One of the most famous and popular watches in the world is the Omega Speedmaster. The iconic chronograph watch used by NASA astronauts has become one of the most recognized timepieces globally and has inspired countless watches with a similar appearance. One of its most prominent design elements is its bezel. Over the years, Omega has changed the materials used for this bezel, incorporating materials such as stainless steel or ceramic alloys. However, one thing has remained unchanged for many years—the Tachymeter scale displayed on the bezel of the watch. In this article, we will get to know a little more about tachymeter watches, understand what a tachymeter scale is, and how it is used.


What is a Tachymeter?

A tachymeter is a scale on the outer edge of a watch's dial or bezel that allows users to measure speed over a known distance. It is typically calibrated in units per hour or units per minute. By using the tachymeter scale in conjunction with the watch's chronograph function, one can determine the speed of an object or the time it takes to cover a particular distance.


History and Evolution of Tachymeter Watches

The concept of tachymeter measurement can be traced back to the early 20th century when watchmakers started incorporating this feature into their timepieces. Tachymeter watches gained popularity in the 1960s and 1970s, primarily due to their association with motorsports and the increased demand for accurate timekeeping during races. Over the years, advancements in technology and design have led to the development of more precise and aesthetically appealing tachymeter watches.


Measuring Speed with Tachymeter Watches

Tachymeter watches offer a practical and efficient way to measure speed. With their built-in scales and chronograph features, these timepieces provide a valuable tool for various activities that involve speed calculations. Here's a breakdown of how to measure speed using a tachymeter watch:

  1. Understanding the Tachymeter Scale: The tachymeter scale is typically located on the bezel or dial of a tachymeter watch. It allows you to calculate speed based on the time it takes to cover a known distance. Familiarize yourself with the markings and increments on the scale to accurately measure speed.
  2. Activating the Chronograph: To measure speed with a tachymeter watch, activate the chronograph function. The chronograph is a stopwatch feature that enables you to measure elapsed time precisely. Learn how to start, stop, and reset the chronograph on your specific watch model.
  3. Starting the Measurement: Begin by selecting a known distance to measure. For example, if you are timing a car's speed, choose a mile or kilometer marker. Start the chronograph as the object being timed passes the starting point.
  4. Timing the Interval: As the object reaches the endpoint or a specified distance marker, stop the chronograph. The elapsed time will be displayed on the chronograph subdials or digital display of your watch. Note the time value for the measured distance.
  5. Reading the Tachymeter Scale: Using the recorded time value and the tachymeter scale, determine the speed. The tachymeter scale is calibrated to indicate speed units per hour. Align the recorded time value on the tachymeter scale and read the corresponding speed directly.
  6. Interpreting the Results: The speed displayed on the tachymeter scale corresponds to the speed at which the object traveled during the measured interval. For example, if the tachymeter indicates 120, it means the object was traveling at 120 units of speed per hour.

Remember, tachymeter watches are versatile tools for measuring speed, but they are most accurate for activities with consistent and linear motion. Practice using your tachymeter watch to improve your speed measurement skills and make the most of this handy feature.


Popular Brands and Models of Tachymeter Watches

Several renowned watch brands offer tachymeter watches, each with its unique design elements and features. Rolex, Omega, TAG Heuer, and Tissot are among the brands that have incorporated tachymeters into their watch collections. Models like the Rolex Daytona, Omega Speedmaster, and TAG Heuer Carrera have become iconic timepieces known for their precision, craftsmanship, and association with motorsports.
