In the early 1940s, Willy Breitling envisioned a post-war chronograph that combined functionality with elegance, leading to the creation of the Premier. The modern Premier B01 Chronograph 42 retains classic features like the smooth bezel, twin-register dial, and applied Arabic numerals, and is offered in various dial colors and case materials. It can be paired with an alligator leather strap or a sleek 7-row metal bracelet. Powered by the COSC-certified Breitling Manufacture Caliber 01, it meets Willy Breitling's high standards for precision and reliability.
