A tachymeter watch allows you to measure speed based on time and distance. Found on the bezel or outer edge of the dial, the tachymeter scale works in conjunction with the chronograph function. To use it, start the chronograph when passing a fixed point and stop it after traveling **one unit of distance** (e.g., one mile or kilometer). The chronograph's seconds hand will point to a number on the tachymeter scale, indicating the speed in units per hour. For example, if it takes 30 seconds to cover one kilometre, the tachymeter will show 120, meaning you’re traveling at 120 km/h
