Breitling Super AVI B04 Chronograph GMT 46 P-51 Mustang

The Breitling Super AVI B04 Chronograph GMT 46 P-51 Mustang, reference AB04453A1B1X1, is a chronograph in a 46 mm steel case. Thickness runs to 15.9 mm, with a lug width of 24 mm. A cambered sapphire crystal, glareproofed on both sides, covers the black dial. Inside is the self-winding Breitling Manufacture calibre B04, a chronometer-certified movement with 70 hours of power reserve. Alongside the chronograph function, the watch adds a GMT complication for tracking a second time zone, plus a date aperture and small seconds. The crown is screw-locked with two gaskets, in keeping with the watch's cockpit-instrument character. A calfskin leather strap closes on a steel folding clasp, and the screw-down crown helps keep the case rated to 100 metres.
