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\/span\u003e\u003c\/p\u003e","brand":"Longines","offers":[{"title":"Default Title","offer_id":47087348187380,"sku":"WGLON18358","price":4000.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0416\/5874\/4986\/files\/longines-ultra-chron-classic-40mm-l29374726-4471965.jpg?v=1761618298","url":"https:\/\/chpremier.com\/products\/longines-ultra-chron-classic-40mm-l29374726","provider":"CH Premier Jewelers","version":"1.0","type":"link"}
