n 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 1/10’" 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). Its instantly recognizable 43mm cushion-shaped steel case is fitted with a diving bezel that boasts a sapphire insert with luminescent accents. The eye-catching black grained dial features a white minute track with alternating Super-LumiNova-coated batons and rhodium plated appliques.

The original Ultra-Chron logo is proudly applied on the dial and embossed on the caseback. The new Longines Ultra-Chron has a distinctive red minute hand which, like the hour hand, is coated with Super-LumiNova for optimal legibility.
