Breitling reaffirms its supreme mastery of chronographs by unveiling its own split-seconds chronograph movement - one of the most sophisticated horological complications. Developed in the spirit of instruments for professionals, this Manufacture Breitling Caliber B03 (protected by two patents) is distinguished by its innovative construction ensuring a maximum of precision, sturdiness and reliability. To present this major technical breakthrough, Breitling has chosen its most emblematic model, the famous Navitimer, interpreted in steel or gold with an exclusive bronze-colored dial.
Few watch brands have their own mechanical chronograph movements. Fewer still also offer a proprietary split-seconds movement genuinely developed and produced in-house. With its two superimposed central chronograph hands, of which one can be stopped so as to measure an intermediate (split) time, before “catching up” (rattraper in French) with the first one still sweeping onwards, the split-seconds chronograph is considered one of the hardest watchmaking mechanisms to create. That is why this “Grand Complication” is generally produced in small series and requires watchmakers to perform a lengthy process of adjustment and rating (correcting the clearance of the split-seconds wheel and pinion, adapting the tension of the springs, adjusting the degree of penetration of the clamps, etc.).
