In 1968, Longines launched the Ultra-Chron Diver, the first dive 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 1\/10th of a second. 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 Ultra-Chron is inspired by the aesthetic codes and professional diving features of the 1968 model. These chronometer-certified watches are powered by an exclusive Longines calibre equipped with a silicon balance-spring and resistant to magnetic fields.<\/p>\n","protected":false},"featured_media":66046,"template":"","brand":[244,691],"class_list":["post-66056","watches","type-watches","status-publish","has-post-thumbnail","hentry","brand-longines-zh","brand-ultra-chron-zh"],"acf":[],"yoast_head":"\nLongines Ultra-Chron Classic L2.537.4.72.6 | Cortina Watch MY<\/title>\n<meta name=\"description\" content=\"High-frequency 36,000 vph automatic movement, chronometer-certified for precision.
