Hi

The ratchet wheel screw on this watch was very tight and it will not come out all the way. I'm wondering if the screw is stripped or someone actually glued it in place.

It turns now but it won't come out. 

Any ideas?

I'm just trying to clean it; it's very dirty and needs a new setting spring but it still works.

it might be a left-hand screw, and trying to unscrew it to the left would break the thread in the barrel arbor...

it happened to me...

Sounds like it's stripped the threads? Was that with you there? is it the barrel arbor screw that is stripped: That is probably left hand? Not the most common movement either?

Hi Guys

The crown screw was definitely a LH - to tighten - screw but the ratchet wheel seemed to be a RH screw. I've been wrong before...

But, if it's broken, you'd think it would separate from the barrel arbour easily. 

And, yes, it isn't a common movement.

The Citizen 200 movement has a LH thread on the crown wheel AND ratchet wheel! Some of them are not marked either!

Try both ways... hope it works out!

I think the screw may have been broken off at some point because it looks a bit ragged on the end.

Plus the barrel arbour may have bad threads. 

Not sure. I need another setting spring but it's hard to find parts for an AS589; as you say, it's not a common movement.

I am not sure but could it be that the the thread is lefthanded because the barrel sits on the left side? Look at other movements it's usually to the right? 

If i think right the barrel should turn in the opposite direction to the other one? And need a left hand screw? 

Found this on ebay. http://www.ebay.com/itm/1930s-AS-589-7J-running-National-Solar-Watch-Co-Cal-1100-watch-head-for-parts-/142310626231?hash=item21225fd3b7:g:14EAAOSwf-VWW6pd

      What's your thoughts on this Rolex Sea-Dweller, ref. 16600, calibre 3135 project?

      By VWatchie · Posted

      Well, my fundamental stance is that I want to go in and out without leaving any trace other than a shining, perfectly running movement. So, no scratchings on the inside of the case back lid, no marred screws, no debris, no fingerprints, and so on. That is, my goal is to make it impossible for the FBI to track me down. As a professional, I suppose you might want to keep track of returning watches, but as @JohnR725 mentioned, we can keep detailed computer records without marking the watch at all. That may not be true for every watch, but luxury and COSC-certified movements do have unique numbers. John also says it’s best to leave no sign you were ever there, and I couldn't agree more. Now, suppose the Sea-Dweller I'm working on is one day scrapped, and you want to sell the case-back separately (perhaps the case was destroyed in a plane crash). Then the scribbles on the inside no longer reflect the current movement inside the case. Also, the engraving will likely halve the market value of the case back. It had been "sleeping" for about a week and a half. Yes, the "debris/old lubricant" theory is my hypothesis as well! It will be interesting to see what I find once I have time to start disassembling the movement.

      I've repaired a few of these, having some success with stripping and cleaning the mechanism.  They are so cheap though, its hardly worth the effort in many cases.

      Id love to see how he has the output shaft mounted to this setup, as I have the same rotary stage and stepper in my build.

      Broken watch stem in watch crown

      By Poljot · Posted

      If you see at least one thread protruding, or even a half, then you may have a chance using this "tool", but don't squeeze hard. Lot's of patience, and if you notice any signs of loctite or other adhesives, then apply several drops of acetone on top of broken stem. Use heat (hair dryer) also. You should be able gradually turn it counterclockwise, just like i did on this broken Timex stem, which was glued with something like nail hardener. Then you can use an extender to save your broken stem. https://m.media-amazon.com/images/I/513DVvkfW5L.__AC_SX300_SY300_QL70_ML2_.jpg   You can also try cutting a small grove / slot on top of the broken stem to use 0.7mm flat screwdriver.   Depending on the Crown material and Stem material, you can try dissolving the stem.
