Breitling Navitimer B01 Chronograph 43 – Ref. AB0138241G1P1 (Leather Strap)
Few timepieces embody heritage and innovation as seamlessly as the Breitling Navitimer B01 Chronograph 43. In the Ref. AB0138241G1P1, Breitling revives one of its most iconic aviation designs — with refined details that speak to today’s discerning collector.
Its 43mm stainless steel case surrounds a clean silver dial offset by bold black chronograph subdials, delivering the coveted “reverse panda” aesthetic. The red-tipped central chronograph hand adds a modern pulse to this classically inspired dial, while the signature circular slide rule bezel stays true to its pilot watch origins.
Beneath the surface beats the high-performance Breitling Manufacture Caliber B01 — an in-house, COSC-certified movement boasting a 70-hour power reserve, column wheel, and vertical clutch. This engine ensures exceptional chronograph accuracy and long-term reliability.
A black alligator leather strap with a folding clasp gives the watch an elevated presence, comfortable enough for daily wear yet elegant enough for any occasion. Turn it over and admire the exhibition sapphire caseback, offering a clear view of the movement’s fine finishing and engraved rotor.
