How fast?

I have often looked at the Tachymeter function on watches and wondered if it is at all useful? I am not at all sure how it works ! I did google it and after reading a few articles, or rather trying to read them, my brain hurt. My brain fade is pretty normal but thought I would ask the WC peoples a simple way of using this function?, and what they use it for?

Apologies if previously covered but searching through posts... I have already admitted to my mental difficulties.

Well, at its most basic, it's for calculating the speed it takes to cover a certain length. I have no idea beyond that because I've never used it either.

Nope, it's just for decoration. I'd like one with the pulsometer marks, I can see that could be useful.

My understanding and I might be wrong is you start the timer when passing a mile marker then stop it at the next one and that will tell you how many mph you鈥檙e doing. Why you wouldn鈥檛 just look at your speedometer I don鈥檛 know.

I think this is correct, and I think the answer is because one is in a yacht or horse and buggy or maybe a penny-farthing bicycle, which are contemporaneous to the usefulness of such a device.

It should be noted that they greatly diminish the beauty of any watch.

Speed = Distance/Time.

If you know the distance of the race, the tachymetre will tell you approximate speed.

Thanks I think I actually read this on WC. Good point about the older methods of transportation, I keep forgetting the history of some complications.

I kind of like the look of a tachymeter in some cases, like on my Mido I think it adds a bit of depth.

Of course I like a busy dial which helps.

A tachymeter is useful for calculating ANYTHING per hour - how many bows you can tie in an hour , how many cards you can sign in hour, how many miles or kilometers you can travel per hour. Time one event on the scale, and it shows you how many you can do in an hour (which is why 鈥60鈥 is at the 1 minute mark).

I use my tachometer often; I love its functionality.

It's a conversation starter on your wrist because any real timing is done on a digital down to a 100th by any 20 dollar Casio digital. It's from your grandfather's era kinda like a slide rule. Most here will have to google that last one as it's so old.

Exactly, the number on the scale tells you how many 鈥渋nsert what you want to measure鈥 you can do in an hour.

It was particularly useful in race tracks, because they鈥檙e not straight, so the tachymetre tells you your average speed on one lap.

Because you could tell your average speed on any track (give you know it鈥檚 length), the speedometer only tells you the speed you鈥檙e going at that particular moment.

Of course it鈥檚 now rendered obsolete, but back in the day it was very useful.

Doesn't

It can be used to measure speed and also distance. For giggles I even used it to calculate the average wait time for my customers at work and came up with an average of 28 customers per hour. Lol, I鈥檓 gonna try & hit 30 next time

Hadn鈥檛 thought of that, but it makes a lot of sense. 馃憤

That鈥檚 exactly what it鈥檚 used for, mainly.
