Right now I am currently working on a Venus 188 but the driving wheel that sits on the extended pivot does not fit. The hole is too big. I had this problem with a tissot 27-621b too. I ordered a new part for the Tissot but is there an effective way to crimp these holes so I dont have to spend loney on replacement parts. 
If not, something i can fill the hole with and then ”make a new hole” with a broach that fits nicely?

 

thanks for any help!!

A slight tap with a rounded punch on the bottom side of the bore will close it enough for a tight seat (usually).

Agreed.  I would expect the rounded punch to be of significant nose radius and diameter in comparison to the hole your trying to shrink.  I feel you will get better penetration of your efforts, and straighter hole.  You may still be required to fit the parts to each other afterwards.

Best of luck.

That sounds like a great idea!

thanks for the help. I am just getting a staking set as well so it will be perfect!

    • 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.
    • Once a movement has the dial and hands put back and it is recased, would you expect the assembled watch to have the same amplitude as when the movement is in a movement holder and is without hands and dial? Thanks
    • C07641+ not sure what the "+" is for after the last digit.
