The chronograph offers a variety of functionalities beyond basic timekeeping and stopwatch functions. One intriguing feature found on many chronograph watches is the tachymeter. This is not a separate dial, but rather a specialized scale often etched along the outer rim of the rotating bezel. The tachymeter transforms your chronograph into a tool for calculating speed.

How Does it Work?

The tachymeter works on the principle of speed = distance/time. It consists of a marked scale calibrated for a specific distance, typically one kilometer or one mile. By using the chronograph function to time a moving object over this set distance, you can calculate its speed using the tachymeter scale.

Utilizing the Tachymeter:

  • Start the chronograph (chronograph function) as the object you want to measure the speed of begins moving past a fixed point.
  • Stop the chronograph (chronograph function) once the object travels the known distance, such as one kilometer marked on a road.
  • Align the chronograph seconds hand (chronograph function) with the tachymeter scale. The number on the scale closest to the tip of the seconds hand indicates the speed of the object in units per hour (for a 1km scale) or miles per hour (for a 1-mile scale).

Applications of the Tachymeter:

While not as precise as modern electronic speedometers, the tachymeter can be a useful tool for:

  • Racetrack enthusiasts: They can estimate lap times or car speeds.
  • Athletes: They can gauge their running or cycling pace over a measured distance.
  • Boaters or pilots: They can use it for rough speed calculations in emergency situations.

Beyond Speed:

The tachymeter's versatility extends beyond measuring speed. With some calculations, it can be used to determine other rates such as:

  • Production rates in manufacturing
  • Heart rate during exercise (using distance traveled by a runner and the time it takes to cover that distance) 

Important Considerations:

The accuracy of the tachymeter reading depends on precise timing using the chronograph function and an accurate measurement of the known distance.

In the next section, we'll delve into the world of chronograph complications, exploring additional features that elevate these timepieces beyond basic timekeeping.
