The Breitling Navitimer, a watch synonymous with aviation heritage and sophisticated functionality, features a prominent tachymeter scale. This seemingly simple ring of numbers, however, unlocks a powerful tool for measuring speed, allowing the wearer to calculate speeds over a known distance, or distances covered in a known time. While the functionality might seem intimidating at first, understanding the principles behind the Breitling tachymeter and its practical applications – particularly when considering the nuances of speed measurement, as highlighted by the runner's experience with slower speeds – reveals its remarkable versatility. This article will delve into the intricacies of tachymeterbenutzung Breitling, exploring its use, accuracy, limitations, and the specific context of the Navitimer. We'll also touch upon various Breitling tachymeter models, their pricing, and the overall experience of using this essential complication.
Understanding the Tachymeter Scale:
The tachymeter scale on a Breitling watch, typically found around the outer bezel, is a graduated scale that allows you to measure speed based on the time it takes to cover a known distance (usually one kilometer or one mile). It's crucial to understand that the tachymeter scale is calibrated for a specific unit of distance. While most Breitling tachymeters are calibrated for one kilometer, some might be calibrated for one mile. This must be factored into your calculations.
The numbers on the tachymeter scale represent speeds in units per hour. For instance, if the chronograph hand stops at the number "60," it means the object covered the measured distance (e.g., 1 kilometer) in exactly one minute. Therefore, its speed is 60 kilometers per hour (km/h). If the chronograph hand stops at "30," the object covered the distance in two minutes, resulting in a speed of 30 km/h. The relationship is inversely proportional: the higher the number on the scale, the lower the speed, and vice versa.
Using the Breitling Tachymeter: A Step-by-Step Guide:
1. Choose your distance: Select a known distance – ideally, one kilometer or one mile, depending on your watch's calibration. This could be a marked section of road, a track, or any other measurable distance.
2. Start the chronograph: Start the chronograph function on your Breitling watch precisely as you begin traversing the chosen distance.
3. Stop the chronograph: Stop the chronograph precisely when you reach the end of the chosen distance.
4. Read the speed: Note the position of the chronograph hand on the tachymeter scale. The number at which the hand points indicates the speed in units per hour (km/h or mph).
The Runner's Perspective and the Flexibility of Distance:
As mentioned earlier, the runner's experience highlights a crucial point: measuring slower speeds using a tachymeter can be less precise. This is because the chronograph hand moves slower over longer time intervals, making accurate reading more challenging. This is where the flexibility of choosing the distance comes in handy. For slower speeds, selecting a shorter distance (e.g., 200 meters instead of 1 kilometer) will result in a shorter timing period, making the reading more precise. The resulting speed can then be extrapolated to the equivalent speed over a kilometer or mile.
