Calibre Longines 431 - Circa 1970



The story of Longines Ultra-Chron watches begins at the end of the 1960’s. Their objective? To rub shoulders with Girard-Perregaux and Seiko, which have only very recently offered watches whose heart beats rapidly. Indeed, the movement of this Longines Ultra-Chron beats at a frequency of 36,000 vibrations per hour. A real revolution for the time, resulting in desired chronometric precision. The Longines advertisements of the time hence shouted loud and clear for the “most precise watch in the world.”
