Fellow watch collector Bill Sohne recently acquired a stunning piece of horological history: a vintage Breitling 806 Navitimer APOA chronograph, complete with its original instruction manual. This acquisition sparked a renewed interest in this iconic model, prompting a deeper exploration of its intricacies, history, and value in today's market. This article will serve as a comprehensive guide, delving into the specifics of operating the Breitling Navitimer 806, its history, value, and the nuances of identifying genuine vintage pieces.
Understanding the Breitling Navitimer 806: A Pilot's Companion
The Breitling Navitimer 806, often referred to as the "APOA" (for its association with the Aéro-Postale), holds a special place in the hearts of aviation enthusiasts and watch collectors alike. Produced in limited numbers, primarily during the late 1950s and early 1960s, this model represents a pivotal moment in Breitling's history, showcasing a refined design and robust functionality perfectly suited to the demanding needs of pilots. Unlike its more famous sibling, the Navitimer Cosmonaute, the 806 is a less common find, adding to its allure and collectability. Its design, characterized by a smaller case size compared to later Navitimers, a distinctive dial layout, and often featuring a black dial, further distinguishes it within the Navitimer family.
Breitling Navitimer 806 Instructions: Decoding the Manual
Bill Sohne's acquisition of the original manual provides invaluable insight into the operation of the 806. While exact wording may vary slightly depending on the specific manual version, the core functions remain consistent. The manual typically covers:
* Setting the Time: This will involve understanding the crown's different positions. Pulling the crown to the first position allows for setting the time, while pulling it further might allow for date adjustment, if present on the specific variation. The manual would detail the correct procedure to avoid damaging the delicate movement.
* Using the Chronograph Function: The 806, being a chronograph, allows for precise time measurement. The manual would explain how to start, stop, and reset the chronograph seconds hand using the pushers. Understanding the different subdials (typically displaying seconds, minutes, and potentially hours of elapsed time) is crucial for accurate readings.
* Operating the Slide Rule Bezel: This is the defining feature of the Navitimer. The rotating bezel incorporates a circular slide rule, enabling complex calculations crucial for flight navigation, such as converting speed, distance, fuel consumption, and more. The manual would meticulously explain the different scales and their application, guiding the user through various calculations. Mastering the slide rule is a rewarding experience that truly appreciates the ingenuity of this timepiece. Different versions of the 806 may have slightly different slide rule configurations, adding further interest to researching specific examples.
* Wind and Maintenance: The manual would outline the proper method for winding the movement and highlight the importance of regular servicing to maintain accuracy and longevity. Understanding the power reserve and the signs of needing a service is crucial for preserving the watch's value and functionality.
* Troubleshooting: A section dedicated to potential issues and their resolution is typically included. This may cover problems with the chronograph function, the slide rule, or the overall timekeeping accuracy.
