A Tissot watch is more than just a timekeeping device. It is a blend of elegance, precision, and functionality. Among the many features that make a Tissot watch unique, the tachymeter stands out for its practical application and its appeal to those who appreciate both form and function in luxury timepieces. But how does one actually use a tachymeter in a Tissot watch? This guide will walk you through the purpose, function, and practical application of the tachymeter, so you can fully utilize this sophisticated tool.
What is a Tachymeter?
A tachymeter is a scale inscribed around the rim of an analog watch or chronograph, typically on the bezel or the outer edge of the dial. Its primary function is to measure speed based on time traveled over a fixed distance. By definition, a tachymeter converts elapsed time (in seconds) per unit distance (e.g., kilometers or miles) into speed (e.g., kilometers per hour or miles per hour).
While the concept may seem complex, in practice, the tachymeter is straightforward to use and can be a valuable tool for those who understand its purpose. For anyone who appreciates horology and the intricate details of luxury watches like those made by Tissot, understanding how to use the tachymeter can deepen your appreciation for these timepieces.
How Does a Tachymeter Work?
Before diving into how to use the tachymeter, it’s important to understand how it works. The tachymeter scale typically ranges from 60 to 500, with the numbers corresponding to various speeds. When using a tachymeter, the seconds hand (usually part of a chronograph) is the key player. The scale is designed to calculate speed by measuring the time taken to travel a specific distance.
Here’s the basic principle:
If a car travels 1 kilometer in 30 seconds, the tachymeter reading corresponding to 30 seconds (usually 120 on the scale) will indicate that the car is traveling at 120 kilometers per hour.
Conversely, if the car takes 15 seconds to travel the same distance, the tachymeter would show a speed of 240 kilometers per hour.
The tachymeter scale is logarithmic, meaning that as the elapsed time decreases, the corresponding speed on the scale increases, and vice versa.
Using the Tachymeter in a Tissot Watch
To effectively use the tachymeter on a Tissot watch, follow these steps:
Set the Chronograph to Zero
Before you start, ensure that the chronograph function of your Tissot watch is reset to zero. This means that the seconds hand, which usually doubles as the chronograph hand, should be pointing at the 12 o’clock position. This step is crucial for ensuring an accurate measurement.
Start the Chronograph
When you’re ready to measure speed, start the chronograph as the object you’re timing begins to move. This could be a car, a runner, or any other object for which you wish to measure speed over a known distance.
Stop the Chronograph at the End of the Distance
Once the object has traveled the predetermined distance (usually 1 kilometer or 1 mile), stop the chronograph. The position of the seconds hand at this point is key to reading the speed on the tachymeter scale.
Read the Speed on the Tachymeter Scale
Look at where the chronograph’s seconds hand is pointing. The number on the tachymeter scale that aligns with the seconds hand gives you the speed in units per hour (kilometers per hour if you measured in kilometers, miles per hour if you measured in miles).
Practical Applications of the Tachymeter
The tachymeter is not just a theoretical tool; it has practical applications that extend beyond motorsports. Understanding how to use it can add value to your everyday life or hobbies.
Measuring Vehicle Speed
The most common use of a tachymeter is in measuring the speed of a vehicle. Whether you’re driving or observing, you can use the tachymeter to gauge the speed over a known distance. This can be especially handy in situations where speedometers are not available or when you’re curious about the performance of a vehicle.
Timing Events
You can also use a tachymeter to measure the time of various events, such as races or any scenario where time over a distance is relevant. This could be in professional sports, or even for personal fitness tracking.
Calculating Production Speed
In a more industrial setting, a tachymeter can help in calculating the speed of production. For example, if you know the length of a production line, you can measure how fast items are being produced or moved along the line.
The Tachymeter in Tissot Models
Tissot incorporates tachymeters in several of its models, particularly in its chronograph collections. The design and placement of the tachymeter scale may vary slightly between models, but the principle of operation remains consistent. Some popular Tissot models featuring a tachymeter include:

Why the Tachymeter Matters in Luxury Watches
The inclusion of a tachymeter in luxury watches like those from Tissot is not merely decorative. It serves as a reminder of the watch’s roots in functionality and precision. Historically, chronographs with tachymeters were used by racecar drivers, pilots, and engineers, providing them with essential data on speed and performance. Today, even if you don’t use it daily, having a tachymeter is a nod to this rich heritage.
Tips for Using a Tachymeter Accurately
While using a tachymeter is straightforward, accuracy depends on several factors. Here are some tips to ensure you get the most accurate reading possible:
Use a Known Distance: The tachymeter is most accurate when you measure over a known and consistent distance, such as 1 kilometer or 1 mile. Trying to estimate distances will lead to inaccuracies.
Avoid Short Distances: For the tachymeter to be effective, the distance should be substantial enough to allow for an accurate reading. Very short distances can lead to significant errors in speed calculation.
Consistent Speed: The tachymeter assumes a consistent speed over the measured distance. If the speed varies significantly, the reading will only provide an average speed, not an instantaneous one.
Correct Reset: Always ensure the chronograph is correctly reset before starting a new measurement. A slight misalignment can result in incorrect readings.
Exploring Other Complications in Tissot Watches
While the tachymeter is an exciting feature, Tissot watches often include other complications that enhance functionality. These complications range from simple date windows to more complex features like moon phases and GMT functions. Here’s a quick look at some of the additional complications you might find in a Tissot watch:
Chronograph
A chronograph is essentially a stopwatch integrated into the watch, which is often paired with the tachymeter. It allows you to measure elapsed time with precision. Tissot chronographs are known for their accuracy and ease of use, making them popular among sports enthusiasts and professionals.
