Hi All

I'm a beginner having "serviced" or restored about a dozen movements without killing them.  I dropped a newly acquired watch containing an ETA 2472 and it stopped.  Before I send it off to a real watchmaker, is there any checks I can do to determine what broke?  There's nothing obvious with the top incabloc.  The hands set.

Thank you

Charlie

If you give the balance a gentle nudge or a puff of air, does it oscillate normally, or jam up on something? Is the hairspring tangled?

The hairspring is partially blocked from view by the autowinder but looks to be ok.  The balance swings with a puff in one direction but not the other.  Could it be the position for the impulse jewel and fork?

Yes it can;  perhaps impulse jewel can't enter the fork horn, if the shock has  knocked a pallet jewel out of alighnment or bent a pivot.

Remove the two black screws then the automatic device, loosen the cock screw by couple turns, raise the bridge just enough to pass the impulse jewel over the fork so to get impulse jewel inside the horn, tighten cock screw.

It will run, however , might get stuck again if pallet jewels have got misaligned or a pivot has got bent.

Hi Charlie, you underestimate yourself. You are not really a beginner any more. You have identified where the problem is. Without removing the balance assembly and inspecting the pallet fork and the escape wheel, you can't diagnose the exact fault. Your watchmaker will be able to do the rest. You can try what Joe suggests, and it might run well after, If you are very lucky. After that, you need to decide between a DIY disassembly and parts inspection, or an immediate trip to a professional.

Nucejoe was correct.  It appears that the fork got displaced on the other side of the impulse jewel.  Amazingly nothing broke and it's now working.  Thanks to everyone for the help!

Hi Charlie,   

  You did fix it yourself, didn't you?     Klassiker is right.

I think you decided to start all your posts this way, to spare us all reading comments that may sound discouraging.

Good luck pal.

      Vintage pocket watches from e-bay (winding stems needed)

      By nickelsilver · Posted

      These are all American movements (with the exception of the "Rubis"), and are all almost certainly "negative set" which means the stem is part of the case. So it's normal that they are all missing- they are with their cases. You will need male square bench keys to wind/disarm them. Vintagewatchstraps has a great writeup on the different systems. But basically, any American "x" size movement will fit any case for that size, possibly with some adjusting of the stem position. With Swiss movements, there is some interchangeability between calibers, usually within the same maker's range, but not really overall- there are thousands of different stems out there.

      Vintage pocket watches from e-bay (winding stems needed)

      By Mallard · Posted

      Hi, I'm very new to watchmaking and this is my first time posting here.  I've bought a lot of 10 vintage pocket watches size 0s from e-bay and just got them today.  Most of the balance wheels sprung quite freely and thus seemed like a worthy endeavor as a first batch for exploration.  I've just realized that none of them have any winding stems. Is there any way I could source appropriate winding stems for the movements? There seems to be assortments of various stems selling in bulk on aliexpress, but would any of them fit?  I've read on other threads that some people lathe their own stems (which is waaaay out of my current skill set, which is pretty much nil). Others say that you 'just have to try a few and see if they fit'. I would much appreciate any advice for this matter. Thanks!

      Movement holder made with 3D printer

      By LittleWatchShop · Posted

      Nice work.  In the last year, I have been servicing Accutron 218s.  I have the official Accutron hoder that provides electrical contact to the movement.  It is a pretty clever design.  There is a cut in the ring of the holder (shaped like a "C").  When in relaxed state, the holder is slightly smaller than the watch movement.  You spread the cut slightly and drop the movement in and release.  Very clean.  I have made 3D versions of this setup.  Have not explored using it generally for other movements.

      Tool of the day.

      Double Oooooo   Removal tool? Dreamed of one of these. However, Kalle on Chronoglide showed everyone my system with the pegwood. Worked a treat. Felt so chuffed to be mentioned. https://www.youtube.com/watch?v=tTFrXjiyGKc 46:40 for the wheel removal. Mentions me at 50:00 and does the removal with the pegwood. Felt like my 15 minutes of fame.
