Caliber B15

A hand-wound split-seconds chronograph drawn from Breitling's in-house B01 architecture. Duograph is the name Breitling used in the 1940s for a rattrapante: two chronograph hands run together until one is stopped to read a split time, then catches the other up. It is chronometer-certified, and the mechanism carries two patents Breitling took out to simplify it and sharpen its accuracy.
