Breitling Navitimer 01 Chronograph 46mm – Ref. AB012721-BD09-441X-A20BA.1

Powerful, bold, and rooted in aviation heritage — the Breitling Navitimer 01 Chronograph 46mm is a timepiece built for those who demand precision and presence in equal measure. With its stainless steel 46mm case, this model makes an unmistakable statement on the wrist while honoring one of the most iconic pilot watches ever made.

The black dial with contrasting silver-tone chronograph subdials offers outstanding legibility, perfectly framed by the signature bi-directional slide rule bezel — a tool originally designed for in-flight calculations. A red central chronograph hand adds a dynamic touch, enhancing readability and emphasizing its technical prowess.

At the heart of this watch beats the Breitling Caliber B01, an in-house automatic movement with COSC certification, ensuring exceptional chronometric performance. With 47 jewels, a power reserve of approximately 70 hours, and advanced mechanisms like the column wheel and vertical clutch, this movement is built for endurance and precision.

Flipping the watch reveals the transparent sapphire caseback, proudly displaying the inner workings of this horological machine. Paired with a black alligator leather strap and folding clasp, the Navitimer balances luxury with practicality, allowing for all-day comfort and sophistication.

Despite its technical build, the watch retains elegance, with a case thickness of 14.5mm and water resistance up to 30 meters, suitable for daily wear or travel.
