Baselworld 2017: Breitling Navitimer Rattrapante Calibre B03
With its two superimposed central chronograph hands, of which one can be stopped, by pushing the push-piece being integrated in the crown, so as to measure an intermediate (split) time, before “catching up” (= rattraper in French), by again pushing the push-piece being integrated in the crown, with the first one still sweeping onwards, the split-seconds chronograph is considered one of the most sophisticated watchmaking mechanisms to create.
