Product Details
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 infinitley wearable - in his words, "the unmistakable stamp of impeccable taste." He called this new line the Premier.
To create its modern Breitling Premier B01 Chronograph 42, Breitling preserved distinctive vintage-Premier details, including the smooth fixed bezel, twin-register dial, streamlined rectangular pushers and applied Arabic numeralds. It comes on a choice of classic alligator leather strap or a 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 Manufcature Caliber 01 - designed for maximum precision, reliability and functionality.
