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.
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?
Zero to do with watches, but the place has been a bit quiet and if all we talk about is watches, well, no one gets to know anyone.
Five years ago after 25 years of professional services, I completely lost my mind and bought a defunct manufacturing business and have slowly been building it up. Here's some shots I took yesterday of a couple of current projects we're just finishing up; a medium size box girder overhead crane and a lugger truck body. Apparently we've got an 80ton crane coming in; 110' long, 5' box girder - that's a large crane! I mess about with machining, welding, electronics and bit of clocks and watches for kicks in my home shop, but I've a lot pride in the team here, these are the people who really know what they are doing.
Hopefully we get some more day job "show and tell"s....
