How To Regulate a ETA Powermatic 80 Automatic Movement | SolimBD | Watch Repair Channel

How to Regulate a Powermatic 80 Automatic Movement**
The Powermatic 80 movement, with calibers C07.691, C07.631, C07.611, and C07.141, is a slightly modified version of the ETA 2824-2 movement. While it shares similarities with its predecessor, the Powermatic 80 is more challenging to regulate due to specific design changes.
To ensure accurate timekeeping, regulating the Powermatic 80 movement requires a high level of expertise and precision. Our team of experienced watchmakers is well-versed in the intricacies of this movement and can provide professional regulation services.

Why are you adjusting one screw? You should do the same to the other screw. Can you explain?

[@noodles6929]

Thanks, I understud all already, I just thought that the author was only turning one screw. of course you need to twist both

[@johnraba9322]

Nice video. You did, however, appear to bend the pivot of the balance wheel. Before it spun perfectly. Afterward it began to wobble. You have to support the balance wheel underneath before you use a tool to adjust it. The pressure applied looks like it bent the pivot slightly.

[@SolimBD]

Thanks for the tip!

[@rosomak8244]

And very likely you just ruin the poisoning of the balance wheel. It will then give quite big differences in reading over different positions.

[@mdryfly6450]

Yes! It should not only be supported underneath the wheel, but both balance screws should be moved exactly the same amount to retain it's overall balance. It may take a bit before he notices, or not, but this movement was just damaged quite a bit. That bent and now unbalanced balance wheel will eventually get worse and worse, and wobble more and more, right up untill it breaks off. You can buy an inexpensive L-shaped tool that slips under the wheel and supports it for doing just this, it's well worth it so as not to destroy the movement that you're trying to adjust. These are delicate parts and the slightest bend in any part at all will ruin the movement sooner than later. The time keeping will get more erratic everyday.

[@noodles6929]

if only one screw is adjusted, the balance of the balance wheel will change. Is not it? And as you push down on the screwdriver and balance wheel, the axle can be broken.?

Many thanks for this unique tuto. Well done clear and useful. Thanks to you, I have been able to set my new Tissot Visodate Powermatic 80 as accurately as a COSC movement or even better as it's now at +/- 1 sec/day. Regards. Roberto

[@SolimBD]

Thank you so much

[@ucvietnguyen5876]

All Tissot Powermatic 80 movements have already been COSC-certified, bro. The rate, as ETA (movement maker for Tissot) said, has already been set in their factory with a laser

[@JimmyBlandfood]

@@ucvietnguyen5876 Not true.

[@mdryfly6450]

No they heve not all been certified, not even close. If it says chronometer on it it is indeed certified, however many of these movements are put into non-chronometer watches. Likely more than not.@@ucvietnguyen5876

[@kiseobkim1099]

Thank you for sharing great video. I have a one question. It is fundamentaly same as the Rolex and the Omega. They use timing screw for regulating. It is nessessary to adjust exactly same amount of the opposite screws for keeping poise. Is there no poise problem when you adjusting just one screw?

[@StaticVapour590]

You HAVE TO adjust both sides exactly the same, poising...

[@mdryfly6450]

Yes indeed there is a problem. It is a big issue to adjust just one screw, he wont care for how this movement ends up.

[@watchhans]

You have to regulate BOTH screws EXACTLY the same way. Even 1/100 of a millimeter WILL make a difference. Never do that without a special tool!

[@SolimBD]

Thanks

[@wiktorutracki6469]

Hi! Please help me. This is c07.611. In description you state that this applies to both .1xx and .6xx. I have heard - many times - that the c07.1xx (as oposed to .6xx) is made so that it is not possible to adjust it or repair it and the entire escape mechanism has to be replaced in case of some problems. This is supposed to be due to the escape mechanism being synthetic. Can you tell me what is your opinion about that? I dont know if I should buy a Tissot Seastar it or not. If it is not repairable or any repair of the mechanism would cost me half the price of the watch, I dont want to buy it. I dont know who to trust and you certainly seem to be competent enough.

[@SolimBD]

Thanks for your kind opinion, I would like to say Tissot is a medium category watch and it uses powermatic movement which has 80 hours power reserve, very good quality machine, hope to get good service.

[@Craig_79]

Showing the rate dial up or down does not show poise error which will now exist. Swatch authorised repair centres don’t service these, they have an exchange program in place.

[@carlkim2577]

It's this possible only on the power matic without plastic parts? Ie the higher grades?

[@Mehtabsingh10]

No, the same on both amd can be done with the one with plastic parts too

[@sukiiish]

Thank you :)

[@SolimBD]

Most welcome

[@Visitor555]

Hi, so im about to purchase my first watch with powermatic 80 and from what ive seen its serviceable and watch maker can regulate it easy as you show on this video, but the big question is if something from these new synthetic parts broke it will be less available from normal watchmaker to have it for replacing and then we need to give it to official distributor for tissot to replace it? And do you recommend this movement for long therm use for years? Thanks.

