Breitling Navitimer B01 Chronograph 41

The Breitling Navitimer B01 Chronograph 41, reference AB0139A71G1P1, is a chronograph with a 41 mm steel case. The case measures 13.6 mm thick, with a lug width of 22 mm. A self-winding Breitling 01 movement drives the watch, offering approximately 70 hours of power reserve, and the cream dial sits below a cambered sapphire crystal treated on both sides. A date aperture and small seconds share the dial with the chronograph counters, and the sapphire display back shows the movement. Breitling fits the piece to a blue alligator leather strap with a folding steel clasp. The screwed-in caseback helps hold water resistance to 30 metres.
