Housed in a 43mm round stainless steel case, the Navitimer B01 Chronograph 43 TWA Edition presents a silver dial featuring applied index hour markers with luminous-filled tips, a finely printed minutes, seconds, and fraction-of-a-second track, and red and white hands with luminous fill. A convex sapphire crystal glare-proofed on both sides protects the dial, while a transparent case back offers a view of the movement within. The date window sits between 4 and 5 o'clock, and the running seconds sub-dial is positioned at 9 o'clock.
Chronograph functions include a large central red seconds hand capable of measuring to one-quarter of a second, a 30-minute sub-dial counter at 3 o'clock, and a 12-hour counter at 6 o'clock. The stainless steel slide-rule bidirectional rotating bezel serves as a navigation computer, enabling airborne calculations such as fuel consumption, climb times, and unit conversions between miles, nautical miles, and kilometers. Powering the watch is the Breitling Caliber B01 automatic movement, COSC-certified, fitted with 47 jewels and offering a power reserve of approximately 70 hours.
The watch is presented on a brown calfskin leather strap secured by a tang buckle, with water resistance to 30 metres. This example is unworn with protective plastics removed at the authorized dealer, and is accompanied by the original Breitling papers and original Breitling watch box, along with the Breitling warranty.
