Line: ULTRA-CHRON
In 1968, Longines launched the Ultra-Chron Diver, the first diving watch equipped with a high-frequency movement.
By that time, Longines had already established itself as a pioneer of high-frequency technology.
As early as 1910, the winged hourglass brand created the first high-frequency timing device capable of measuring 1/10th of a second.
In 1959, Longines developed the first high-frequency movement.
