Longines
Admiral
Hi-Beat / 1969


Intro

This 1969 Longines Ultra-Chron features a striking vertically brushed dial and a distinctive cushion-shaped case—elements that bring both depth and character to its vintage design. At its core is Longines’ high-beat movement, a testament to the brand’s dedication to precision during a pivotal era in watchmaking innovation. The watch is also equipped with a practical quick-set date function, adding to its everyday convenience. With its bold styling, mechanical sophistication, and historical relevance, this is a piece that any collector can appreciate—not only for its visual appeal, but for its place in the evolution of modern horology.

Intro

The Longines Ultra-Chron embodies everything one could hope for in a proper vintage dress watch. Introduced in the late 1960s and produced for only six years, it marked Longines’ bold attempt to bring high-precision mechanical timekeeping to a broader audience. Period advertisements promoted it as “the world’s most accurate watch... guaranteed accurate to within one minute per month.”

At the heart of this claim was the Caliber 431, a high-beat movement operating at 36,000 vibrations per hour—significantly enhancing timekeeping accuracy compared to standard movements of the time. Today, the Ultra-Chron stands as a lasting testament to Longines’ dedication to mechanical innovation and refined design during the golden era of Swiss watchmaking.
