{"product_id":"longines-ultra-chron","title":"LONGINES ULTRA-CHRON 43mm + Sapphire Automatic","description":"\u003cp\u003eIn 1968, LONGINES launched the Ultra-Chron Diver, the first diving watch equipped with a high-frequency movement. At that 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 timing device capable of measuring hundredths of a second. In 1959, LONGINES developed the first high-frequency movement for a wristwatch, an observatory chronometer that set new precision records. The new Ultra-Chron draws inspiration from the aesthetic codes and professional diving watch features of the 1968 model. These chronometer-certified watches are powered by an exclusive LONGINES caliber, featuring a silicon balance spring and resistance to magnetic fields.\u003c\/p\u003e","brand":"Longines","offers":[{"title":"Default Title","offer_id":44853198586045,"sku":"L28364526","price":3900.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0652\/0596\/0893\/files\/LONGINES_0000_L2.836.4.52.6_SOL.jpg?v=1739817916","url":"https:\/\/blissjewelers.com\/products\/longines-ultra-chron","provider":"Bliss Jewelers","version":"1.0","type":"link"}
