I'm currently building a custom watch with an ETA 2892-2 movement. The movement is from an old Brietling. I managed to fix it and was working perfectly. I was in the process of putting it all together, was attaching the second hand and it suddenly stopped. I believe I may have used too much force. However, I have taken the watch apart again (about the 12th time!). I notice that when I move the hacking spring it stops as it should, but when I return it to the position that would usually allow the movement to move again it doesn't. I assumed I'd knocked something out of alignment, but to add to the confusion if I give the escape wheel the slightest nudge it continues ticking. It's baffling me.
Anyone have any ideas?
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?
ETA type of Center Wheel/Cannon Pinion
