Lesson: Part 2 - Removing Balance


Recommended Posts

I've watched again (and again) the lesson from Part 2, section on stripping the movement, video on Removing the Balance. I noticed that Mark, having taken the balance out of the movement put it on his workbench where it was supported by its lower pivot! He next lifted it and put it down properly flipped on its cock.

Is this the recommended way to do it? Isn't it dangerous to put balance wheel, with all the weight of the cock, down on the (lower) pivot? Am I worried too much?

I havn,t seen the video.

What breaks a pivot is impact ( a shock).  

Not only the weight of a cock, not even  the weight of the whole movement or the whole watch,  would not damage a pivot if gently place on pivot.

It is like trying to drive a nail into wood by pushing on it as hard as you can, wont do any good. While hitting on it's head with a hammer would drive the nail in. Push is force , hitting with hammer is impact ( shock) . 

This is a subject of basic dynamic.

Regards

I usually pick it up out of the movement and flip it around right away or hang it from the balance holder from the cock (name change needed:)

usually i use a balance tack but i only have one so if i have an extra balance iam working on i place it with bottom pivot down on a piece of rodico. i dont like flipping balance over because i always grab it by the cock, unlike mark how he grabs the cock and balance together. i guess its a matter of preference. placing it briefly on the desk like mark did will not cause any damage to the lower pivot though.

I usually grab the balance cock and then hold the cock and balance in my hand and then flip it over. Btw if this were not a watch repair blog and someone were to read what I just said, the site could be shut down:)

Make sure the upper pivot is out of the jewel if you grab the cock and BW togther and you are not squashing the HS. The BW is not to be actually grabbed rather the wheel hangis on tweezers.

    • in general this shouldn't be any change. but in general questions like this it be nice to know the specifics of the watch in other words how was it performing before it was cased up and what is it doing now.
    • just as a reminder this watch is a Swatch group product. This will bring up a problem like spare parts and technical information. that I found some links to some information on when I talk about your watch and some of the technical and basically your watch is equivalent to 2834-2 for which I'm attaching the technical sheets. But equivalent does not mean exactly the same you want to do a search on the group for C07 as we discussed this watch before including the technical differences how it's supposed to be regulated and basically because it's watch group there is no parts availability. https://calibercorner.com/eta-caliber-c07-xxx/   https://www.chrono24.com/magazine/eta-movements-from-the-2824-2-to-the-powermatic-80-p_80840/ https://www.watchuseek.com/threads/h-10-movement-details.4636991/ eta CT_2834-2_FDE_481857_15.pdf
    • people be honest.... Swatch is evil for the watchmakers and repairers, BUT not everything in watches from Switzerland is from the Swatch-Group. As far as i know, Selitta got sacked by Swatch as a Movement-Assembler for them and they started to produce Movements in their own Name with slight Modifications. As far as i know, they sell Parts to the Market for their Movements. In most cases, if a ETA-Movement fails, it is a valid Option to replace it with a Selitta Movement, which i consider the Solution for this Mess with the Swatch-Group...... I have no Connection to anybody at Selitta, but being a Swiss-Guy, i still like to have Swiss-Made Watches, but not from the Swatch-Group.   ok ? regards, Ernst
    • Just one more greedy act by Swatch. They started a number of years ago here in the US..cutting off supplies to watchmakers that could build complications that many Swatch houses couldn't even touch. Old school masters who had gone through some of the most prestigious houses in the world. Otto Frei has some statements on their page about it. I tell all my customers to avoid new Swiss watches like the plague,..unless they just want an older one in their collection that still has some parts out on the market, or they have really deep pockets and don't mind waiting months and paying through the nose to get it back. Plenty of others to choose from..IE Seiko,..or other non-swiss brands Even a number of Chinese brands are catching up with the Swiss,..and I think that in time, their actions will be their downfall
    • Yes. If that's not what you are experiencing...start looking for something rubbing. A 1st guess is that one of the hands is rubbing against the hole in the center of the dial. Especially if you now have lower amplitude in face up/ face down positions.
