What is a Tachymeter?
A tachymeter is a feature commonly found on the bezel or dial of a watch that allows for the measurement of speed, distance, or elapsed time. It is a useful tool for athletes, drivers, and outdoor enthusiasts who need to track and calculate their speed or distance traveled. The tachymeter scale is typically marked around the bezel or the outer edge of the dial, and it is often denoted by numbers and markers.
The tachymeter scale is used in conjunction with the chronograph function of a watch, which is a stopwatch feature that allows you to measure elapsed time. By utilizing the tachymeter scale, you can calculate a speed or distance based on the time it takes to travel a known distance or complete a specific activity.
Tachymeters have been widely used in racing sports, such as motorsports and track and field events, where measuring speed and elapsed time is crucial. However, they can also be handy in everyday life for measuring the speed of a moving object, estimating the time it takes to travel a certain distance, or evaluating the duration of an activity.
It is important to note that while many high-end and specialized watches feature a tachymeter, not all watches come equipped with this function. Therefore, if you are specifically looking to use a tachymeter for a particular purpose, be sure to check if your watch has this feature.
How Does a Tachymeter Work?
A tachymeter works by using a combination of time and speed to calculate different measurements. It relies on the principle that for a given speed, the time it takes to travel a known distance will be constant. By utilizing the tachymeter scale on the watch, you can easily determine your speed, distance, or elapsed time.
When using a tachymeter, you will typically start the chronograph function of your watch to measure the time it takes to cover a specific distance. The tachymeter scale is usually marked with numbers from 60 to 400, denoting different units of speed, such as kilometers per hour (km/h) or miles per hour (mph).
To use the tachymeter, follow these steps:
- Start the chronograph function of your watch when the event or activity begins.
- For example, if you are measuring the speed of a car, start the chronograph when the car crosses a mile marker on the road.
- Stop the chronograph function when the car crosses the next mile marker.
- Read the position of the chronograph hand on the tachymeter scale to determine the speed.
Let’s say the chronograph hand points to 80 on the tachymeter scale. This means that the car was traveling at 80 miles per hour.
It is important to note that the tachymeter scale on a watch is typically calibrated for a specific unit of distance. For example, if the tachymeter is calibrated for kilometers per hour (km/h), you will need to know the distance covered in kilometers to calculate the speed accurately. Similarly, if the tachymeter is calibrated for miles per hour (mph), you will need the distance covered in miles.
By understanding how a tachymeter works and following the steps mentioned above, you can easily use this feature to measure speed, distance, or elapsed time with accuracy and convenience.

Remember that the tachymeter scale on your watch may be calibrated for a specific unit of distance, such as kilometers or miles. Ensure that you know the correct unit to use when interpreting the tachymeter reading accordingly.
By following these step-by-step instructions, you can effectively utilize the tachymeter feature on your watch to measure speed, distance, or elapsed time with precision and accuracy.
Calculating Speed with a Tachymeter
One of the primary uses of a tachymeter on a watch is to calculate speed. By following a simple formula, you can determine the speed at which an object is moving based on the time it takes to cover a known distance. Here’s how to calculate speed using a tachymeter:
- Identify the Tachymeter Scale: Locate the tachymeter scale on your watch, usually marked around the bezel or dial.
- Start the Chronograph: Begin the chronograph function on your watch when the object you want to measure starts its movement.
- Measure the Time: Let the chronograph run until the object has covered a specific distance. For example, if you’re measuring the speed of a car, let the chronograph run until the car has traveled one mile.
- Stop the Chronograph: Stop the chronograph function when the desired distance has been covered.
- Read the Tachymeter Scale: Look at the position of the chronograph hand on the tachymeter scale and note the corresponding number or marker.
Once you have the tachymeter reading, you can use the formula “Speed = Distance/Time” to calculate the speed. Ensure that you use the correct unit of distance (e.g., kilometers or miles) and time (e.g., seconds or minutes) based on the tachymeter scale calibration.
For example, if the tachymeter reading is 80 and the distance covered is 1 mile, divide 1 mile by the recorded time on the chronograph to calculate the speed in miles per hour (mph).
It’s worth noting that a tachymeter can provide accurate speed measurements for objects traveling at relatively high speeds. However, it may not be accurate for objects moving at very low speeds due to the limitations of the chronograph function and the size of the tachymeter scale.
By understanding how to calculate speed using a tachymeter and applying the appropriate formula, you can easily determine the speed at which an object is moving with the help of your watch.
Measuring Distance with a Tachymeter
In addition to calculating speed, a tachymeter can also be used to measure distance. By leveraging the tachymeter scale on your watch and considering the time it takes to travel a known distance, you can estimate the distance covered by an object. Here’s how to measure distance using a tachymeter:
- Identify the Tachymeter Scale: Locate the tachymeter scale on your watch, typically marked around the bezel or dial.
- Start the Chronograph: Initiate the chronograph function on your watch when the object you want to measure starts moving.
- Measure the Time: Allow the chronograph to run as the object covers a specific distance. For example, if you’re measuring the distance traveled by a runner, let the chronograph run until the runner completes one kilometer.
- Stop the Chronograph: Stop the chronograph function when the desired distance has been covered.
- Read the Tachymeter Scale: Observe the position of the chronograph hand on the tachymeter scale and take note of the corresponding number or marker.
Once you have the tachymeter reading, you can use the formula “Distance = Speed × Time” to estimate the distance covered. Ensure that you use the correct unit of speed (e.g., kilometers per hour or miles per hour) and time (e.g., seconds or minutes) based on the tachymeter scale calibration.
For example, if the tachymeter reading is 200 and the speed at which the object is moving is 50 km/h, you can calculate the distance covered by multiplying the speed by the time recorded on the chronograph.
It is worth noting that the accuracy of distance measurements using a tachymeter may depend on factors such as the precision of the chronograph function and the size and calibration of the tachymeter scale on your watch.
