{"product_id":"l3-721-4-53-2","title":"Longines Spirit Pilot Flyback","description":"The LONGINES Spirit Pilot Flyback collection captures the brand’s persistent drive for innovation. This chronograph, with its flyback function, highlights LONGINES’ pioneering expertise in this field. The winged hourglass brand introduced its first flyback-equipped model in the early 1930s and secured a patent for the technology on June 16, 1936, marking a world-first achievement. Designed as a groundbreaking tool for pilots, the flyback complication makes it possible to time successive flight stages, greatly enhancing navigational efficiency. The precision of the LONGINES Spirit Pilot Flyback is powered by an exclusive Longines calibre, fitted with a silicon balance spring and resistant to magnetic fields. This hand-wound mechanical movement is officially certified as a chronometer by the COSC.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eCase\u003c\/b\u003e\u003cbr\u003eShape: Round\u003cbr\u003eMaterial: Stainless steel and ceramic bezel\u003cbr\u003eGlass: Scratch-resistant sapphire crystal, with several layers of anti-reflective coating on both sides\u003cbr\u003eCase Back: Screw-down and transparent with sapphire crystal case back\u003cbr\u003eDimension: Ø 39.50 mm\u003cbr\u003eLug distance: 20 mm\u003cbr\u003eLug-to-lug: 47.40 mm\u003cbr\u003eThickness: 13.40 mm\u003cbr\u003eWater Resistance: Water-resistant to 10 bar\u003cbr\u003eCase Specificities: Bi-directional rotating bezel\u003cbr\u003eWeight: 103.0 g\u003cbr\u003e\u003cbr\u003e\u003cb\u003eDial \u0026amp; Hands\u003c\/b\u003e\u003cbr\u003eDial color: Black matt\u003cbr\u003eHour markers: Applied Arabic numerals\u003cbr\u003eHands: Gilt hands\u003cbr\u003eSpecificities: Swiss Super-LumiNova®\u003cbr\u003e\u003cbr\u003e\u003cb\u003eMovement \u0026amp; Functions\u003c\/b\u003e\u003cbr\u003eMovement Type: Manual winding\u003cbr\u003eFunctions: Hours, minutes, small seconds at 9 o'clock\u003cbr\u003eCaliber: L792.4\u003cbr\u003eMovement Description: Mechanical movement with manual winding beating at 28'800 vibrations per hour, with a power reserve of approximately 68 hours\u003cbr\u003eChronograph: Flyback\u003cbr\u003eChronograph Functions: Chronograph mechanism: central 60 seconds hand and 30 minutes counter at 3 o'clock\u003cbr\u003e\u003cbr\u003e\u003cb\u003eStrap\u003c\/b\u003e\u003cbr\u003eUpper: Calf leather\u003cbr\u003eBack side: Calf leather\u003cbr\u003eColor: Brown\u003cbr\u003eBuckle: With double security folding clasp with micro adjustment system\u003cbr\u003eInterchangeability: Easily change your bracelet\/strap thanks to the Longines interchangeable system\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\u003eL3.721.4.53.2","brand":"Longines","offers":[{"title":"Default Title","offer_id":52888890376522,"sku":"L3.721.4.53.2","price":4400.0,"currency_code":"CHF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0838\/2060\/9866\/files\/mrKxZ9uWcMZUzn1mEp79_2F0_2F1d9ac36d76dbe7e68b304e387c614b68_48da381f-3eeb-4dc6-a78b-946de6620fc5.png?v=1777832621","url":"https:\/\/bijouterie-sonderegger.ch\/products\/l3-721-4-53-2","provider":"Sonderegger \u0026 Co.
