The Breitling Navitimer is impressive, both in form and function. While the watch itself is certainly remarkable, with its polarizing dimensions and reliable chronograph movement, the most captivating aspect lies in its ingenious design and the seamless integration of its various complications. This article will delve into the mechanics of the Navitimer, exploring its functionality, variations, and the reasons behind its enduring popularity. We will also touch upon pricing and different model variations, including the Breitling Navitimer Automatic 35, 41, and 46, as well as used options and those featuring diamond dials.
The Heart of the Navitimer: The Movement
The core of any Navitimer's functionality lies in its movement. While Breitling has used various movements throughout the Navitimer's history, most modern iterations utilize self-winding (automatic) movements. These movements are intricate mechanisms of gears, springs, and levers that translate the kinetic energy from the wearer's wrist movement into power, winding the mainspring. This mainspring then releases its stored energy gradually, powering the watch's functions. The specific caliber used will vary depending on the model and year of manufacture. For example, earlier models might house movements from ETA, while newer models frequently feature in-house Breitling movements, often offering improved performance and features. These in-house movements are a testament to Breitling’s commitment to horological excellence, showcasing their dedication to precision and reliability.
The Iconic Slide Rule Bezel: A Pilot's Essential Tool
The Navitimer's most distinctive feature, however, is its circular slide rule bezel. This intricate rotating bezel is not merely an aesthetic element; it's a powerful flight calculator. Before the advent of sophisticated onboard flight computers, pilots relied on the Navitimer's bezel for crucial calculations, including:
* Speed Calculation: By timing a known distance, the pilot could calculate ground speed.
* Fuel Consumption: The bezel could be used to estimate fuel consumption based on time and fuel burn rate.
* Conversion Calculations: Various scales on the bezel allowed for quick conversions between units of measurement, like kilometers to nautical miles or gallons to liters.
* Time Zone Conversions: While not as precise as dedicated GMT functions, the bezel could assist with approximate time zone calculations.
The slide rule functions through a series of scales etched onto the bezel and the dial. By aligning specific markers on the bezel with corresponding markers on the dial, pilots could perform these complex calculations quickly and accurately, a crucial advantage in the cockpit. Even today, the slide rule remains a fascinating and functional element, though its primary use has shifted from essential flight computation to a unique and historical feature appreciated by watch enthusiasts.
Chronograph Functionality: Precise Time Measurement
Beyond the slide rule, most Navitimer models incorporate a chronograph function. This allows the wearer to measure elapsed time with precision. The chronograph typically features three sub-dials:
* Seconds Counter: Measures seconds elapsed since the chronograph was activated.
* Minutes Counter: Measures minutes elapsed.
* Hours Counter: Measures hours elapsed.
These sub-dials work in concert with the chronograph pushers (typically located at 2 and 4 o'clock), allowing the wearer to start, stop, and reset the chronograph function accurately. The precision of the chronograph is a testament to the quality of the movement within the Navitimer.
