Product Details
Paying homage to three generations of inventors—Léon, Gaston, and Willy Breitling—the Premier collection embodies Breitling’s legacy as the inventor of the modern chronograph. As Willy Breitling put it, the Premier is the “unmistakable stamp of impeccable taste.” The modern Premier collection brings this history back to life while showcasing Breitling’s highest level of watchmaking. It comes with a range of complications: the Chronograph, the Duograph split-second, the Datora full calendar and the Tourbillon. The Premier Chronograph’s heritage-revived design features a variety of elegant design details, such as grooves on the case sides, rectangular pushers, applied Arabic numerals and vintage-inspired hands. It also features an open sapphire caseback that beautifully displays the manually wound COSC-certified Breitling Manufacture Caliber B09.
