How To Use A Tachymeter On A Watch

Many of my viewers have asked me how to use a tachymeter scale on a chronograph watch
I give 5 examples in this video to demonstrate that anyone can use this effective tool in everyday life.
Feel free to leave your comments and input

[@nickmcfarland6822]

As an American, I was lost on Km/h, but once the hamburger analogy came out, I was in.

[@avrankulj]

I feel bad for the kid having his hamburger timed by a boss wearing an Omega

[@PeterKotsa]

Haha..that kid needs to get his act together 😂

[@sstewart82ss]

😂

[@robinrobson5363]

Get a Breitling! If one desires to own a chronograph one should own a chronograph by a company devoted to chronograph movements years ahead of other watch companies. Breitling, instruments for professionals.

[@vilhamdutch2962]

My thoughts exactly

[@kkrsnn5632]

That's why the boss is boss and he has an Omega 😜

[@samsonstaats3851]

On behalf of everyone who’s seen this, thank you for such a descriptive and easy explanation of an awesome tool.

[@PeterKotsa]

My pleasure cheers

[@mwendwamunene538]

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.

[@jerichowatches1]

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.

[@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 🤔

[@robinrobson5363]

Oh, well do not tell Formula 1 or the pilot's association!

[@heathwasson7811]

@@robinrobson5363 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]

@@heathwasson7811 And assuming that the GMT function is actually easy to use because some GMTs are kinda of a headache to remember how to read them

[@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.

[@JO-vs5bx]

I am a veterinarian and I use this to measure the pulse of several animals. amazing tool

[@benmurray1902]

Been staring at my Seiko with the Tachymeter wondering, "How the heck to work this ?" This video makes me stop staring blankly and increase my staring productivity on my watch!!

[@IsaiahTrollenberg]

Staring productivity is very important!

[@michaelcorvin4330]

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)

[@baba.mkhulu]

over the last 50 years...& with all the chronos i've owned...i thought it was some gadget for divers that just looked cool. so i learned something new today. 🙏🏽

[@dfb1976]

Wore these in my teens and 20s never knew what they are for. Just found it cool to show off.

[@1crans1]

Absolute great way to explain how a watch works.....just bought a watch after 40 odd years without one and thank you

[@daynevickers1079]

Great explanation... I just purchased a Chronograph watch because I loved the way it looks. I am thrilled to know I can actually use it to time my efficiency at things like preparing burgers or determining the average speed of a car in case my speedometer breaks. 🤣

[@fteambjj]

Those guys who work at a burger joint when they see their bosses wear a chronograph watches be like 😶

[@PeterKotsa]

hahaha..nice one :)

[@robo2606]

😂

[@h.albertmayorga5522]

Yeah 😂

[@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 👍

[@kevint3845]

Really excellent video, ive owned watches like this for ages but never had them explained so well.

[@dmarti47]

This is awesome. Thanks for explaining this so clearly and with several easy-to-understand examples. Indeed, these watches are tools and we need to use them to their fullest potential.

[@carpentersson77]

Exactly.

[@benorex8980]

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

This watch feature has been a mystery to me for a long time. Thank you for making this video and explaining how to use this feature.

[@michaelniemer4449]

So simple, but I never thought to use in reverse with a constant speed to verify distance traveled, fantastic! And then the burger assembly example, time for lunch!

[@vikrampitre2343]

Wow ! Your simplification by practical examples , what a job .

[@fcllyvr3000]

Peter, thank you for this info in your video. I finally now understand what a Tachymetre is and does. Both my Tissot and my Citizen eco drive has the Tachymetre scale....

Very imformative. I thought I knew what I needed to know about the tachymeter before I watched the vid. I'm going to have to watch this again a couple of times to feel fully educated.

[@davezdgalmancornelius6388]

I didn't even know what it's called before this. Thanks for this one. Really helpful.

[@thisiserich]

I’ve never thought to use a chronograph in some of the ways you explained. Great video!

[@mhzprayer]

I love that the units don't matter. I could be traveling at 120 hamburgers/hour and as long as the pilot doesnt account for deceleration, we know it will take 22.5 minutes to catch Ussain Bolt. That is amazing!

[@ninhful]

Thank you. I have been looking for the answer since long time. Even watch shop employees couldn't give me satisfactory answers. Some do specialize more on selling.

[@Walty03]

The key is one single Unit of your choice, but it has to be constant single of the unit desired. Excellent video!

[@PeterKotsa]

Thanks Armando, glad you liked it! Cheers

[@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.

[@pchatterjee4150]

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!

[@j.aditya7117]

[@atifasadkhan]

I have learnt something new today!! thanks Peter!!!

[@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.
