{"product_id":"l2-937-4-72-2","title":"Ultra-chron Classic","description":"In 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.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eCase\u003c\/b\u003e\u003cbr\u003eShape: Round\u003cbr\u003eMaterial: Stainless steel\u003cbr\u003eGlass: Scratch-resistant sapphire crystal, with several layers of anti-reflective coating on both sides\u003cbr\u003eDimension: Ø 40.00 mm\u003cbr\u003eLug distance: 21 mm\u003cbr\u003eLug-to-lug: 47.20 mm\u003cbr\u003eThickness: 10.95 mm\u003cbr\u003eWater Resistance: Water-resistant to 5 bar\u003cbr\u003eWeight: 68.0 g\u003cbr\u003e\u003cbr\u003e\u003cb\u003eDial \u0026amp; Hands\u003c\/b\u003e\u003cbr\u003eDial color: Sunray silver\u003cbr\u003eHour markers: Applied indexes\u003cbr\u003eHands: Silvered polished hands\u003cbr\u003e\u003cbr\u003e\u003cb\u003eMovement \u0026amp; Functions\u003c\/b\u003e\u003cbr\u003eMovement Type: Automatic\u003cbr\u003eFunctions: Hours, minutes, seconds and date\u003cbr\u003eCaliber: L836.6\u003cbr\u003eMovement Description: Self winding mechanical movement beating at 36'000 vibrations per hour, with a monocrystalline silicon balance-spring power reserve up to 52 hours\u003cbr\u003e\u003cbr\u003e\u003cb\u003eStrap\u003c\/b\u003e\u003cbr\u003eUpper: Alligator leather\u003cbr\u003eBack side: Calf leather\u003cbr\u003eColor: Black\u003cbr\u003eBuckle: With buckle\u003cbr\u003e\u003cbr\u003e\u003cb\u003eGeneral\u003c\/b\u003e\u003cbr\u003eMagnetic resistant: Yes\u003cbr\u003eChronometer Officially Certified: Yes\u003cbr\u003e\u003cbr\u003e\u003cb\u003eGeneral\u003c\/b\u003e\u003cbr\u003eMagnetic resistant: Yes\u003cbr\u003eChronometer Officially Certified: Yes\u003cbr\u003e\u003cbr\u003e\u003cb\u003eGeneral\u003c\/b\u003e\u003cbr\u003eMagnetic resistant: Yes\u003cbr\u003eChronometer Officially Certified: Yes\u003cbr\u003e\u003cbr\u003e\u003cb\u003eGeneral\u003c\/b\u003e\u003cbr\u003eMagnetic resistant: Yes\u003cbr\u003eChronometer Officially Certified: Yes\u003cbr\u003e\u003cbr\u003e\u003cb\u003eGeneral\u003c\/b\u003e\u003cbr\u003eMagnetic resistant: Yes\u003cbr\u003eChronometer Officially Certified: Yes\u003cbr\u003e\u003cbr\u003e\u003cb\u003eGeneral\u003c\/b\u003e\u003cbr\u003eMagnetic resistant: Yes\u003cbr\u003eChronometer Officially Certified: Yes\u003cbr\u003e\u003cbr\u003e\u003cb\u003eGeneral\u003c\/b\u003e\u003cbr\u003eMagnetic resistant: Yes\u003cbr\u003eChronometer Officially Certified: Yes\u003cbr\u003e\u003cbr\u003e\u003cb\u003eReference\u003c\/b\u003e\u003cbr\u003eL2.937.4.72.2","brand":"Longines","offers":[{"title":"Default Title","offer_id":52888907022666,"sku":"L2.937.4.72.2","price":3200.0,"currency_code":"CHF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0838\/2060\/9866\/files\/JdaBST2omduH1BdP5szL_2F0_2Fc5a7a968045bb29615633d28a0c4f755_23f2d2d1-7568-4cce-bdce-d86f3505ae96.png?v=1779387764","url":"https:\/\/bijouterie-sonderegger.ch\/products\/l2-937-4-72-2","provider":"Sonderegger \u0026 Co.
