Breitling navitimer

The Breitling Navitimer is an iconic mechanical chronograph, known for its slide rule bezel and aviation heritage.

About this subject

Introduced in 1952, the Breitling Navitimer was designed to meet the needs of general aviation pilots. Its defining feature is the circular slide rule bezel, which enables mathematical calculations such as distance, speed, and fuel consumption conversions without external tools. The bezel is bidirectional and aligns inner and outer scales to perform these computations.

The Navitimer's aviation ties became official in 1954 when the Aircraft Owners and Pilots Association (AOPA) adopted it as its official timepiece, cementing its reputation among pilots and enthusiasts. Early versions used the manual-wind Venus 178 movement, later replaced by automatic calibers like the Valjoux 7750 and Breitling's in-house B01 movement.

The Navitimer's design features a complex dial with subdials for chronograph hours, minutes, and seconds, plus a date window. Cases typically range from 41 to 46 mm, with a fluted crown and pushers. Hour markers and hands are polished steel for readability. Dials come in black, blue, or green, paired with leather or steel bracelets.

Frequently Asked Questions

What is the Navitimer's slide rule bezel?

It is a circular scale on the bezel that allows pilots to perform navigation calculations such as average speed, fuel consumption, and distance conversion by rotating the bezel to align numbers.

Which movement does the Breitling Navitimer use today?

Modern Navitimers use the in-house Breitling B01 caliber, an automatic chronograph movement with 70 hours of power reserve and COSC certification.

Is the Navitimer suitable for diving?

No. The Navitimer is not designed for diving; its water resistance is limited (about 30 meters). For aquatic activities, Breitling offers the Superocean line.
