Premier B15 Duograph 42

The Breitling Premier Heritage reference AB1510171C1P1 was introduced in 2021. This watch has a Stainless Steel case of 42.00mm, which holds a hand-wound caliber Caliber B15 movement with split-seconds chronograph. The dial is Blue. 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. “Duograph” was a term used by Breitling in the 1940s and refers to a “chronograph rattrapante". A rattrapante (from the French “rattraper” – to catch up) is one of the most elaborate of all watch complications. In terms of manufacturing difficulty, it’s on a par with the tourbillon and minute repeater.
