Ultra-chron
L2.836.4.52.6
In 1968, LONGINES launched the Ultra-Chron Diver, the first diver's watch equipped with a high-frequency movement. At the time, LONGINES had already established itself as a pioneer in high-frequency technology. As early as 1910, the winged hourglass brand created the first high-frequency timekeeping device capable of measuring tenths of a second. In 1959, LONGINES developed the first high-frequency movement for a wristwatch, an observatory chronometer that set new precision records. The new Ultra-Chron is inspired by the aesthetic codes and professional diving functions of the 1968 model. These chronometer-certified watches are powered by an exclusive LONGINES caliber, equipped with a silicon balance-spring and resistant to magnetic fields.
