What is a Tachymetric Scale?
A tachymetric scale, also referred to simply as a tachymeter, is a form of measurement tool typically found on the rim of a chronograph watch. It is used to compute a speed based on travel time or measure distance based on speed. Derived from the Greek word tachymetron, it denotes “rapid measure.”
Purpose of a Tachymetric Scale
In essence, a tachymeter serves a quite straightforward but crucial function: it scales time into speed. In the realm of wearable timepieces, like wristwatches, a tachymeter is used for measuring speed (in kilometers or miles per hour) based on time traveled, or measuring distance traveled given a known speed.
This measurement tool plays a significant role in various industries where speed and time measurement are crucial.
Principle Behind a Tachymetric Scale
A tachymeter comprises an engraved numbered scale, typically located around a watch’s bezel or, in some designs, around the outer rim of the dial.
To understand effectively how a tachymeter works, it is essential to know one principle – the numbers inscribed on the tachymeter scale represent the speed at which an event occurs, within a set time frame.
For example, if you wished to determine your speed over a known distance of one mile or one kilometer, you would start your watch’s chronograph at the beginning of the route, and then stop it at the end.
The second hand’s position on the tachymeter scale shows your average speed over that distance.
Tachymeter: A Valuable Tool on Chronograph Watches
Despite its limitations, a tachymetric scale enhances the functionality, design, and appeal of a chronograph watch. With the ability to not only tell time but also measure speed and distance, they are particularly useful and appealing to athletes, pilots, and anyone who values the fusion of style and functionality in their timepieces.

Despite the modern era’s digital advances, the accuracy and vintage charm of a traditional tachymeter continue to sustain its relevance and trustworthiness.
The Roots of the Tachymetric Scale
Today, the tachymetric scale is widely utilized for gauging speed based on time traveled or determining distance based on speed. This tool is particularly recognized for its incorporation in the bezel of chronograph watches.
Yet, its humble beginnings are rooted in the complex field of mathematics. The inception of the tachymetric scale can be traced back to the 19th century, thanks to the collaborative work of mathematicians, engineers, and watchmakers.
The term “tachymeter” originates from the fusion of two Greek words, “tachos” translating to “speed”, and “metron” which implies “measure”.
It was first christened by Benjamin Louis Francœur, a French mathematician and astronomer in 1809. Initially, the tachymeter’s role was within the industry, particularly in assessing machine speeds.
The Evolution and Broad Application of the Tachymetric Scale
With the advent of motorsports in the 20th century, the tachymetric scale began to take its place on the features of timepieces. Brands of luxury watches, such as TAG Heuer and Rolex, recognized its potential and enhanced its functionality by incorporating it within the design of their chronographs.
The “Rolex Oyster Perpetual Cosmograph Daytona”, for instance, is popularly known for its tachymetric scale engraved on the bezel. Its use is not confined to motorsports; aviators, astronauts, and even medical professionals also leverage the capabilities of the tachymetric scale.
For example, Neil Armstrong, Buzz Aldrin, and Michael Collins, the Apollo 11 astronauts, used a watch equipped with a tachymeter during their historic moon landing mission.
Furthermore, some doctors and nurses use it to calculate a patient’s heart rate over a minute, demonstrating the incredible versatility of the tachymetric scale.
Understanding the Tachymetric Scale
A tachymetric scale essentially works on the principle of converting elapsed time (in seconds per unit) to speed (in units per hour). Calculations using a tachymeter are based on a straightforward mathematical concept: Rate equals Distance divided by Time.
While its operational method might sound complex, using the tachymetric scale is rather simple. Select a fixed distance (like a mile or a kilometer), then start the chronograph at the beginning of the distance.
Once the distance is covered, the second hand on the chronograph will point to the speed scale, indicating the average speed.
However, it is important to note that the accuracy of the measurement with a tachymetric scale relies on maintaining a consistent speed. Thus, if the speed varies significantly while covering the distance, the calculation might not accurately represent the average speed.
The tachymetric scale, a prevalent detail on many wristwatches, is more than just an adornment. It is an engaging tool with a plethora of practical utilities.
It exemplifies the harmonious marriage between aesthetic appeal and practical functionality often found on chronographs.
The In’s and Out’s of Tachymetric Scale
Located on the bezel of a chronograph watch, a tachymetric scale serves as a tool to compute speed based on travel time or even determine distance considering speed.
While initially, it may seem quite intricate, gaining a thorough understanding of the mechanics and principles underlying its operation reveals its simplicity.
How Does A Tachymetric Scale Work?
The tachymetric scale works on the simple mathematical principle of (3600 / elapsed time). The factor 3600 comes from the number of seconds in an hour.
To use the tachymeter, you need to start the chronograph or stopwatch at a starting marker and stop it at the next marker – that could be a mile or kilometer, depending upon the unit of measurement you are using.
For example, if you’re driving a car and it takes you 45 seconds to travel one mile, looking at the tachymeter you would see that you’re driving at approximately 80 miles per hour, based on the position of the second hand.
It’s that simple – the tachymetric scale shows you the speed directly and you don’t have to calculate anything.
Tachymetric Scale and Distance Calculation
The tachymetric scale can also measure distance. This functionality is driven by the mathematical equation speed = distance/time. This means if you’re aware of your speed and the amount of time you’ve been moving, you can easily calculate the distance traveled.
Limitations of the Tachymetric Scale
While tachymeters provide quick and straightforward measurements, they are not without their limitations. They typically work best for events that occur within a 60-second time frame due to the way they are designed.
Tachymeter scales are also limited to measuring speeds greater than 60 units per hour, as the tachymetric scale cannot measure speeds less than that. Lastly, these measurements are typically approximate and should not be used for precise calculations.
Tachymeter’s Historical Significance
The tachymeter has a rich history dating back to the first quarter of the 19th century when Nicole et Capt, renowned watchmakers in London, first used the tachymeter in pocket watches.
However, it was not until the 20th century with the advent of chronograph wristwatches that tachymeters became popular.
