What is a Tachymeter?
A tachymeter is a scale inscribed on the bezel or dial of a watch, designed to measure speed over a fixed distance. It is a functional tool for calculating velocity, particularly useful for professionals like pilots, drivers, or sports enthusiasts. The tachymeter works in conjunction with the chronograph function, offering an intuitive method to convert elapsed time into speed.
How Does a Tachymeter Work?
To use a tachymeter, start the chronograph when passing a fixed point and stop it upon covering a known distance, such as one kilometer or mile. The chronograph seconds hand will point to the tachymeter scale, indicating the average speed in units per hour. For example, if you cover the distance in 30 seconds, the scale might read “120,” representing 120 units per hour.
Applications Beyond Speed
While traditionally associated with speed measurement, tachymeters can also calculate production rates and other metrics, depending on the defined intervals and context.
While tachymeters were initially designed for motorsport and other high-speed activities, they are now popular on many sports or luxury chronograph watches.
