How To Use A Tachymeter On A Watch

Brilliant explanation of how to use a tachymeter. This video has motivated me to get myself such a watch. Kudos

[@omerozyer9061]

Thank you for this useful and beneficial video regarding tachymeter. There is only one thing; To complete 1 mile distance in 28 seconds, our speed will be 128 miles/hour not 128km/hr.

[@BLUETOOTH48]

Yeah I've just bought a Pagati moon watch so very helpful 🙂

[@JasonFisk]

What he said. I've had Tachymeters on watches for years, thought they looked cool, never knew how to use it. Until now. Thanks, man.

[@BadGuyDennis]

Tachymeter can also be used as a pulsometer with some conversion. Once you feel a pulse, you start the chronograph function. Count for 30 pulses (the starting one count as zero). Then stop the chronograph. By dividing the tachymeter reading by 2, the result is pulses per minute.

[@PeterKotsa]

👍

[@UNSCPILOT]

A good multiperpous function to be certain, low tech, but effective

[@Mikesmeyer88]

Great now I have to buy one, even though my phone can do that.

[@ahsanabir2902]

How stupid can you be !! you have counted beats for 30 seconds, just multiply by 2 , and you get beats per minute.Useless fellow .

[@gilean6179]

you just need a second hand...count the pulse for 6 seconds and multiply by 10; that is it. did that for several years in med school...unless you are instructed to take the full minute on certain medical conditions.

[@Bob.martens]

Tachymeters went the way of the divewatch: many people own them, professionals stopped using them decades ago, and not that many people actually still know what they really used to be for.

[@PeterKotsa]

I agree, most of my friends don’t know how to use them either 🤔

[@heathwasson7811]

@Robin Robson Pilot here... and AOPA member. No matter how well we my like the style, none of us actually use any pilot watch functions for anything other than basic time telling in the cockpit. GMT is about the only useful thing for pilots, assuming you're traveling international a lot. I actually use a chono and diver's bezel a lot, but mostly in the gym timing sets, or the kitchen when I've got multiple things going on the stove.

[@vaggelisdogas]

Well the divewatch function can be somewhat useful on a daily basis if for some reason you dont have a timer available,such as exams.

[@vaggelisdogas]

Also works on distances longer than 1. Multiply the timed result by the track distance. Example: Daytona International Speedway's oval course is 2.5 miles. If a car completes one lap in 45 seconds, the result would be 80. 80 x 2.5 = 200mph average speed.

[@markymarknj]

THANK YOU!

[@romrig4648]

How is that any better than Distance divided by time? Tachymeter is designed to show the speed you go at with a single look, not to do math :/

[@michaelcorvin4330]

@@romrig4648 I was simply pointing out courses over one mile, kilometer, or whatever metric you are using. Plus, the tachymeter shortens the equation from distance/time X 3600 in those longer than one situations.

[@yoyoezzijr]

Yeah, because speed = distance/time. tachymeter scale = 1/time (in hours) So distance x scale = distance / time (per hour)

[@martinkaloki2677]

This is brilliant! The explanation is so simple yet it still hits home.

Very well done! I’m a glider pilot and i just got myself a watch with a Tachymeter so your video was extremely helpful. Thanks mate and cheers

[@PeterKotsa]

You’re welcome 🙏

[@beru58]

You can use it to check your pulse. Say "nil" when you start the stopwatch. Count 60 heart beats and read your pulse in plain text. (If your pulse is higher than or equal to 60 bpm that is.) But you never do that. You count 15 heart beats and devide the reading by 4.

[@jono8884]

Great stuff, we almost never used the tachymeter for anything but its looks so understanding its tool usage is nice. Like a slide rule, the more you use it the more it will become familiar.

[@PeterKotsa]

Correct 👍

Dude, all these years I've had fancy watches & cars and didn't think about the topics that you have explained in the video. Thank you for adding to my knowledge.

[@PeterKotsa]

welcome bro..👍

[@markopolic9964]

Fantastic explanation! Please note that the speed calculated in example 1 is still the average speed of the car over 1km. If the car doesn't decelerate nor accelerate, then the current speed = average speed, but the read speed is still average. If the time passed from starting to stopping the chrono was very very low, then it would be the true current speed. Otherwise, great explanation 👍

[@PeterKotsa]

[@edmundchiang]

Thanks for the excellent introduction. Just a remark: speed as shown in any speedometer always represents an average speed, or average velocity in physics term. You need to have a distance travelled against the time taken to calculate a value “speed”. That is, distance travelled per unit time. That is why Newton’s “instantaneous velocity” (speed in “no time”) is so contradictory and so difficult to understand (probably no one can really understand still) ...

