Premier B25 Datora 42

Paying homage to three generations of inventors – Léon, Gaston & Willy Breitling – the Premier Datora is the most refined Breitling chronograph with its complete calendar and moon-phase. As Willy Breitling said, the Premier is an “unmistakable stamp of impeccable taste”.
This latest generation of Premier chronographs brings its timeless elegance back to life, and showcases Breitling’s highest level of watchmaking thanks to a range of iconic Premier complications: the Chronograph, the Duograph and the Datora.
Featuring rectangular chronograph pushers and Arabic numerals, the heritage-revived Premier Datora displays a variety of elegant design details such as grooves on the case-sides, open sapphire casebacks and vintage-inspired hands.
The Datora comes in two variations: in stainless steel with a copper dial and a brown alligator strap or in 18k red gold with a silver dial and a brown alligator strap. “Datora” was a term used by Breitling in the 1940s and refers to a complete calendar chronograph displaying day, date, month and the different moon phases. The Datora is powered by the cosc-certified Manufacture Caliber B25.
