It is the best witness to Longines pioneering position in the high-frequency field and a classic sought after by watch enthusiasts.
As early as 1910, Longines, symbolized by the flying hourglass, had already created the first high-frequency timing device that could accurately measure up to 1/10 of a second, laying a solid foundation for the development of high-frequency watches in the future. In 1959, Longines developed its first high-frequency movement for wristwatches, which was certified as an observatory watch and set a new record in accuracy, further consolidating the brand s leading advantage in high-frequency technology.
In 1968, Longines launched the Ultra Cron Diver watch, pioneering the combination of high-frequency movements and diving watches, becoming the industry s first diving watch to be equipped with a high-frequency movement, and writing an important page in the history of watchmaking. The all-new Longines ULTRA CHRON DIVER Super Observatory series L2.537.4.72.6 faithfully references the aesthetic design and professional diving function of the classic watch from 1968, perfectly blending retro charm with modern craftsmanship.
