B Navitimer B01 Chronograph 41 – Ref. AB0139241C2A1 (Stainless Steel Bracelet)

The B Navitimer B01 Chronograph 41 is a modern reinterpretation of a classic pilot’s watch, now presented in a sleek 41 mm case. This edition features a striking ice-blue sunburst dial paired with a polished stainless steel bracelet, combining aviation functionality with refined aesthetics.

Encased in brushed and polished stainless steel, it showcases a bidirectional notched bezel with the iconic Navitimer slide-rule, historically used for flight calculations. The dial presents three contrasting black chronograph subdials (elapsed seconds, 30 minutes, 12 hours) and a framed date at 6 o’clock. Baton indices and luminous hands ensure readability in all lighting conditions, while the red-tipped chronograph hand highlights its precision timing heritage.

At its heart beats the in-house Caliber B01 automatic chronograph, featuring 47 jewels, ~70 hours power reserve, and 28,800 vph. The sapphire caseback reveals the movement’s meticulous finishing and signature gold rotor (on select variants).

An integrated stainless steel bracelet adds comfort and elegance. The watch offers water resistance to 30 m, a gasket-sealed crown, and domed dual-sided anti-reflective sapphire crystal for durability and visual depth.
