Breitling Navitimer B01 Chronograph Watch

The Breitling Navitimer B01 Chronograph is one of the most iconic pilot's watches ever made — a masterclass in aviation heritage and mechanical precision. First introduced in 1952, the Navitimer has graced the wrists of pilots, collectors, and connoisseurs for over seven decades, and this modern iteration elevates that legacy with Breitling's in-house Calibre B01 movement.

Movement

Powered by the Breitling Calibre B01 — a COSC-certified chronometer movement developed and manufactured entirely in-house. Beating at 28,800 vph (4 Hz) with a generous 70-hour power reserve, the B01 offers exceptional accuracy and reliability. The column-wheel chronograph mechanism and vertical clutch ensure smooth, precise start/stop operation.

Case & Dial

The distinctive 41mm or 43mm stainless steel case houses the iconic bi-directional slide rule bezel — a functional tool originally designed for airspeed, fuel consumption, and flight time calculations. The dial features the signature Navitimer layout with three sub-dials for elapsed hours, minutes, and running seconds, all framed by the characteristic circular slide rule.
