Have you ever wondered what the additional numbers on the bezel of a Breitling Navitimer watch are for? They're not just decorative flourishes; they're a fully functional circular slide rule, a testament to the watch's rich aviation heritage and a surprisingly useful tool, even in our digital age. This comprehensive guide will walk you through the intricacies of using this fascinating feature, covering everything from basic operations to more advanced calculations. We’ll explore the layout of the Breitling Navitimer bezel, provide clear instructions, and offer resources for further learning.
Understanding the Breitling Navitimer Bezel Chart and Diagram
Before diving into calculations, it's crucial to understand the layout of the Navitimer's bezel. Unlike a standard ruler, the Navitimer's slide rule uses a circular scale, making it compact and elegant. A typical Breitling Navitimer bezel chart (easily found online or in a Breitling Navitimer bezel manual) will show the various scales and their functions. A Breitling Navitimer bezel diagram will visually represent the arrangement of these scales, often color-coded for clarity. These resources are indispensable for understanding the relationship between the different scales and how to position them correctly for various calculations.
The key components of the Navitimer's slide rule are:
* The Outer Bezel: This rotating bezel contains the primary scales used for calculations. These scales are usually labeled with letters such as A, B, C, D, and sometimes E. The specific scales and their labeling may vary slightly depending on the Navitimer model and its year of manufacture.
* The Inner Rotating Rehaut: This inner ring, often fixed, provides a reference point for reading the results.
* The Slide Rule's Indices: The numbers and markings on the scales represent logarithmic values, allowing for multiplication, division, and other calculations.
Essential Scales and Their Functions
The most common scales found on a Breitling Navitimer slide rule are:
* Scale A & B: These are typically the outer scales, usually identical and used for squares and square roots. They are arranged so that the square of a number on scale C is found directly opposite on scale A or B.
* Scale C & D: These are the most frequently used scales. Scale C is the rotating scale, and Scale D is the fixed scale. They are used primarily for multiplication and division. To multiply two numbers, align the "1" on scale C with the first number on scale D. The product of the two numbers is then found on scale D, opposite the second number on scale C. Division works in reverse.
* Scale E: This scale, if present, is used for cubes and cube roots.
* Other Specialized Scales: Some Navitimer models include additional scales for specific calculations, such as those related to fuel consumption, flight time, or currency conversion. These specialized scales require specific instructions, often found in a Breitling slide rule manual PDF or a dedicated Breitling Navitimer slide rule guide. These manuals provide detailed explanations and examples.
Basic Calculations: Multiplication and Division
Let's illustrate multiplication and division using scales C and D. Assume we want to multiply 2 x 3:
1. Align: Rotate the bezel until the "1" on scale C aligns with the "2" on scale D.
2. Find the Result: Locate the "3" on scale C. The number directly below it on scale D is the result: 6.
