Navitimer B03 Chronograph Rattrapante 45


The story

Available in steel or red gold versions, with an exclusive bronze-coloured dial, this Navitimer is powered by Manufacture Breitling Caliber B03 with split-seconds chronograph – one of the most sophisticated horological complications. Two patents have been filed for this innovatively built Breitling ‘engine’. The pushpiece housed in the 3 o’clock crown serves to stop and restart the split-seconds hand as many times as desired during a timing operation so as to measure intermediate (split) times. The ultimate mechanical chronograph in a legendary watch.
