Longines 7413 Jumbo Flyback Chronograph 1972

Longines Flyback Chronograph Ref. 7413 – Legendary Caliber 30CH (1972)

When it comes to vintage chronograph movements, few names command as much respect as Longines and the legendary Caliber 30CH. Revered by collectors for its precision, construction, and beautifully smooth operation, the 30CH stands among the great chronograph calibers ever produced.

Its predecessor, the famous Longines 13ZN, is often considered one of the finest chronograph movements ever designed. Introduced in 1947, the 30CH carried over the same celebrated architecture and retained the highly desirable flyback function, allowing the chronograph to be instantly reset and restarted with a single push — a feature originally developed for professional timing applications.

This particular example, Ref. 7413, elevates the technical brilliance of the movement with an huge 38 mm stainless steel case and a beautifully preserved silver sunburst dial. The balanced proportions, clean dial layout, and warm gold tones create a chronograph that feels both sophisticated and purposeful.

Preserved in outstanding condition and accompanied by its original Longines certificate from 1972 Valencia, Spain, this watch is a rare opportunity to own one of the most respected vintage flyback chronographs ever made.

A true collector’s piece — combining technical excellence, timeless design, and Longines’ golden-era chronograph heritage.
