Hello, I've been struggling for two evenings now to fit the train bridge on this ETA 2832. Every time it looks like all pivots are aligned through the jewel holes and I begin tightening the bridge, the wheels begin locking up. On closer examination, it looks to me like the 4th wheel is not seating flush against the centre tube as shown in one of my photos. I believe this because the pinion on the 4th wheel is higher than that of the escape wheel, and equally about the same measurement out between the 4th wheel and the 3rd wheel pinion, which is lower. It also looks like the 4th wheel is fouling under the train bridge.
In your opinion, would my suspicion be correct or should the 4th wheel's pinion rest approx. 1 to 1.5mm above the flange of the centre tube. If it should be flush, do you have any tips to seating it as such? I have obviously tried carefully wriggling it under light pressure without luck. I've added an extra photo showing the placed wheels during disassembly to give some context.
Thanks in advance
Join me as I strip down, service and review this Chinese ETA 2892-A2 clone. Seagull ST1812 watch movement. There was a couple of issues to deal with but altogether a fairly impressive movement for the price.
Im working on an ETA 2783, and suspect that the canon pinion is to tight against the lower wheel.
So I have to make it a little bit more loose...
Has anybody done this befor?
And how it the best way to do this?
Working on a Tudor Oyster Prince with ref no: 2081/4 with a ETA 2784 movment.
Cleaned and inspected, all looks good, no sign of wear and tear on the main spring, no sharps bend, looks overall good. Noticed that there where some marks on the barrel wall. But that I have seen before witout any drama....
Oiled it , put togeher , goes like a dream..... but the the spring does not stick, it snaps over after 6,5 turns by crown.
So the question is:
Can I just replace the main spring?
Can I just replace the main spring and do something with the barrel walls ?
Buy a new barrel with spring? Is it to be sourced?
Hello i am trying for the love of God to repair a 6119c, I bought another movement for spares, I have watched a number of videos on some one else dismantling and reassembling the same movements. I used an ultrasonic like i do with any other movement and cleaned them both up, I put it back together and then the day wheel disc and the date dial, once i put the dial on, they seem to sit 1/2 off each other. any ideas or feed back would be good.
Balance wobble thoughts:
1. Balance staff pivot may be broken.
2. Jewels are reamed out.
3. Balance pivot jewels not seated properly.
4. Balance pivot jewels cap springs could be upside own or bent.
5. Balance cock not seated properly.
thats all I can think of.
Reading through a service sheet for the Rolex Daytona and the movement has a 'regulation nut' under the balance bridge. You can adjust this to get the correct endshake. How is this measured? Is a special tool used?
