Re-jewel or resize pivots?


Recommended Posts

After a years hiatus from my watch project(renovated house after tenants from hell) I find I have to put in my third balance staff. This is on my 1892 model Waltham pocket watch by the way...

The second balance staff went well,except I kept dropping it on the floor and bent the pivot. My attempts to straighten were to no avail. So I have sourced another staff. The problem with this staff is the pivots are 13 size instead of the 11 they should be. I have a Seitz jeweling tool as well as a nice Jacot tool. So my question is, leave the pivots alone and put in new balance jewels or turn down the pivots with the Jacot tool. What is the accepted practice? My first attempts with the Jacot tool brought mixed results. I found my new pivot file/burnisher very quickly took the bent pivot from 11 size to a 9 very quickly. 

Waiting for my bench practices book to arrive...

Ron it is what you are are confident with.Changing the jewels is relatively easy and reversible if it does not work. However if it was me I would adjust the staff using a jacot tool or the easiest option is to purchase then correct staff and keep or sell on the wrong staff. 
What fun.:)

I guess if you put these in order of risk from least to most then it's

1 - Find the correct staff.

2 - Replace the jewels.

3 - Modify the staff

But then again, as a learner, I like to challenge myself to take the more risky option in order to gain experience. But of course that can be an expensive choice.

    • 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
