Breitling Navitimer B02 Chronograph Cosmonaute 41 MM Stainless Steel with Black Dial

The Navitimer B02 Cosmonaute is more than a chronograph — it is a direct descendant of the first Swiss wristwatch worn in space. This 41 mm stainless steel edition preserves the original mission-ready spirit with its trademark 24-hour dial, a configuration designed to help astronauts distinguish day from night during orbit.

The black dial features crisp contrasting registers, vintage-toned Arabic numerals, and a finely executed slide-rule bezel — an aviation icon engineered for real computational utility. At its heart is the Breitling Manufacture Caliber B02, a hand-wound movement built for mechanical purists, offering COSC-certified precision and an architecture tailored to the historical Cosmonaute layout.

The polished steel case, slim profile, and multi-link bracelet bring refined ergonomics while maintaining the rugged authenticity of a professional flight instrument. The result is a collector-grade timepiece that unites space-flight heritage, mechanical craftsmanship, and unmistakable Navitimer aesthetics.

This is one of Breitling’s most important references — a tribute to exploration, engineering, and the legacy of human innovation.
