In the early 1940s, Willy Breitling envisioned a chronograph that combined functionality with sophistication. The Premier B01 Chronograph 42 embodies this vision, featuring vintage-inspired details like a smooth bezel, twin-register dial, and applied Arabic numerals. Available in various dial colors and materials, it comes with either an alligator leather strap or a sleek metal bracelet. Powered by the COSC-certified Breitling Manufacture Caliber 01, it offers 10 bars of water resistance, a 42 mm diameter, and an impressive 70-hour power reserve, making it a perfect blend of style and precision.
