Unworn Breitling Navitimer B19 Chronograph 43 Perpetual Calendar, Stainless Steel and Platinum, 43mm, Ref# PB1921251B1P1, box & papers

Introducing the unworn 2026 Breitling Navitimer B19 Chronograph 43 Perpetual Calendar, Ref# PB1921251B1P1—the most sophisticated expression of the iconic Navitimer, combining a high-performance chronograph with a perpetual calendar and moonphase complication. The 43mm stainless steel case is topped by a distinctive platinum bidirectional bezel incorporating Breitling’s iconic circular slide rule. Measuring just 14.94mm thick, the watch has a powerful yet refined presence, while the cambered sapphire crystal with double-sided anti-reflective treatment provides excellent clarity and protection. The anthracite dial gives the watch a deep, sophisticated character, complemented by a high-contrast slide-rule configuration and carefully balanced sub-dials. The complex layout displays the day, date, month, moonphase, and leap-year indication while preserving the unmistakable visual identity of the Navitimer. At the heart of this exceptional timepiece is the Breitling Manufacture Calibre B19, the brand’s first in-house perpetual-calendar chronograph movement. Comprising 374 components, it combines a chronograph with a sophisticated perpetual calendar and moonphase mechanism. The calendar automatically accounts for the different lengths of the months and leap years, with its indications advancing instantaneously at midnight. The self-winding B19 operates at 28,800 vibrations per hour and offers an impressive 96-hour power reserve. The chronograph measures elapsed time to 1/4 second with a 30-minute counter, while the movement is COSC-certified as a chronometer, confirming its high level of precision. The watch is presented on a brown alligator leather strap with a stainless steel folding clasp, providing a luxurious final addition to the sophisticated design. A screwed sapphire case back offers a view of the exceptional Manufacture movement. With 30-meter water resistance, the Navitimer B19 Chronograph 43 Perpetual Calendar represents the perfect fusion of Breitling’s aviation heritage and haute horlogerie craftsmanship—an exceptionally complex timepiece created for collectors who appreciate both iconic design and advanced mechanical watchmaking.
