Key Features
- In-House Breitling Caliber B01 Movement: This self-winding mechanical movement is entirely developed and manufactured by Breitling, offering exceptional precision and a 70-hour power reserve. It includes a column-wheel chronograph mechanism for smooth, accurate timing of events up to 1/4th of a second.
- 46mm Stainless Steel Case: The substantial case size provides a commanding presence on the wrist while maintaining Breitling’s signature balance of form and function. Crafted from polished and brushed stainless steel, it resists wear and retains its finish over time.
- Circular Slide Rule Bezel: A defining feature of the Navitimer line, the bidirectional rotating bezel with its engraved slide rule scale allows pilots and travelers to perform essential calculations such as fuel consumption, climb rates, and unit conversions directly from the dial.
- Black Dial with Silver Sub-Dials: The high-contrast dial features three sub-dials for chronograph functions—30-minute, 12-hour, and running seconds—along with applied hour markers and luminous hands for enhanced legibility in low-light conditions.
- Sapphire Crystal with Anti-Reflective Coating: The front crystal is made of scratch-resistant sapphire with an anti-reflective treatment on both sides, ensuring clear visibility from any angle and protecting against daily wear.
- Black Alligator Leather Strap: The hand-stitched strap offers comfort and sophistication, secured with a stainless steel folding buckle for secure wear. The leather is durable and develops a rich patina over time.
- Water Resistance to 30 Meters (3 ATM): While not designed for diving or prolonged submersion, the watch can withstand splashes, rain, and brief immersion, making it suitable for everyday use and light water exposure.
