Success! Removing rusted dial screw

Recommended Posts

I recently acquired a Waltham 0/size 1907 grade 165 pocket watch. When attempting to remove the dial, one of the 3 dial screws was rusted firm in place. In order to get this stubborn screw out I purchased some Hoppes #9 Gun Bore Cleaner from amazon. I used a small glass dropper to carefully apply some solution to the screw from 2 directions. I placed some directly into the screw hole on the side of the plate, and I also applied some directly to the dial foot visible from the plate. I was a bit concerned about potential damage to the keyless and motion work since they were both still in place beneath the dial.

I needed to reapply the solution for each of 2 days. So after a full 48 hour soak, I was able to very easily remove the screw with a normal screwdriver.

Thankfully there was no damage to the other components of the watch. I immediately disassembled the remaining components and ran them through the ultrasonic to remove the solution. I still recommend caution using this solution with other types of metals....

Hope this helps someone else!

Interesting - it has a pretty distinctive odor - and now that you point it out I do believe there's quite a distinct "nose" of kerosene  :)

Any thoughts on potential watch damage based on this list???

good show,  i have had the same dial screw problem.  next time try KROIL,  it is slightly better than hopies.  heat and time also helps get those buggers out.  vinn

      I've got an old Nvidia Ladies Watch with an ETA 2360 movement that I'm trying to get up and running. The movement looks nice and in good shape and luckily I also have som spare parts lying around. The dial is mounted with tiny screws on the sude of the movement. There seems to have been som moisture ingress into the movement since I can see traces of rust and, of course, one if the dial screws has rusted pretty bad so I'm unable too remove the dial. I can see the groove in the screw and I can fit a screwdiver there but the screw is really stuck. I've tried putting some WD40 on it and letting it soak for a day but to no avail. 
      How can I remove the screw ? I have extra screws if needed so I don't need the stuck screw.

      Most of my learning efforts are on old, vintage movements; some in great shape, some not so much.  I often find a screw or two that are stuck tight.  Not rusted, just "aged-in-place"  I try typically to put a drop of 9010 on the back side of the screw hole and let them sit and soak.  Sometimes this works well.  I gently heat them by moving my work light close to the movement and allow them to cool which may help move lubricant into the threads.
      When this doesn't work, I'm stuck (no pun intended).  Have you a method that also help loosen these old screws up?  If so, please share it.

      So, while waiting to fix the Seiko misadventures of my youth, I went looking for broken pocket watch movements on ebay. (I had read somewhere that a good way to start is clocks for their larger parts, then pocket watches as an intermediate stage and then wristwatches for the smallest movements and parts.) After losing several auctions for promising non-working pocket watches I found a New York Standard possibly "Model 11". It was mostly disassembled and there is much rust/corrosion. I think it's missing at least the clutch, for example. It needs new hands, but this isn't impossible. The main problem here is the rust. It looks like someone disassembled this watch on purpose but I don't know how it came to be so rusted. (Maybe it was parted out? It would be nice to have a tech book on this watch.) 
      So I've been looking over rust removal methods. One video says to use water and baking soda with a brush. Many advocate the use of a "solvent" without being very specific. I have a .pdf of a 1940's War Dept. Technical Manual for watch repair. (you know, for when you're in a trench and taking fire and need to know what time it is but your watch is broken) Among other things this book recommends using pith and I think maybe pegwood as well as solvents or the like that are only referred to by what I think are military requisition numbers.
       My circumstances are such that I can't afford a sonic jewelry cleaner, and I don't have a dedicated work area and limited storage for tools. The baking soda method appeals to me but I think this works mostly by abrasion, the baking soda being gritty. I'm afraid this could damage smaller parts. I could upload pictures if anyone's interested.

      I have recently gotten interested to learn and acquire knowledge about watches and there movements.
      I have a question for the initiated,if there is rust in the parts of the watch must the patts be replaced or can they be cleaned with a rust removal process or is that not advisable due to the parts being very fragile in nature.
      Thanks again for youre time.

      Can anyone help me with this problem? I have a size 12 american pocket watch that has what appears to be the wrong screw in the nickle  barrel plate. I need to remove it. It won't turn left or right, the head doesn't protrude far enough to grab it with a pin vice.
