Longines Ultra-Chron

Longines is launching a new model that is more accurate than a chronometer: The new LONGINES ULTRA-CHRON, ticking at 10 beats a second. The new high-frequency movement guarantees higher precision and profits from Longines’ rich heritage of producing high-beat movements for over 100 years. Inspired by the original Longines Ultra-Chron Diver of 1968, the new model reflects the iconic design codes of its ancestor and is highly resistant to shocks, scratches and water pressure.

In 1968, Longines launched the Ultra-Chron Diver, the first dive watch to be equipped with a high-frequency movement. At the time, Longines had already established itself as a pioneer in high-frequency technology. In fact, the winged hourglass brand created its first high-frequency timekeeping device to measure precisely 1/10th of a second as early as in 1914. In 1959, Longines developed the first high-beat movement for a wristwatch, an observatory chronometer that set new records in terms of accuracy.

The new Longines Ultra-Chron is inspired by the aesthetic codes as well as the professional dive features of the 1968 model. It features a unidirectional rotating bezel as well as a screwed-in caseback and crown. It also offers great legibility and is water resistant to 30 bar (300 meters).
