The Breitling Navitimer, a watch synonymous with aviation history and sophisticated horological design, features a circular slide rule bezel that, while seemingly complex, is surprisingly intuitive once understood. This article serves as a comprehensive guide to mastering the Navitimer's slide rule, covering its functionalities, common calculations, and troubleshooting tips. We'll delve into the specifics of multiplication, division, conversion calculations, and more, effectively acting as your personal Breitling Navitimer slide rule manual.
Understanding the Navitimer's Slide Rule Bezel
Before diving into specific calculations, let's familiarize ourselves with the layout of the Breitling Navitimer slide rule bezel. Unlike digital calculators, the Navitimer utilizes a rotating bezel with various scales to perform calculations. These scales, typically including A, B, C, and D scales (and sometimes others depending on the specific Navitimer model), are arranged in a circular fashion. The key to understanding its operation lies in the relationship between these scales and the understanding of the unit index (usually marked in red on the inner scale).
This article will primarily focus on the most common scales (A, B, C, and D) and their use in basic arithmetic operations. More advanced calculations and specialized scales found on certain models will be addressed later.
Breitling Navitimer Bezel Chart & Diagram:
While a detailed visual chart and diagram are beyond the scope of text, imagine the bezel as a circle divided into segments, each representing a numerical value. The scales are arranged concentrically, allowing for the manipulation of numbers by rotating the bezel. A visual representation (easily found online by searching "Breitling Navitimer bezel diagram" or "Breitling Navitimer bezel chart") is crucial for understanding the spatial arrangement of the scales. These diagrams clearly show the relationship between the scales and the unit index, facilitating a more intuitive understanding of the calculation process. Many online resources, including official Breitling material and dedicated watch enthusiast forums, offer high-quality diagrams and charts.
Multiplication with the Navitimer Slide Rule:
To multiply with the Navitimer, the unit index (the red "1" on the inner scale, often referred to as the "index") plays a crucial role. This is the fundamental starting point for most calculations. Let's consider an example: 2 x 3.
1. Set the Index: Rotate the bezel until the "1" (unit index) on the C scale is aligned with the "2" on the D scale.
2. Find the Second Number: Locate the "3" on the C scale.
3. Read the Result: The number directly below the "3" on the C scale, on the D scale, will be the answer: 6.
This process works for a wide range of multiplications. The key is always aligning the unit index with the first number on the D scale and then finding the second number on the C scale to read the result on the D scale. More complex multiplications follow the same principle. For example, to calculate 2.5 x 4.2, align the unit index with 2.5 on the D scale, find 4.2 on the C scale, and read the answer (approximately 10.5) on the D scale.
Division with the Navitimer Slide Rule:
Division is the inverse of multiplication, and its execution on the Navitimer is equally straightforward. Let's use the example 6 / 3.
