Breitling Watch Premier B01 Chronograph 42 AB0145371L1P1. In the early 1940s, Willy Breitling was already dreaming of a time after the war, when utility would give way to unbridled optimism. He began designing a chronograph that would be functional but also undeniably elegant and infinitely wearable—in his words, “the unmistakable stamp of impeccable taste.” He called this new line the Premier. To create its modern Premier, Breitling preserved distinctive vintage-Premier details, including the smooth fixed bezel, twin-register dial, streamlined rectangular pushers and applied Arabic numerals. The Premier B01 Chronograph 42 is available in an array of dial colors and case materials. It comes on a choice of classic alligator leather strap or sleek 7-row metal bracelet. Today’s Premier also lives up to Willy Breitling’s uncompromising technical standards with its exceptional self-winding movement—the COSC-certified Breitling Manufacture Caliber 01—designed for maximum precision, reliability and functionality.
