Elgin Pocket Watch Mystery Screw.

I am new to watch repair, but have successfully repaired, cleaned and oiled several pocket watches.  This picture is from an Elgin pocket watch that I am currently working on.  The piece indicated by the arrow, obviously assists in toggling between winding and setting via the clutch pinion but, as you can see, there is no screw in the hub to hold it in place.  However, in the bridge, above the piece indicated, is a small screw in a threaded through-hole that is not retaining any other pieces and, at first glance, appeared to be doing nothing.  I assume it is there to somehow retain the piece shown, and possibly adjust the resistance/tension of that piece.  I've haven't seen one like this yet.  What exactly is the mystery screw supposed to be doing, and how do I adjust it to do so?     post-1801-0-20526400-1457103006_thumb.jp

Using a little tiny bit of oil to hold the piece in place worked great!  Thanks for the wonderful advice.  Also, I think I solved the mystery of the real purpose of that screw that appears to be doing nothing.  It seems to be there to hold that piece locked so that there is no tension on the tail piece in order to allow the stem to be inserted without spring pressure on it.  After I screwed the bridge into place, I rotated the wind/set mechanism to take tension off the stem, then snugged the mystery screw down just enough so that nothing moved.  After the stem was in, I backed the mystery screw off, the tail piece engaged, and the wind/set mechanism snapped itself into place.  Wow, a screw that seems to be doing nothing sure was confusing for a beginner.

      Oh nice. I have a similar wedge style stump for my staking tool, so I'll give that a shot. Thanks!

      Gamblin Gamsol for cleaning?

      By joelcarvajal · Posted

      Thank you all for the replies!  Very informative! True enough, the Gamsol took some time to evaporate and does leave a residue. So not all naphtha are created equal!  Need to find alternatives then. i was able to try Hexane recommended by Alex and it seems great.  I wonder what the cons are?

      Yeah, I saw that in the tech sheet but I don't see how it can be adequately cleaned with the friction pinion still in place. I've accidentally pulled the arbor right out of the wheel once when I used a presto tool to try and remove it. Mark shows how he does it with the Platax tool. Those are a little too pricey for me so I got one of these from Aliexpress and I just push down on the arbor with the end of my brass tweezers. That usually gets it most of the way out and then I just grab the wheel with one hand the and the friction pinion with the other and gently rotate them until it pops off. Probably not the best way but it's seemed to work for me so far.

      Movement inserted from crytal side

      Thanks, Jon Sounds like a plan. Obviously I'll have the face on so do you think gripping with the holder will create any problems, but I will check in the morning to see how feasible it is but I assume it only needs to be lightly held. As for holding the movement instead of the holder won't be possible in this scenario as one hand will be puling on the stem while the other pushes the spring down. That was my initial concern is how the hell can I do this with only one pair of hands. All the other times I've had to remove the stem hasn't been a problem, apart from the force required to release the stem from the setting lever, but now I need to fit the face and hands its sent me into panic mode. If it had the screw type release things would be a lot simpler but that's life 😀   Another thing I will need to consider is once the dial and hands are fitted and the movement is sitting in the case I will need to turn it over to put the case screws in. I saw a vid on Wristwatch revival where he lightly fitted the crystal and bezel so he could turn it over, is this the only option or is there another method?

      Main spring

      Hi Jon, do You think that relation spring torque - amplitude is linear? I would rather guess that the amplitude should be proportional to the square of the torque. I had once idea to check it, but still haven't.
