - 1941

Rare Longines Chronograph "Engineer" – Calibre 13ZN (1941)

This magnificent piece from the early 1940s is a true milestone in watchmaking. Its beating heart is the legendary Calibre 13ZN, introduced by Longines in 1936 and universally recognized by collectors as one of the most important, beautiful, and innovative chronograph movements ever made. Renowned for its superb manufacture architecture, the 13ZN represents a piece of history on the wrist. The movement serial number (6117***) perfectly matches the interior case reference, dating the watch to 1941 and confirming its absolute originality "matching numbers" in every part, a crucial detail that exponentially increases its rarity and desirability.
