What is the new Navitimer B02 Chronograph 41 Cosmonaute and the Navitimer B09 Chronograph 41?
Breitling’s Navitimer has its roots in 1952. Developed as a tool for pilots, its circular slide rule and chronograph enabled “pilots to perform calculations with the twist of a bezel and track elapsed time at the press of a pusher.” A decade later, the brand modified the Navitimer for spaceflight at the request of Scott Carpenter, one of the original seven astronauts from NASA’s Mercury program.
The Navitimer B02 Chronograph 41 Cosmonaute (header image) and the Navitimer B09 Chronograph 41 join the brand’s core collection.
“The Navitimer has always evolved with the people who wear it. The B09 brings the look and feel of the classic 1960s Navitimer into the modern collection, and the Cosmonaute tells the story of how the Navitimer went from the cockpit to space. These modern-retro pieces show just how much history is built into the Navitimer collection.” – Georges Kern, CEO of House of Brands.

What do we think?
Pilot’s watches are ubiquitous. Watch enthusiasts and collectors can often find it challenging to choose. The Breitling Navitimer stands out. A genuine pilot’s watch, it is mighty impressive. It can hold its own among chronographs costing 10 times or more.

Whether you choose the “standard version” or the “Cosmonaute,” you are getting an iconic, distinct design soaked in aviation and space heritage, powered by an in-house column-wheel chronograph movement, and offered at a competitive price. My personal favourite is the Cosmonaute on the brown calf-leather strap, or the standard version with a blue dial on the blue calf-leather strap.
