The most common calculation scale system in chronographs is usually located on the outermost part of the dial or on the outer ring of the case. A chronometer is an instrument or instrument that tracks and records the elapsed time. It is usually displayed in hours and tenths of an hour. Many hour meters are used to record the running time of the equipment to ensure proper maintenance of expensive machines or systems. This maintenance usually includes replacing, replacing or checking parts, belts, filters, oil, lubrication or operating conditions in engines, motors, blowers and fans, to name a few.Subtotal 1 is the time spent in the car in the last two hours. Subtotal 2 is the total time spent using the car in the last two days.

The main principle is: given a certain unit distance, such as 1 km or 1 mile, when a moving object starts moving within this distance, start the start function of the chronograph. When the unit distance is completed and then press the stop button, the speed of the object is the scale indicated by the pointer. If the calibration system is of single turn design, the speed of the object is less than 60 kilometers per hour, and the code meter is invalid; The code watch with spiral scale will not encounter the watch with stopwatch function. The outer ring of the watch will be engraved with 500 / 400 / 350 and other decreasing numbers. These represent the physical quantity of speed, and the unit is km / h; This ring is called tachymeter.

For example, a car has a fixed average speed of one kilometer or one mile. Take the speed measurement method as an example. When the car moves forward with the mileage mark on the roadside as the reference point, start to activate the timer. When the car reaches the next mileage mark point, the timer stops, and the position where the timer pointer stays on the speedometer scale is the speed of the car. If 1000 meters is used for 45 seconds, it can be converted to the running speed of 80 kilometers per hour.
