Navitimer B01 Chronograph 43 Tribute to Concorde Limited Edition

From the retailer listing

Paying tribute to the height of the Jet Age The Concorde was created at the height of the jet age, a period of rapid aeronautical innovation. It redefined what was possible in the sky, cutting trans-Atlantic flight times in half at twice the speed of sound and lifting passengers high enough to glimpse the curvature of the Earth. The supersonic aircraft was a symbol of a time when the world dreamed bigger. The Breitling Navitimer B01 Chronograph 43 Tribute to Concorde is expressed through a blue dial inspired by the shade of the stratosphere as seen from the plane, paired with a matching alligator strap. Contrasting white subdials and an inner slide rule reference Concorde’s nickname White Bird (“L’Oiseau Blanc”). Limited to 593 pieces, a reference to the Olympus 593 turbojet engines that powered the aircraft. The caseback is engraved with “One of 593,” “Tribute to Concorde,” “Jetliner,”
