Breitling navitimer

The Breitling Navitimer is an iconic mechanical wristwatch, created in 1952 for pilots featuring an integrated circular slide rule.

About this subject

The Breitling Navitimer is one of the most recognizable watches in the world, especially in the aviation segment. Launched in 1952, it was developed in partnership with the Aircraft Owners and Pilots Association (AOPA). Its most distinctive feature is the circular slide rule bezel, which enables mathematical operations and aerial navigation conversions, such as speed, fuel consumption, and flight time calculations. The movement is a mechanical chronograph, initially based on the Valjoux 72 caliber and later on the in-house Breitling Caliber 01. The dial typically features three subdials for the chronograph, with a highly legible design. The Navitimer was used by US Air Force pilots and figures like astronaut Scott Carpenter, who adapted a model for space. Although it did not go to the Moon like the Omega Speedmaster, the Navitimer is synonymous with precision and aeronautical functionality. Today, the line includes models such as the Navitimer 01, with an automatic movement and 70-hour power reserve, and the B01 version with date. The case is usually stainless steel, with options in gold and titanium. The strap can be leather or bracelet. The bezel has 120 clicks and bidirectional rotation. The slide rule requires learning but is functional for pilots. The price of a new Navitimer starts around $8,000 USD, and vintage models can exceed $20,000 at auctions.

Frequently Asked Questions

How does the Navitimer slide rule work?

The Navitimer slide rule consists of two concentric rotating discs: a fixed outer ring and an inner ring controlled by the bezel. By aligning numbers, you can multiply, divide, and convert units, such as miles to kilometers or calculate consumption rates. It is an analog tool for aerial navigation.

What is the difference between the Navitimer 01 and Navitimer 8?

The Navitimer 01 uses the in-house Breitling Caliber 01 movement with a vertical clutch chronograph and 70-hour power reserve, while the Navitimer 8 (discontinued) used ETA/Sellita calibers with cam chronographs. The 01 has a more classic design with a full slide rule; the 8 was simplified and more affordable.

Is the Breitling Navitimer suitable for diving?

No. The Navitimer is not designed for diving; its typical water resistance is 30 meters (3 ATM), sufficient for splashes but not for swimming or diving. There are specific versions like the Navitimer Superocean, but the classic model focuses on aviation, not water activities.
