{"product_id":"pb1920251c1a1","title":"Navitimer B19 Chronograph 43 Perpetual Calendar","description":"For our 140th anniversary, we introduced the Caliber B19—Breitling’s first exclusive perpetual calendar chronograph movement. The milestone achievement now powers this special-edition Navitimer, a watch with its own legendary history.\u003cbr\u003eFirst created in 1952 for the Aircraft Owners and Pilots Association (AOPA), the Navitimer was designed for precision in the cockpit, combining a chronograph with Breitling’s patented circular slide rule. Pilots swore by its flight-computer functionality, but its appeal soon extended beyond aviation—to star athletes, musicians, and even astronauts. In 1962, it became the first Swiss wristwatch in space.\u003cbr\u003eThis edition bridges past and future: a steel case, platinum bezel, ice-blue dial, and the remarkable B19 movement—an automatic chronograph with a perpetual calendar. A watch built from heritage, made for today.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eMovement\u003c\/b\u003e\u003cbr\u003eCaliber: Breitling B19 (Manufacture)\u003cbr\u003eMovement: Self-winding mechanical\u003cbr\u003ePower Reserve: Approx. 96 hours\u003cbr\u003eChronograph: 1\/4 second, 30 minutes\u003cbr\u003eVibration: 28,800 v.p.h\u003cbr\u003eJewel: 39 jewels\u003cbr\u003eCalendar: Perpetual calendar with moon-phase\u003cbr\u003e\u003cbr\u003e\u003cb\u003eCase\u003c\/b\u003e\u003cbr\u003eCase Material: Stainless steel \u0026amp; platinum\u003cbr\u003eCaseback: Screwed in (sapphire crystal)\u003cbr\u003eWater Resistance: 3 bars (30 m \/99 ft)\u003cbr\u003eBezel: Bidirectional, slide rule\u003cbr\u003eCrown: Non screw-locked, two gaskets\u003cbr\u003eCrystal: Cambered sapphire, glareproofed both sides\u003cbr\u003e\u003cbr\u003e\u003cb\u003eDimensions\u003c\/b\u003e\u003cbr\u003eDiameter: 43 mm\u003cbr\u003eThickness: 14.94 mm\u003cbr\u003eLug Width (in-between lugs): 22.05 mm\u003cbr\u003e\u003cbr\u003e\u003cb\u003eStrap\u003c\/b\u003e\u003cbr\u003eStrap Material: Stainless steel\u003cbr\u003eStrap Colour: Metal bracelet\u003cbr\u003eStrap Type: Straight\u003cbr\u003eLug: 22\/18 mm\u003cbr\u003e\u003cbr\u003e\u003cb\u003eReference\u003c\/b\u003e\u003cbr\u003ePB1920251C1A1","brand":"Breitling","offers":[{"title":"Default Title","offer_id":55143698432378,"sku":"PB1920251C1A1","price":29500.0,"currency_code":"CHF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0271\/1158\/7928\/files\/hBsbNEH0uyVkrLyOVtHN_2F0_2F9ae2e21e3dc31a43e02e563b241c9937_b354f51c-eb98-4df2-9ffc-deffa3d55dfb.png?v=1787249729","url":"https:\/\/www.michaud.ch\/en\/products\/pb1920251c1a1","provider":"Michaud SA","version":"1.0","type":"link"}
