Description from the seller
An absolute masterpiece in the history of haute horology. We propose an extraordinary vintage Longines wrist chronograph equipped with the famed In-House Caliber 13ZN with Flyback function (return to flight), unanimously regarded by collectors and historians as one of the most fascinating, complex, and prestigious mechanical chronograph movements ever made.
The watch is accompanied by the official Longines Certificate of Authenticity / Archive Extract (issued in Saint-Imier in January 2023), attesting to its production and invoicing on February 22, 1941 at Ostersetzer, the historic and exclusive Longines authorized dealer/agent for Italy at the time.
