The Navitimer 8 Chronograph 43 offers 30-minute and 12-hour counters at 12 and 6 o’clock, respectively, along with a small seconds hand at 9 o’clock. It is accurate to a quarter of a second. The COSC-certified Breitling Caliber 13 chronometer caliber is at the heart of this watch. It is wound automatically with the use of a unilateral ball-bearing rotor, delivering an autonomous running time of more than 42 hours. With a solid screwed caseback, the 43 mm case of the Navitimer 8 Chronograph 43 is available in steel with a leather strap or steel bracelet, or in DLC-coated steel paired with a leather strap.
