The Breitling Navitimer is impressive, both in form and function. While the watch itself is certainly remarkable, with its polarizing dimensions and reliable chronograph movement, the most captivating aspect lies in its multifaceted functionality. This isn't just a timepiece; it's a sophisticated flight computer strapped to your wrist, a legacy that continues to resonate with pilots, enthusiasts, and collectors alike. This article will explore the diverse functions of the Breitling Navitimer, examining its historical significance and navigating the complexities of purchasing one, whether new, pre-owned, or used. We'll also delve into the various models available and provide guidance on finding the best price for your desired Navitimer.
The Heart of the Navitimer: The Slide Rule Bezel
The defining characteristic of the Navitimer, and the source of much of its functionality, is its circular slide rule bezel. This ingenious feature, a hallmark of the watch's design since its introduction in 1952, allows for a surprising array of calculations crucial for aviation. Before the advent of sophisticated handheld flight computers, pilots relied on the Navitimer's bezel to perform critical calculations related to:
* Speed and Distance: The bezel allows pilots to calculate ground speed, airspeed, distance traveled, and fuel consumption based on various factors like time, distance, and fuel flow. This was particularly vital in the era of piston-engine aircraft, where precise fuel management was crucial for long flights.
* Fuel Consumption: Accurate fuel calculations are essential for safe flight. The Navitimer's slide rule facilitated the calculation of fuel burn rates, allowing pilots to estimate their remaining fuel and plan accordingly, avoiding dangerous situations.
* Rate of Climb/Descent: By inputting relevant data, pilots could determine their rate of climb or descent, important for navigating challenging terrain and maintaining safe altitudes.
* Conversion Calculations: The bezel facilitates conversions between different units of measurement, including miles to kilometers, gallons to liters, and more, a critical function for international flights.
While modern technology has largely replaced the need for manual flight calculations, the slide rule bezel remains a testament to the Navitimer's innovative design and its historical significance. It's a tangible link to the past, a reminder of the ingenuity required for aviation in its earlier days. The mastery of the slide rule bezel requires practice and understanding, but for many, this is part of the charm and appeal of the Navitimer. Numerous online resources and tutorials are available for those seeking to master this unique feature.
Beyond the Bezel: The Chronograph Function
The Navitimer is more than just a slide rule; it's a fully functional chronograph. This feature allows for precise time measurement, crucial for timing laps, tracking flight times, or simply measuring elapsed time. The chronograph function typically includes:
* Start/Stop/Reset Functions: These basic functions allow the user to start, stop, and reset the chronograph's seconds hand, enabling accurate timing of events.
* Independent Seconds Hand: The chronograph's seconds hand operates independently of the main seconds hand, allowing for clear and precise measurement of elapsed time.
* Subdials: The Navitimer typically features subdials that display minutes and hours of elapsed time, providing a comprehensive record of the duration of timed events.
The chronograph function, combined with the slide rule bezel, makes the Navitimer a truly versatile instrument, capable of handling a wide range of timing and calculation tasks. The accuracy and reliability of the chronograph movement are key factors in the Navitimer's enduring appeal.
