A rattrapante (from the French “rattraper” – to catch up) is one of the most elaborate of all watch complications. In terms of manufacturing difficulty, it’s on a par with the tourbillon and minute repeater. Its function is to measure two elapsed times at once (intermediate and split time), which it shows via two hands on the central chronograph. The Duograph is powered by the manually wound cosc-certified Breitling Manufacture Caliber B15, featuring two patented innovations: one to simplify the mechanism and the other to improve accuracy.\u003c\/p\u003e","brand":"Breitling","offers":[{"title":"Default Title","offer_id":56237025689922,"sku":"15078","price":399.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0992\/6370\/9506\/files\/breitling-premier-b15-duograph-42-stainless-steel-ref-ab1510171c1p1-uordh.jpg?v=1790135825","url":"https:\/\/watchsupply88.com\/products\/breitling-premier-b15-duograph-42-stainless-steel-ref-ab1510171c1p1-5154","provider":"Watch Supply 88","version":"1.0","type":"link"}
