The partnership between Breitling and Aston Martin Aramco Formula One™ Team comes to life in a Navitimer conceived for a world where milliseconds matter. Limited to 1,959 pieces, the Navitimer B01 Chronograph 43 Aston Martin Aramco Formula One™ Team marks the year Aston Martin entered Formula 1. It brings together race-driven materials, precision engineering, and over 70 years of Navitimer heritage. From its carbon-fiber dial and lightweight titanium case to details inspired by the cockpit of an F1 car, every element is designed for absolute timing accuracy under pressure. Turning the watch over reveals its engine, the Breitling Manufacture Caliber 01, fitted with a specially developed matte-black rotor bearing the Aston Martin Aramco logo. Originally developed as a pilot’s instrument, with a circular slide rule for real-time calculations, the Navitimer made its way from sky to circuit, worn by drivers who demanded the same precision on the track.
