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.\u003c\/p\u003e","brand":"Swatch Group U.S.","offers":[{"title":"Default Title","offer_id":45155879125174,"sku":"596-120097","price":4000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0699\/2140\/7158\/files\/c558305a-caaf-4c50-b6b6-63065d481afe_24kmbr_24Screenshot_202026-06-01_20151533.png?v=1780350660","url":"https:\/\/www.jacklewisjewelers.com\/products\/longines-ultra-chon-classic-37mm-watch-with-sunray-silver-dial","provider":"Jack Lewis Jewelers","version":"1.0","type":"link"}
