At the time, LONGINES had already established itself as a pioneer in high-frequency technology. As early as 1914, 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.\u003c\/p\u003e","brand":"Longines","offers":[{"title":"Default Title","offer_id":47203722264747,"sku":"L2.839.4.52.2","price":5550.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/2783\/3515\/files\/4718161744.jpg?v=1780855353","url":"https:\/\/www.exquisitetimepieces.com\/products\/longines-l2-839-4-52-2-ultra-chron-carbon","provider":"Exquisite Timepieces","version":"1.0","type":"link"}
