History The Breitling Chronomat reference 769 was introduced in the early 1940s and represents a major development in scientific chronographs, debuting the rotating slide rule bezel that would later define the brand's aviation aesthetic. During the mid-twentieth century, Swiss manufacturers frequently partnered with established United States importers to navigate complex trade regulations and tariffs. Welsbro Watch Co, a New York-based importer, was one such entity. It was not uncommon for imported Swiss watches to feature mixed branding, with cases and movements stamped by the importer to satisfy customs requirements while retaining the original manufacturer dial. These transatlantic configurations provide a compelling glimpse into the era's specialized distribution networks and remain highly sought-after by dedicated collectors today. / Second Vintage SKU: BRE-BCX-0001
