The Chronomat B01 42 is Breitling's in-house automatic chronograph, built around the Caliber B01 movement with a 70-hour power reserve and a column-wheel, vertical-clutch chronograph. This version pairs a blue dial with a blue rubber strap and a stainless steel case rated to 200 m, with a unidirectional bezel, tachymeter scale, date and luminous hands and markers. It suits buyers who want a sporty, water-ready chronograph with genuine manufacture movement rather than a modular third-party caliber. Against rivals like the Omega Speedmaster or TAG Heuer Carrera, it stands out for its 200 m rating and long power reserve, while being thicker and heavier on the wrist.
