Product Description
Paying homage to three generations of inventors – Léon, Gaston & Willy Breitling – the Premier Chronograph embodies Breitling’s legacy of inventing the modern Chronograph. As Willy Breitling said, the Premier is an “unmistakable stamp of impeccable taste”.
This latest generation of Breitling Premier chronographs brings its timeless elegance back to life, and showcases Breitling’s highest level of watchmaking thanks to a range of iconic Breitling Premier complications: the Chronograph, the Duograph and the Datora. Featuring rectangular chronograph pushers, bi-compax chronograph look and Arabic numerals, the heritage-revived Breitling Premier chronographs display a variety of elegant design details such as grooves on the case-sides, open sapphire casebacks and vintage-inspired hands. The Breitling Premier Chronograph comes in two variations: in stainless steel with a pistachio green dial and a gold brown alligator strap or in 18k red gold with a silver dial and a brown alligator strap. The Chronograph is powered by the manually wound cosc-certified Breitling Manufacture Caliber B09.
