Breitling navitimer

The Breitling Navitimer is an iconic wristwatch, known for its circular slide rule and association with aviation.

About this subject

The Breitling Navitimer was launched in 1952 and quickly became the official watch of the Aircraft Owners and Pilots Association (AOPA). Its main feature is the circular slide rule, which allows pilots to perform navigation calculations such as fuel consumption, speed, and unit conversions without additional tools. The dial design is complex, with three subdials and a rotating bezel that integrates the slide rule. The automatic Caliber B01 movement, introduced in 2009, brought chronograph function and a 70-hour power reserve.

Over the decades, the Navitimer has undergone several updates while maintaining its classic aesthetic. Models like the Navitimer 1 B01 Chronograph and the Navitimer Ref. 806 continue to be produced, paying homage to the original versions. The case typically ranges from 41 to 46 mm, with options in stainless steel, gold, or titanium. The bracelet can be leather or metal, featuring the characteristic beads-of-rice design.

Culturally, the Navitimer has transcended its tool-watch origins. Celebrities such as Miles Davis and Serge Gainsbourg wore the model, and it appears in films like Top Gun: Maverick. Breitling also supports historic aviation with the Breitling Jet Team. The combination of Swiss precision, functionality, and timeless design makes the Navitimer a coveted piece for collectors.

Notably, the name Navitimer combines navigation and time, reflecting its original purpose. The slide rule is based on Euler's circle, facilitating multiplication and division. A special edition, the Navitimer Cosmonaute, was used in space flights, including NASA's Aurora 7 mission in 1962.

Frequently Asked Questions
