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.
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

Armitron watches have a wide range of costs depending on the type of watch you are looking for. They range between $20 to $200, the average watch costs around $100.
The best place to buy an Armitron watch is at a male jewelry outlet. For example, Barneys sells expensive watches, as does Amazon. To find the best watch you must go to a jewelry outlet for men.

When I purchased this watch the wrong direction were in the box. My grandson really likes this watch. It's a Armitron Digital WR165. Please help.... Shelly Holverson, Freeport, IL.
Looks like Armitron Men's Square Black Digital Sport Watch (408115BLK)
If you buy their more expensive products (in other words, those typically found at prices greater than $50.00 list) I'd say they're very good. I bought an Armitron digital/analog watch in the early '90's to serve as a back up watch when the batteries would go out no my Seiko (which cost nearly 5 times as much). The Seiko, which was my daily watch for nearly 20 years finally died, but the Armitron is still running. Granted, it hasn't been subjected to the abuse and day to day use the Seiko did, but the fact that it's kept running, needing only battery replacements and no servicing says something. The watch also keeps very accurate time, losing about 5 seconds/month. This back up Armitron that I bought originally listed for $59.95, but it was a close out when I bought it and got it for $39.95. I had another Armitron prior to the Seiko and the later "back up" Armitron, and it was great as well .... until it fell into the Atlantic Ocean (hardly Armitron's fault!!). I wouldn't hesitate to buy one of their better quality pieces at all.
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.
Well they always say "America's Watch" so I would think America BUT if it says China then it was probably made in China for Armitron, which most people wear in America.
China is where the watch is assembled. The movement might come from one place, the strap from another, but it's all brought to China for assembly.
That means it was made in China.
