Breitling Navitimer B01 Chronograph 46 Black Dial Watch AB0137211B1A1

The Breitling Navitimer B01 Chronograph 46mm (Ref. AB0137211B1A1) represents the definitive pilot’s chronograph, maintaining every functional element that made the Navitimer legendary since 1952. The bidirectional slide rule bezel performs genuine aviation calculations for fuel consumption, flight time, and navigation, not decorative elements but working tools that pilots actually use when electronic systems fail.

At 46mm, this commands serious wrist presence but the sizing serves a purpose. Professional cockpit use demands high legibility, and the substantial case accommodates the complex chronograph movement while providing sufficient dial space for clear slide rule operation. The black dial offers sophisticated appearance with the high contrast visibility essential for flight operations.

The Manufacture Calibre B01 delivers COSC chronometer certification with 70-hour power reserve, tested to simulate 16 years of wear including 60,000 shocks at 500G. This isn’t marketing hyperbole, the movement undergoes comprehensive testing protocols because equipment failure in aviation has serious consequences. The column wheel chronograph provides precise operation essential for professional flight timing.

The stainless steel construction and mixed brushed/polished finishing create visual depth while maintaining the robust build quality demanded by aviation environments. The bracelet system ensures secure attachment throughout demanding flight operations.

This Navitimer suits buyers who want authentic aviation heritage with proven functionality. Since 1952, the Navitimer has served professional pilots who needed sophisticated timing and calculation capabilities. The slide rule bezel performs real mathematical operations, the 46mm case ensures cockpit legibility, and the Manufacture movement delivers the reliability that flight safety demands. It’s aviation equipment refined for luxury use, not a fashion watch with aviation styling.
