With its busy dial and circular slide-rule bezel, the Breitling Navitimer is one of the most distinctive watches ever made. Built as a flight computer for pilots in the 1950s, it remains one of the longest continuously produced chronographs. Here's the background ahead of our review.

History

Breitling was founded in 1884 by Léon Breitling in Saint-Imier, Switzerland, later moving to Grenchen. The company became a chronograph specialist, and in the 1930s and 1940s developed features including the second independent chronograph pusher and the Chronomat, which incorporated a logarithmic slide rule.

In 1952, Willy Breitling, grandson of the founder, was approached by the Aircraft Owners and Pilots Association (AOPA), and the result was the Navitimer — a combination of "navigation" and "timer." Its rotating bezel and dial scale formed a circular slide rule that pilots could use to calculate ground speed, fuel consumption, rate of climb or descent, distance, and unit conversions. AOPA adopted it as its official timepiece. Early AOPA versions carried the association's winged logo; a version with Breitling branding reached the public in the mid-1950s, later known by reference number 806.

On May 24, 1962, Mercury astronaut Scott Carpenter wore a custom Navitimer with a 24-hour dial during his Aurora 7 orbital flight. That model became the Navitimer Cosmonaute.

In 1969, Breitling was part of the consortium (with Heuer-Leonidas, Hamilton-Buren, and Dubois-Dépraz) that introduced one of the first automatic chronograph movements, the Chrono-Matic.

How the slide rule works

The outer rotating scale and inner fixed scale are both logarithmic. By aligning numbers on the two scales, you can multiply, divide, and solve ratios. For example, aligning the "MPH" index with a known speed shows distances traveled for given times. A red "10" marker serves as the unit index. Specialized marks handle conversions such as statute miles, nautical miles, and kilometers. Most owners today use it as a conversation piece, but it does work.

A pilot's watch in a digital cockpit

Electronic flight computers and glass cockpits have replaced slide rules in aviation, so the Navitimer's bezel is now more heritage than necessity. That's true of most tool watches. The appeal is the connection to an era when pilots did these calculations by hand.
