Navitimer Heritage Stainless Steel / Black / Croco

The Navitimer was introduced in 1952 as a professional instrument for pilots, featuring a circular slide rule bezel that could calculate fuel consumption, climb and descent rates, and unit conversions — every calculation a pilot might need in the cockpit. It was adopted as the official watch of the Aircraft Owners and Pilots Association (AOPA), whose winged logo appeared on early dials. The Navitimer's defining characteristic is its dense, information-rich dial — a design that has never been simplified for the sake of contemporary fashion. It remains one of the longest continuously produced pilot's watches in history and Breitling's most recognisable model.

Breitling's bread & butter, tried & tested chronograph movement. Based on Valjoux / ETA 7750. Versions with both date as well as day & date exist; most of the B13 however only display the date.
