A tachymeter is a scale which measure speed. It does this by is located on an a analog watch. They can be purchased from any store which sells watch supplies
A tachymeter on a watch is used to measure speed based on time and distance traveled. By timing how long it takes to travel a known distance, the tachymeter can calculate the speed at which the distance was covered. It is commonly used in racing and sports watches.
The tachymeter will tell you how many times something will happen in one hour. For instance, if you time a car going around a one mile track, the tachymeter will tell you that the car was traveling at X mph. If the track is only a half mile, then divide by 2 to get mph (and etc. for other distances). You can use it to tell how many times any event happens in an hour. Time how long it takes for a machine to produce 1 widget and the tachymeter will tell you how many it makes per hour. It can also be used to compute distance if you know your rate of speed. Say you're on a plane that you know is travelling at a constant 400 mph. Start timing at one point and stop when you want to know the distance. If your tachymeter stops at 100, you know you've traveled four miles. 400 mph/100 = 4.

Using a graduated ruler, a surveyors wheel or trundle wheel, or by using an optical (Tachymeter) or laser range finder are methods that may be used to find length or distance.
To measure the average speed of an object over a set distance. You must know the distance between point A and point B. But, if you don't have a watch with a tachymeter/tachometer function, you can find out speed over a measured distance if you simply know how to divide and convert.
when theodolite is fixed with analytic lens then it is called tachometer, without the analytic lens the instrument would be called as constant zero.
Common watch functions include telling the time, tracking the date and day of the week, displaying a chronograph for measuring time intervals, incorporating a tachymeter for calculating speed, offering a moonphase display to track lunar phases, and providing water resistance for underwater activities. Additional functions can include alarms, world time displays, and built-in compasses.
