The Breitling Navitimer 8 Chronograph made its debut in 2018 alongside the Navitimer 8 collection. It boasts a sleek stainless steel case measuring 43*14.17mm and houses the impressive self-winding caliber B13 (Valjoux 7750). Last year, the A13314101 model was replaced by the new and improved A13316101, now known as the Aviator 8. This update includes a revamp of the bezel, which now displays 12-hour markings.
