There have been many iterations of Breitling’s icon since its debut 70 years ago, but this new Navitimer captures its most classic features while enhancing them with modern refinements. A flattened slide rule and a domed crystal create the illusion of a sleeker profile. Alternating polished and brushed metal elements give a lustrous yet understated finish. And if there is one update sure to spark nostalgia, it's the return of the AOPA wings to their original position at 12 o’clock. This model features a dark green dial with black chronograph dials and a black leather strap. A transparent caseback reveals the chronometer-certified, high-performance, self-winding chronograph caliber, Manufacture Breitling Caliber 01. Case size: 46 mm. Case thickness: 14 mm. Water resistance: 30 m.
