The Breitling Navitimer, a horological icon since its introduction in 1952, is more than just a timepiece; it's a sophisticated instrument capable of performing a variety of functions. This comprehensive guide will delve into the intricacies of operating your Breitling Navitimer, covering everything from basic time setting to advanced features like its unique slide rule functionality and its surprising use as a sun compass. Whether you own a vintage model or the latest iteration, understanding the Navitimer's capabilities will enhance your appreciation for this legendary watch.
I. Breitling Navitimer User Manual: A General Overview
Before diving into specific models and functions, it's crucial to understand the general layout and common features shared across most Navitimer models. The Navitimer's signature feature is its iconic circular slide rule bezel. This bezel, graduated with various scales, allows for complex calculations, making it an invaluable tool for pilots and aviation enthusiasts. However, its functionality extends beyond aviation, proving useful in a variety of everyday situations.
The main watch face displays hours, minutes, and seconds, typically with subdials for chronograph functions (start, stop, reset). The chronograph allows for precise time measurement, useful for timing events, laps, or simply observing the passage of shorter time intervals. The specific arrangement and number of subdials may vary slightly depending on the model (e.g., Navitimer 01, Navitimer GMT, Navitimer Automatic).
The crown is used for winding the watch (manual wind models) and setting the time. Pushers on the case are used to operate the chronograph functions. Understanding the function of each pusher and the crown is critical to correctly using the Navitimer's features. Always refer to your specific model's manual for detailed instructions on crown and pusher operation.
II. Breitling Navitimer Owners Manual: Setting the Time and Date
Setting the time and date on your Breitling Navitimer requires careful attention. The process varies slightly depending on the specific model and whether it's a manual-wind or automatic movement. Consult your specific model's manual for precise instructions, but the general steps are as follows:
* Pulling the Crown: Gently pull the crown out to the first position. This allows you to set the time. Rotate the crown to adjust the hour and minute hands.
* Setting the Date: On models with a date function, pulling the crown to the second position usually allows you to adjust the date. Rotate the crown until the desired date is displayed.
* Pushing the Crown: Once the time and date are correctly set, push the crown back into its original position.
III. Breitling Navitimer Instructions: Utilizing the Slide Rule Bezel
The Navitimer's slide rule bezel is its most distinctive and arguably its most useful feature. This rotating bezel features various scales that allow for performing calculations related to speed, distance, fuel consumption, and more. Mastering the slide rule requires practice and a good understanding of its scales. Here's a simplified overview:
* Speed Calculation: The inner scale allows you to calculate speed. For example, knowing the distance covered (in nautical miles or kilometers) and the time taken (in hours or minutes), you can determine the average speed.
* Distance Calculation: Conversely, knowing the speed and the time, you can calculate the distance covered.
* Fuel Consumption: Certain scales can also be used to estimate fuel consumption based on distance and fuel consumption rate.
