The Breitling Navitimer, a watch synonymous with aviation history and precision, is instantly recognizable by its iconic circular slide rule bezel. This seemingly complex feature, however, is a testament to ingenious engineering, offering pilots and enthusiasts alike a powerful tool for quick calculations crucial in flight planning and navigation. While modern technology has largely supplanted the slide rule in many contexts, the Breitling slide rule bezel remains a fascinating and functional element, a tangible link to a bygone era of analog computation. This article will delve deep into the intricacies of the Breitling slide rule bezel, exploring its functionality, its historical significance, and its enduring appeal.
Understanding the Breitling Slide Rule: More Than Just a Pretty Face
The Breitling slide rule bezel is not simply a decorative element; it’s a sophisticated analog computer etched onto the watch's rotating bezel. Unlike digital calculators, it relies on the manipulation of scales and indexes to perform calculations. This requires a degree of understanding and practice, but mastering its use unlocks a remarkable ability to perform complex calculations quickly and efficiently, without the need for an external device. The statement, "The computer portion of the watch will require a little time and patience to master, if the pilot is unfamiliar with standard flight computers," aptly reflects the learning curve involved. However, the rewards of understanding this intricate system are significant.
A Detailed Look at the Breitling Slide Rule Bezel Diagram:
A clear understanding of the Breitling slide rule bezel diagram is paramount to its successful use. The bezel typically features several concentric scales, each serving a specific purpose in flight calculations. While the exact arrangement and labeling might vary slightly depending on the specific Navitimer model and year of production, the core principles remain consistent. Let's break down the common scales:
* Inner Scale (often RPM/Fuel Consumption): This scale is frequently used to calculate fuel consumption based on engine revolutions per minute (RPM) and fuel flow rate. By aligning the appropriate markers, a pilot can quickly estimate the remaining flight time based on fuel reserves.
* Outer Scale (often Speed/Distance/Time): This is typically the primary scale for navigation calculations. It's used to solve problems involving speed, distance, and time. By aligning the appropriate markers, a pilot can determine the flight time required to cover a specific distance at a given speed, or conversely, calculate the distance covered given a speed and time.
* Intermediate Scales (various functions): Depending on the model, intermediate scales can be found between the inner and outer scales. These scales can be used for various calculations, including conversions between units (e.g., kilometers to nautical miles), or for specialized computations related to flight planning.
Breitling Navitimer Slide Rule Explained: Deciphering the Scales
The Breitling Navitimer slide rule's functionality stems from the logarithmic scales etched onto its bezel. These scales are arranged in a way that allows for multiplication and division through simple alignment of markers. For example, to multiply two numbers, one would align the index of one scale with the first number on another scale. The result of the multiplication would then be read off at the location of the second number on the first scale. Division is performed similarly, but in reverse. While this might seem abstract, understanding the underlying logarithmic principle is key to mastering the slide rule.
