Tachymeter Complication Used in conjunction with the chronograph, a tachymeter scale allows for calculations of speed over a fixed distance. The tachymeter scale functions independent of the unit of distance, i.e. miles, meters, etc., provided the unit stays constant for all comparative measurements. For example, a vehicle crosses the start line and the chronograph is started. One mile later when the vehicle crosses the finish line, the chronograph is stopped. The chronograph hand will be pointed at the amount of elapsed time between the start and stop points. The corresponding number on the tachymeter scale where the chronograph hand is pointed reveals the average units per hour at which the vehicle was traveling. In this example, the chronograph hand ended up pointing at 9:00 meaning 45 seconds elapsed which corresponds to approximately 80 MPH on the tachymeter scale.
