Overview
This is a vintage Longines Ultra-Chron automatic wristwatch featuring a 10k gold-filled monocoque case and a silvered dial with applied indices. It represents a landmark moment in watchmaking history when brands raced to create ultra-high-frequency movements to combat the rising threat of quartz technology.
Story
Introduced in 1967 to celebrate Longines' centenary, the Ultra-Chron was advertised as the world's most accurate watch. Its high-beat heart hummed at a blistering 36,000 vibrations per hour, guaranteeing accuracy to within a minute a month.
Maker / Origin
Founded in 1832 by Auguste Agassiz, Longines is one of Switzerland's oldest and most respected watchmakers, famous for its pioneering aviation instruments and sports timing. During the mid-20th century, they were an absolute powerhouse of in-house movement design, pushing the boundaries of mechanical precision before the quartz crisis reshaped the industry.
Condition & Value
The watch shows moderate cosmetic wear consistent with age, including light scratching on the acrylic crystal and caseback. The original strap has been replaced with a vintage Speidel metal expansion band.
