The Breitling Navitimer is an iconic watch, instantly recognizable for its distinctive slide rule bezel and sophisticated chronograph functionality. This guide will walk you through the basics of using the chronograph feature, a key element of this legendary timepiece. We'll also touch upon some frequently asked questions surrounding purchasing a Navitimer, helping you navigate the world of authentic Breitling Navitimers and choose the perfect model for you.
USING THE CHRONOGRAPH
The Navitimer's chronograph allows you to precisely measure elapsed time. Understanding its operation is crucial to fully appreciating this versatile instrument. Let's explore the process step-by-step:
I. MEASURING A SINGLE SHORT TIME
This is the most basic chronograph function. The Navitimer typically uses two pushers, conventionally labeled A and B.
1. Press pushpiece A to start the chronograph. This initiates the timing sequence. The chronograph seconds hand (hand 3, usually a red-tipped hand) will begin moving, indicating elapsed seconds. Observe that the other chronograph hands (typically a minute counter and a hour counter) will also start to move, depending on the duration of the timing.
2. Stop the measurement by pressing pushpiece A again. This halts the chronograph hands at the precise elapsed time. You can read the time directly from the chronograph hands: seconds on the seconds subdial, minutes on the minute counter, and hours on the hour counter (if applicable).
3. Reset the chronograph to zero by pressing pushpiece B. This returns all chronograph hands to their starting position (at 12 o'clock), preparing the watch for the next measurement. Note that some models may require a slightly different sequence (e.g., holding pushpiece B). Refer to your watch's manual for precise instructions.
II. MEASURING MULTIPLE SHORT TIMES (ADDITIVE TIMING)
This function allows you to accumulate several short time intervals.
1. Start the chronograph by pressing pushpiece A.
2. Stop the first interval by pressing pushpiece A again. The chronograph hands will indicate the elapsed time for the first interval.
3. Press pushpiece A again to restart the chronograph. The chronograph will continue timing from where it left off, accumulating the time of subsequent intervals.
4. Repeat steps 2 and 3 for each additional interval.
5. Stop the final interval and reset using pushpiece B as described above. The total accumulated time will be displayed on the chronograph hands.
III. MEASURING LAP TIMES (SPLIT TIMES)
Some Navitimer models offer a lap time function. This allows you to measure multiple intervals within a longer time period without stopping the main chronograph. The exact method varies slightly depending on the model; consult your user manual for specific instructions. Generally, a second pusher (pushpiece B) is involved to record intermediate lap times.
IV. USING THE SLIDE RULE BEZEL
Beyond the chronograph, the Navitimer’s distinctive slide rule bezel is a powerful tool for performing calculations. This feature allows quick conversions between various units, including currency exchange rates, fuel consumption, speed and distance, etc. Mastering the slide rule requires practice and understanding of its various scales. Numerous online resources and instructional videos are available to guide you through its intricate workings.