[@PeterKotsa]

👍😎

[@BIoodBath]

In physics terms it would still be "average speed." Velocity implies speed + direction. Instantaneous velocity is change in position in "no time," not speed.

[@bmjames]

Instantaneous velocity gives you the hypothetical direction & speed that something would continue to travel at, if it immediately stopped changing speed or direction. To put it in car terms, let's imagine you are cornering, when you suddenly hit a perfectly frictionless ice sheet and lose all grip. Your car's centre of mass would continue to move in a straight line, at the direction and speed it was going when it hit the ice. The instantaneous velocity at any point in time is the hypothetical ice sheet scenario at that point.

[@edmundchiang]

@@bmjames you can use the current D-modules theory/language to deal with derivatives. The formal symbolic calculations setup is essentially what have been known as operational calculus from the 19th century, which is the rationale behind Heaviside’s calculus and most probably operational methods behind Ramanujan’s calculations. You can find recent attempts by G.C. Rota about rigorous approach on umbral calculus. But the D-modulus is a much better language.

Explained brilliantly😊. Excellent presentation.

[@sopapillas6398]

Thanks for the explanation! Quick correction though, it would be the average speed. In a perfect world, the car isn't accelerating or decelerating, but in reality that doesn't usually happen. So calculating speed over a distance based on time would end up as an overall average speed.

Awesome video! Very well explained. I am enjoying each and every video from the time I subbed ; I like your way of explaining different features or functions that has anything to do with watches, something very different from most KZbinrs who who simply review a watch and tell stuff, we mostly know, but still watch it to get a good idea of how the watch's going to be in flesh. I would appreciate a video on explaining in simple terms what makes the expensive watches expensive and uncovering some mechanical / automatic movements right from the basic movement. Another video may be on how to understand which watch will retain most of its value, given that as collectors we feel the constant temptation to keep buying one after another. Keep up the great work mate!

[@williamjensen365]

Most U.S. highways have mile markers. Unfortunately, tachymeters only work at speeds over 60. More practical for kilimeters than miles. A friend of mine used to have a Seiko with a tachymeter that "wrapped around" up to about 70 seconds. Worked better on roads with the old 55 mph limit.

[@benjackson6260]

There are only 60 seconds on a watch.... Soooooo... How the 70 sec wraparound...??? 👀👀👀

[@WreckedRectum]

@@benjackson6260 Easy, you just divide the time to get it within a minute and then divide the unit by the same amount. If you use 70 seconds to drive 1 mile, you can divide the time by two and read the speed and divide that by two as well. For this example you'd take 70/2=35. The indicated number on tachymeter scale at 35-sec mark is about 102, so that's 102/2 = 51mph. If you're biking, for example, and it takes much longer, say, 2m30s to complete one mile (that's 150 seconds): Divide 150 by 3 to get within the 1 min range, read the tachymeter scale and divide by 3 there as well; 72/3=24mph. You can measure anything per hour (or minute with some simple division) with a tachymeter scale, no matter how slow or fast. Last one I used was yesterday, number of golf balls shot on the range per hour. Before that my daughter wanted to know how many grey cars we would pass in an hour (way too many. We need more colours in the world.)

[@benjackson6260]

@@WreckedRectum I am not gonna lie... I really needed to read all that u said twice... But I got it...Its absolutely amazing... How u can measure almost anything no matter its nature or use using a series of numbers... It really makes u think that calculating everything around us in numbers is indeed possible... Like how many birds fly above someone's head per day, How many strangers he sees, What common words do people say around him... And replicate that to form a complete simulated world in which a real human could never find that its not real... It makes u think that maybe it's us who is making these hypothetical futures like Terminator and Matrix easier to achieve for the machines (if indeed such a thing does happen)...

Good question 🤔

[@aileenfarrol2158]

I will now.

[@ylihao]

Thanks for the explanation. I feel the fact that you need to have known some of the parameters beforehand for this to be useful makes it rather impractical in real life. Say at a random stretch of road, you wouldn't have markers with a known distance, unless you prepare and measure it beforehand, without the markers the tachymeter would be useless. And how often do you have vehicles that travel in constant speed in real life? As for the hamburger example, since the tachymeter scale and the corresponding seconds are always constant, a timer and a picture of the tachymeter scale would do the job, you don't really need a watch with a tachymeter scale for that matter.
