This stunning Premier B01 Chronograph features a 42 mm stainless steel case. Its striking blue dial is highlighted by contrasting black 1/4th second, 30-minute, and 12-hour chronograph counters that indicate the Manufacture mechanical movement inside. A transparent sapphire caseback reveals its self-winding high-performance chronometer-certified chronograph caliber, the Manufacture Breitling Caliber 01, which is delivered with a five-year warranty. The Premier B01 Chronograph is available with a seven-row stainless steel bracelet, a crocodile leather strap, or a nubuck leather strap. Elegance and performance worthy of the Breitling Premier name.
