Breitling Navitimer Cosmonaute Vintage Tritium A-12019 Pre-Owned 1997

“Master time, conquer infinity, and gaze at the stars.”

There are watches that merely measure time, and then there are those that write history with it. The Breitling Navitimer Cosmonaute reference A-12019 is one of those legends. A true tribute to space exploration, it is the only mechanical wristwatch to have accompanied an American astronaut into space during Scott Carpenter’s orbital flight in 1962. More than just a chronograph, it embodies the watchmaking genius dedicated to the pioneers of space adventure.

At first glance, the Navitimer Cosmonaute stands out with its unique 24-hour dial, which revolutionizes the way time is displayed. Designed to allow astronauts to distinguish day from night while orbiting the Earth every 90 minutes, this unprecedented dial offers a fascinating reading experience: the hour hand makes a full rotation in 24 hours instead of the usual 12. This way, you instantly know whether it’s 10 a.m. or 10 p.m.—an unprecedented advantage, even here on Earth!

Imagine using it in everyday life: during polar expeditions or in the Arctic, where the sun doesn’t set or rise for weeks, this 24-hour dial provides a reliable time reference. And in the city, it brings an original style, perfect for sparking curiosity and starting conversations. Paired with raw denim jeans and a crisp white shirt, this Cosmonaute adopts an unexpected casual-chic look, all while affirming your taste for exceptional instruments.

Technically, this Breitling Navitimer Cosmonaute A-12019 features a 41.5 mm stainless steel case, ideally proportioned for a bold yet balanced presence. Its bidirectional rotating bezel, equipped with the iconic circular slide rule—a hallmark of the Navitimer—allows complex calculations: speeds, distances, rates of climb, fuel consumption… essential functions for pilots, but also captivating for precision enthusiasts. Inside beats the hand-wound Breitling caliber 12, derived from the legendary Lemania 1873. This movement is renowned for its robustness, precision, and of course, its unique 24-hour display faithful to the original model’s tradition. Protected by a domed hesalite crystal, the watch offers perfect readability day or night, thanks to luminous indexes and hands. Its steel bracelet with a folding clasp ensures optimal comfort and an elegant look.

The Navitimer Cosmonaute belongs to the lineage of iconic chronographs that have accompanied some of the greatest aerial and space achievements of the 20th century. Since its introduction in the Navitimer line, it has embodied Breitling’s pioneering spirit and its ability to push the boundaries of time and space.