[@lethean1757]

And cannot we change it with another watch's balance wheel system?

[@hapdane5938]

This movement seems to be the powermatic 80 version with 25 jewels, so the escapement is made of metal. The version with 23 jewels has a plastic escapement, but it isn't fragile. It's a relative young mechanism so we can't be 100% sure about its reliability trough decades, but remember that ETA is very experienced manufactor of high quality movements, so it knows what is doing.

[@hapdane5938]

​@@lethean1757 ETA choose a plastic escapement to reduce friction, not to save money.

[@lethean1757]

@@hapdane5938 oh I see thanks for the comment

[@Wildone0687]

Is this pretty much the same movement as the H50 in the Hamilton?

[@SolimBD]

Not same movement but balance is same design

[@mdryfly6450]

Yes it's pretty much the same thing, other than the Hamilton H 50 is a hand wind only version. The balance wheel and it's adjusting screws, as discussed in the video, are exactly the same.

[@echeng5271]

Thanks for the video. It's now clear that it doesn't have a free sprung balance wheel. Weights on the wheel are for regulating amplitude, not beat error. Interestingly, SWATCH claimed that it's a "high tech" escapement with a specific tool for regulation. Now I know the specific tool is a screwdriver. 🤣🤣🤣

[@truespectrum]

It is a free sprung balance - only one side is attached to a stud. By creating a free sprung balance, the length of the balance spring is fixed and the rate is adjusted by tightening or loosening the screws affixed to the balance wheel. The result is that the balance spring breathes better and confers greater accuracy.

[@sagoamicably6486]

the c07.111 has the "high tech" i.e. polymer i.e. plastic escapement on the base level powermatic 80. the .611 and .811 have traditional escapements

[@predragjo5977]

It does require a specific L shaped tool that holds the balance wheel and prevents the balance wheel stud from getting bent. Only then you can use the screwdriver and adjust the screws. What this guy did is he ruined the balance wheel big time by bending the stud. If you pay attention, at the beginning the balance wheel was moving nicely, after he pressed it down with the screwdriver it started to wobble lol. In order to regulate H10 movement you have to either send it to Swatch or find a reputable watchmaker with proper tools.

[@robocopvn]

is this true? there are so many people said the powermatic 80 cannot be regulated.

[@SolimBD]

Can be done regularly but the process is a bit complicated

una pregunta el error es de amplitud y se corrige del volante y de la raqueta mas o menos no

[@MrZZooh]

Don't try this at home guys. Take your watch to a professional watchmaker and have them adjust it for you. The 2824 is fragile enough even with the plus minus levers, let alone this one. Don't do it.

[@mdryfly6450]

Or at least buy the proper tool to support the balance wheel. Not that difficult to do with the proper tools, which by the way are not used here. I have regulated several of these movements with no issues, I do however do it much differently than this. I support the balance wheel with the proper tool, as the hairspring attached to it is very fragile and sensitive, and I adjust both screws exactly the same amount. Just like your watchmaker would do. (assuming that he knows what he is doing)

[@cb1p111]

Lift angle 52 degree at a Powermatic 80? Don't think so! First set your timegrapher right... Then start the work.

[@amenhotep7704]

I checked the tech sheet, they noted they don't even know themselves, can somebody tell me what the lift angle ⁰ is ?

Where is the rotor? Did your remove it?

[@SolimBD]

Yes remove

[@marcelwatchenthusiast5438]

What would happend with results If I choose 53 degree lift angle?

[@watchmaked9467]

This affects the amplitude reading. It will be incorrect by a few degrees or more.

Amplitude 248° ?

How they managed to regulate watches before electronic device era ?

[@accuracychannel.7242]

How do you correct the beat error of a Rolex cal 3135?

[@SolimBD]

Thanks Mahmood Meer I think the same actually. The screws on the ends are to secure the balance with adjusters underneath to adjust the end shake.

[@UnburdenedByWhatHasBeen]

Eta wants you to send your watch off to them for service. There is no other reason for that balance to be designed that way.

[@hapdane5938]

No. All the best calibers made by companies like Omega and Rolex have a free-sprung balance system because it adds more precision to the caliber. It's an upgrade, despite all the rumors about Powermatic 80 that you can read online.

[@UnburdenedByWhatHasBeen]

@@hapdane5938 we'll have to agree to disagree. Ive been working on mechanical watches for long enough now to know that oh though you can be more precise with adjustments on a prespung system, a regulator can be as accurate as a presprung balance. I have chronometer grade watches in my collection with both. Only difference is the regulated movements are easier to service. Eta just as rolex and omega make huge profits from their servicing department. Free sprung is not a huge difference maker in accuracy or reliability like say for instance adding a silicon balance spring.

@@diegocontreras9563yes but regulating means stop the spin wheel, adjust the pin on the wheel a bit, put the wheel back, test again, over and over. The cost will go up significantly, and with much bigger risk of damaging the parts. For the cost of the watches, it is totally not worth it.

[@diegocontreras9563]
