{"product_id":"ultra-chron-box-edition","title":"ULTRA‑CHRON CARBON","description":"\u003cp\u003e\u003cspan\u003eIn 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.\u003c\/span\u003e\u003c\/p\u003e","brand":"Longines","offers":[{"title":"Default Title","offer_id":48824842387706,"sku":"L2.839.4.52.2","price":7250.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0695\/4909\/7210\/files\/Untitled_4921c124-b603-4346-9664-c88ea1b895e7.png?v=1777750337","url":"https:\/\/checkout.chateaudivoire.com\/en\/products\/ultra-chron-box-edition","provider":"Château D'Ivoire","version":"1.0","type":"link"}
