Description
In 1968, LONGINES introduced the Ultra-Chron Diver, the first dive watch featuring a high-frequency movement. Building on a legacy of precision, LONGINES had pioneered high-frequency timekeeping since 1910 with a device measuring 1/10th of a second. In 1959, the brand crafted the first high-beat wristwatch movement, setting new standards in accuracy. The modern Ultra-Chron pays homage to the 1968 design and professional diving functions. These chronometer-certified timepieces house a unique LONGINES calibre with a silicon balance spring, offering enhanced magnetic resistance and reliability.
