Tachymeter Usage

No!  God, no!  

I don't use the tachymeter.  Nor do I ever use the telemeter, nor the pulsometer.  For the very same reason I don't ever use the 600M water resistance on my Planet Ocean.  To me, watches are no longer functional objects - the reason they've become collectibles is precisely because they're useless and anachronistic, just like vinyl records and penny farthings.

But, I will say that it's really fun to time the chronograph hand to synch with the seconds sub-dial at 9 o'clock.  

To me, using a tool watch as a tool would kinda be like commuting to work every day with one of these:

Chronographs are my favorite complication, but I have never had a use for the tachymeter bezel. I suspect that it's included mostly for appearance these days, based on history. One of my chronographs is this Norqain Adventure Sport, which features a rotating bezel, which I personally find more useful, as the bezel can also be used as a secondary timer.

Omega seamaster chrono has a rotating bezel which is even better.

I did once use the Thachymeter to see how accurate was the speedometer in the car... turn out it's a few kms lower in the readings than the actual speed (later confirmed it by using a GPS)

Watches are jewelry. No need to use the tachymeter as my speedometer works just fine. 

I like the chronograph function, never needed the tachymeter. Prefer the Lorier Geminin approach and making the bezel a 12-hour rotating bezel.

Yes.

Long answer, I used the Tachymeter on my Seiko Flightmaster all the time as a teenager in row 3 of a Suburban to figure out how fast my dad was really driving by timing Interstate mile markers.

I also use the slide rule and use my watch as a compass regularly.

Tachymeters are dumb!  

I'll never get one again, as a tachymeter was the only watch I ever had fail on me with water resistance when I turtled a laser (a small sailing boat).  Watch was rated for 100m, I stupidly thought it was literal.  It was a sailing model - so not insane that it would be a couple feet underwater!

I use the bezel function on my divers intermittently: pizza in oven, daughter's time with TV or Ipad, etc..   That and day/date complications are pretty useful - I'm writing in charts at weird times of day and night and loose track occasionally.

Still do lots of water sports - so I now prefer 200m+ of WR for a bit of a safety factor!

I'm headed to work here:

Yes. I've used it to calculate speed and distance respectively whilst doing dead reckoning navigation. Still extremely rare that I use it and only because I can or in extremely dire circumstances while flying.

Was he speeding ? ? 😀

I mean, yes; I should be able to keep a steady pace of eating 375 Girl Scout cookies per hour, which I didn't know before I got my Speedmaster. #thinmints

Its the coolness factor for me, i might have used the chronograph function maybe two times. 

Yes, but actually no.

Yep, only a decoration. Of course when the officer asks ‘do you know what speed you were going?’ you could always look down and say ‘let‘s see . . . ‘ 🤨

I do. All the time. 
I am an engineer and run large computer simulations. The tach scale is SUPER USEFUL to quickly determine how quickly the simulation will finish. 

First of all, congratulation for using the word "anachronistic" 😂.

I second everything the man just said. I collect watches, but i also collect "watch knowledge". Watches characteristics (specs, design, complications) are just more things i can stare at on my watch and appreciate them because i know what it is, how it work, when did it actually serve a purpose, etc... Kind of "conversation starters" but for myself to myself.

I have to admit that i do use my tachymeter when on the highway and the GF is driving, just because i feel like i have to seize the opportunity :p

To be honest before reading this post I had no idea what the tachymeter was for 😂. But I use the chronograph function all the time: exercise, cooking, timing the kids etc. 

Not the tachymeter, I have only have a vague idea how to use it, but I use the chronograph all the time. 

I used the tachymeter once or twice on car trips, just for fun. That kept me entertained for a few mile. 🤷‍♂️

Awesomeness 😂

thats why my collection is mainly GMT and divers
we all need expensive egg timers and who looks at iphones when they are overseas?

I don't even own a chrono, precisely because I don't see myself using its complications. But, along similar lines, I own a watch with a pulsometer scale, and the likelihood of ever using it is nil.

Marc from Long Island watches have a very good vid about it.

Like most of us, I rarely use complications beyond day, date, or GMT.  I do appreciate them and seek out some complications as a connection to the past. I do have watches on which I use the chronograph function as a second time zone. (On watches that have hours and minutes on the same subdial) 

I use it but only for the fun of using the complication on my watch. Similar to it being fun to use the chronograph to time something that doesn’t really matter to you (eg timing the half time break at footy even though you know it’s ten minutes…. Just to use the chrono function and see the dial turn). That said, I don’t measure miles per hour but rather ‘events per hour’….. how many times per hour can my ki do up his shoe laces, how many push ups per hour can I do, how many beers an hour can my friend  skoll….. realising it’s a measure of events per hour, not just miles per hour that makes it more useful imo
