Longines 30ch Chronograph Big Eye Ref. 7981-1

Introduced in the late 1940s, the Longines 30CH movement marked a defining moment in chronograph evolution — a direct successor to the legendary 13ZN and one of the finest manually wound column-wheel calibers ever produced. Celebrated for its precision, reliability, and smooth operation, the 30CH powered some of Longines’ most iconic sporting chronographs throughout the mid-20th century.

This exceptional example, the Longines 30CH Ref. 7981-1 “Big Eye” from 1966 (SN 13.xxx.xxx), showcases one of the most charismatic and collectible configurations of the series. It features the bold black dial with contrasting white “Big Eye” sub-counters, designed for optimal readability and distinctive visual balance, framed by the rare and vibrant red bezel and pump pushers that complete its unmistakable character.

The care remains incredibly sharp, retaining crisp edges and original proportions, while the dial is flawless, exhibiting perfect contrast and patina-free surfaces. Every detail reflects the care of a timepiece that has been exceptionally preserved over nearly six decades.

Fitted with a Swiss Tropic black strap, it exudes an authentic vintage sport aesthetic, while the heart of the 30CH beats with remarkable precision. Fully lab-checked and performing flawlessly, this chronograph stands as a true collector’s piece — a rare blend of technical mastery, design purity, and preserved originality that embodies the golden age of Longines watchmaking.
