Paying homage to three generations of inventors \u2013 L\u00e9on, Gaston & Willy Breitling \u2013 the Premier Duograph displays Breitling\u2019s watchmaking expertise with its split second complication. As Willy Breitling said, the Premier is an \u201cunmistakable stamp of impeccable taste\u201d.
This latest generation of Premier chronographs brings its timeless elegance back to life, and showcases Breitling\u2019s highest level of watchmaking thanks to a range of iconic Premier complications: the Chronograph, the Duograph and the Datora.
Featuring rectangular chronograph pushers, bi-compax chronograph look and Arabic numerals, the heritage-revived Premier chronographs display a variety of elegant design details such as grooves on the case-sides, open sapphire casebacks and vintage-inspired hands.
The Duograph comes in two variations: in stainless steel with a blue dial and a gold brown alligator strap or in 18k red gold with a black dial and a black alligator strap.
\u201cDuograph\u201d was a term used by Breitling in the 1940s and refers to a \u201cchronograph rattrapante”. A rattrapante (from the French \u201crattraper\u201d \u2013 to catch up) is one of the most elaborate of all watch complications. In terms of manufacturing difficulty, it\u2019s on a par with the tourbillon and minute repeater. Its function is to measure two elapsed times at once (intermediate and split time), which it shows via two hands on the central chronograph. The Duograph is powered by the manually wound cosc-certified Breitling Manufacture Caliber B15, featuring two patented innovations: one to simplify the mechanism and the other to improve accuracy.<\/p>\n","protected":false},"featured_media":119596,"template":"","meta":{"_acf_changed":false},"product_brand":[392],"product_cat":[491,493],"product_tag":[],"product_collection":[407],"class_list":["post-171940","product","type-product","status-publish","has-post-thumbnail","product_brand-breitling-en","product_cat-new","product_cat-watches","product_collection-premier-en","first","outofstock","shipping-taxable","purchasable","product-type-simple"],"acf":{"product_is_new":false,"product_not_available":false,"product_related_stores":null,"product_infos":"","product_features":[{"title":"Movement","description":"Caliber<\/b> : Breitling B15 (Manufacture)
