Very educational video thanks !!!

i tell you there is something almost mystical about watch movements...unfortunately i cant afford something like this! see kids get a career worth a shit!..so u can buy cool toys!

[pballerbiedermann]

actually gruoble forsey has proven that the tourbillion does in fact inhance the accuracy of a mechanicle watch

[aimtrue45]

If only I could afford one!

[heliman29]

The point is... accuracy in a "mechanical movement". Pretty cool when a small watch with 200 some-odd moving parts can be accurate to within a few seconds a day.

[assa123assa123]

it is well proven now that tourbillon doesn't increase accuracy. It is merely an eye-catcher and a complication or a kind of a funny mechanical work. Mechanical watches are not about accuracy anyway. And even those -4 +6 do not always perform that well and do break, surprisingly.

[heliman29]

What do you mean the Tourbillon doesnt increase accuracy assa123? Don't say "it's well proven" when you're just pulling that out of your backside. It virtually solved accuracy issues with pocket watches which is what it was intended to do. Is the functionality of a Tourbillon necessary? ...No. Do they improve accuracy by canceling out the differential rate of gravity? ...of course it does! granted a wrist watch needs an off-axis or 360 tourbillion to accurately compensate effectively.

[assa123assa123]

I used not only my backside, but wikipedia research also. And I think (and they said it there too) that poor performance of pocket watches at those days was NOT because of gravity, but because of bad escapements and tolerances and also neglection for the need of thermocompensation. And when I say doesn't improve I mean it is questionable and certainly not a step up. Please read wikipedia on tourbillons, they say reasonable things.

[heliman29]

Are you referring to the "any imbecile on the planet can contribute wrong information" Wikipedia? Oh yeah thats a good place to get your information. You definitely don't want to count that THAT dingo site to settle a point. Yeesh. Listen, the bottom line is that the regulator pin is what functions to adjust accuracy. Regulate the watch with a tourbillion ON and then turn OFF and youll get different times. Reverse the operation and youll achieve the same odd resultso which was MORE correct?

[assa123assa123]

sorry, I don't get your point =) I find wikipedia a good source and trust it in many subjects. and I think we have drifted away. Do you not agree that tourbillon is a fashion and prestigious point rather then technical element? Is tourbillon accuracy unachievable in plain lever escapement mechanics? Can tourbillon compensate for strong shakes and balance amplitude changes related to them? What can it do about high spring to low spring reserve balance rate change?

[heliman29]

You trust Wikipedia? Okay...?

The Tourbillon escapement wasnt designed to absorb strong shakes or anything else you mention. However yes, its a fashion/prestigious point rather than a necessary element. Mine is accurate to within +2 a day but that can be changed at the adjustment pin anyway. However, any mechanical movement I own will result a different time over 24 hours by a few seconds depending if I lay it on its crown side, or opposite side. There is zero change with the Tourbillon.

[assa123assa123]

So it is - one side or another, right. But when on a wrist it often changes many positions in different planes and with shakes and sudden changes.

And anyway, as I prefer vintage manual winding watches I rarely use one more then two days, usually one day in a row. So accuracy is not the point for me. I don't set them to seconds =)

[heliman29]

Are you asking me to pick a side? It's both, your original statement is that the Tourbillion doesn't affect accuracy... it does. It's a status symbol too. You also say the Tourbillon runs into trouble when worn on the wrist... that's the point of this video. It's off-axis to compensate for those movements. Have you seen Jaeger LeCoultre's Gyro-Tourbillon? Wow, very impressive piece of mechanical engineering to say the least...

[PatientZeroThree]

You are correct on all points heliman29.

[lolcat23]

@heliman29 however, a tourbillon should be very shock resistant. it is after all a rather(comparing weight with size) strong steel construction only holding a few grams of weight, rotating on rather big and strong pivots(unlike the balance, which is held on tiny pivots). Biggest risk is breaking the jevels that hold the tourbillon in place.

[lolcat23]

@assa123assa123 There is a reason why most companies only do 5 position testing of their movements. gravity does have an effect, and tourbillons do diminish the effect it has on static or semi static positiions of the watch(thus the effect a tourbillon has on a wristhwatch is less then on a pocket watch).

However, 1% of the reason why a tourbillon is in a watch is because of accuracy gained, that i will grant. But i refute that the effect is zero. it is very noticable.

[glazba]

This is brilliant. I'd love to see on in the flesh. I'm not sure why people are moaning about the relative merits of accuracy. If all that matters to you is accuracy, then you're looking at the wrong technology altogether.

[bakkendorff]

Not really. In a time before quartz watches, and atomic watches, mechanical watches were the only way to measure time, other than celestial observation(which were quite unhandy!)

But in the modern watch mass market, where 99% as marketing and 1% is craftmanship, you are spot on! :) But today, true craftmanship from guys like Greubel Forsey, Dufour, Andersen and so on, are extremely expensive!

[nathantw]

Well, yes. All tourbillon watches are for show since the arm it's attached to acts like a tourbillon so it's unnecessary. It was important for pocket watches though.

[WatchCommander25]

However, pocket watches are no longer important so the whole concept is out the window.

[zloben9000]

thats dumb !

its just a SHOW. does not make the watch more accurate.
