This timepiece is a magnificent artifact from 1971, as confirmed by the archival reference 16063469 often seen in this specific production run. The reference 4-50379 is defined by its substantial stainless steel cushion case and the iconic applied five-star emblem on the dial, a mark that historically signaled Longines' highest-grade automatic movements. It is powered by the legendary Caliber 505, a 17-jewel mechanical masterpiece based on the high-performance Record designs of the era, engineered to provide uncompromising accuracy and a specialized "push-crown" quickset date function for the modern professional.

The architecture is quintessentially retro-executive, utilizing a heavy steel case with sharp factory brushing and a breathtaking silvered sunray dial that exemplifies the era's sophisticated aesthetic. The dial is a work of high-end Swiss art, featuring hand-applied faceted indices and the famous Winged Hourglass logo. Flipping the watch over reveals the solid stainless steel caseback, which protects the high-frequency mechanical heart beating at 19,800 vibrations per hour. This is an essential acquisition for an elite collector who appreciates 1970s industrial luxury, the mechanical soul of a Five-Star heart, and the bold, shimmering presence of a vintage Longines Admiral.
