The reference AB0138241C1A1 belongs to the Breitling Navitimer B01 Chronograph 43 line.
The Navitimer story goes back to 1952, when Willy Breitling created a chronograph with a circular slide rule so pilots could perform flight calculations directly on the wrist. Two years later it became the official watch of the Aircraft Owners and Pilots Association (AOPA), turning it into one of the most recognizable aviation watches ever made. 
Modern references like AB0138241C1A1 keep that same pilot-instrument DNA but update it with Breitling’s in-house B01 chronograph movement and contemporary design details.
